On my i7 6700K build, to save money was trying to utilise an old case, but as learnt about various components and matching and maximising performance of them all realised this was a false economy, that would have meant none of the maximum performances would've be available due to limited cooling and was wanting a quiet pc, but the older case had no sound damping aspects. I have posted to the thread on case choices, as came a cross another poster with a similar choice.
http://www.tomshardware.co.uk/answers/id-2858298/fractal-design-quiet-base-600.html

I had originally ordered a BeQuiet Shadow Rock slim air cooler, thinking it was lot better than the stock fans and many of the most popular entry level air coolers, but on checking out performance with overclocking discovered that the slim model was designed for base usage without any overclocking. Managed to get a return accepted, along with 2 smaller fans that at 80mm wouldn't fit modern cases. I decided using one of the latest cases, a Fractal Design R5.

Next is to get an optimum cooler, air or water. I like the ultimate quietness of air cooling without any water pump noises along with louder fans on some models. Aldo have read about leaks and a leak on expensive components could be s disaster and cant afford to replace pc. The disadvantage of big air coolers are the weight and size, although with a decent fitting bracket should be ok.

After checking performance levels of all the models, have moved away from what I was going to go for. Instead of the Shadow rock slim, that is good for general computing, but totally failed when overclocking and struggled to meet stock settings on 6700K, according to several reports, I was going to go for the higher performance BeQuiet Dark Rock Pro3, that did meet stock settings, but on test bench results on full overclocking, this failed as temperatures went too high, although in normal usage it probably is fine. But one model that’s outstanding is Noctua NH-D15 which performed well under the toughest of tests. In fact the performance is so good it exceeds all the entry level and matches or slightly exceeds even most of the popular mid-range water coolers. The only cooling that beats it is the most extreme top range super overclocking water cooling options. I am going to overclock but not to the extra range, a comfortable regular working range.

Noctua NH-D15 http://noctua.at/en/products/cpu-cooler-retail/nh-d15.html#.Vk3FceKYAvk There is also a new single fan version NH-D15S This new version using one fan, has performance when overclocked showing only 0.94 degC higher than the dual fan setup on NH-D15
http://noctua.at/en/nh-d15s.html#.Vk3JhuKYAvk only this does not seem too widely available, also if get the double fan version, can install it with just one fan and use the second fan for an extra high performance low noise case cooling fan.


I have decided to go for G Skill Triendt Z high performance fast Ram either in 2 or 4 slots depending on if I go for 16Gb or 32GB, so shall use either 2 or 4 DIMM slots on the mainboard, an Asus Z170A as this board has all the specs I wanted and the extra cost of the Deluxe didn’t add features required and didn’t need a gaming prioritised board and in nay case it has plenty of gaming options too, seems a good mid range board an d fully Skylake compatible.

My concerns were if the board can accommodate the weight of the Noctua NH-D15, but with careful and secure fitting into the Fractal Design case, I think it should be fine. The consequences of a damaged board due to weight would be a new board, although if handled carefully weight distribution and fitting should be fine, but a water cooling leak could ruin all components. And many tests show this air cooler equals many mid range water coolers, but is also quieter well as no water leakage risks.

Because of fusing the TridentZ, which I am well pleased with the choice, am awaiting delivery, and the same would apply for Ripjaw IV or Vs, or Dominator Platinum, the clearance for the side fan of the air cooler over the ram is well known to be an issue. Options include raising height of fan from mainboard. The following video at around 6:15 shows adapted with outer fan raised for higher profile ram https://www.youtube.com/watch?v=QtYMX73XsDw it also mentions weight, but appears to be well secured to the board. Raising the outer fan is facilitated by utilising the clip fan fitting. The height of cooling unit with fan 165mm http://noctua.at/en/products/cpu-cooler-retail/nh-d15.html#.Vk3FceKYAvk so if a wide computer case is used, could accommodate the extra height. For Fractal Design R5 case maximum height from mainboard that can be accommodated is 180mm http://www.fractal-design.com/media/f17f104d-ad97-437b-b8a0-f48dd425d988 , so room to add up to an extra 15mm over ram DIMMs.

Other alternatives include only installing the middle fan, but that has a performance reduction from using one instead of two fans, however it appears to be not a very large reduction, following test indicates 2 degC with i5 running at near 4.5GHz http://en.watercooled.ch/noctua-nh-d15-review/ although when overclocking it is preferable to get maximum cooling, so use two fans if possible, although it still appears to meet according to that benchmark test, heat reduction on one fan even. Also the case I'm using comes with 2 pre-installed fans, but I'm considering getting an extra front fan and possibly install 1 roof fan to add to the 1xfront and 1xrear included fans. This would increase input airflow but also output near to the CPU mainboard, so may more than make up for only installing one fan attached to the cooler, the most important central one. Also using the Fractal Design case, installing a second front fan and removing the middle drive bay unit could allow a direct airflow from the front intake fan in line with the cooler anyway, as well as the standard outlet fan behind the mainboard and cooler. This airflow setup could probably be done on many cases by removing the central drive cage and installing a second input fan in that location.

I was wondering whether it's possible to of course install the provided 140mm fan, but instead of using the included second 140mm fan above the Ram DIMMs, to utilise that fan by installing it as a quality fan as intake or output depending on orientation in as extra cooling in the case, then instead getting a smaller fan, say 120mm, if would fit or less if necessary, that is small enough to give clearance to high profile ram. Another high quality quiet fan could be used or an LED one that is as good as possible in low noise to keep the build a slow noise, could add colour if using a window side panel. That way the high quality Noctua fan would still be utilised, but meaning a second cooling fan to the profile would still be set up for airflow across the cooler.

There is a 12mm height difference between the top of Trident Z Ram and the front fan edge. If raise fans, using clip on cooler by 14mm this allows 2mm clearance above the ram fins and takes the height of the top edge of attached fan to the cooler from 165mm to 179mm, so 1mm within panel specifications for Fractal Design R5 case. If combine changing the outer fan to a smaller front fan with raising the height using the clip fitting, this means get larger clearances above ram and from case. The smaller fan could be ordered from Noctua to match design and colour, and maintain same low noise high performance, possibly with a slightly lower bench mark although it may be very close as the only difference would be being 120mm fan at front instead of 140mm and of course keeping the central 140mm fan. Noctua additional fans, if could be fitted include 92mm at 2000rpm http://noctua.at/en/products/fan/nf-a9-pwm.html#.Vk3ygOKYAvk or 2200rpm http://noctua.at/en/products/fan/nf-a9x14-pwm.html#.Vk3z7uKYAvk
Although these are much faster may need to consider balance with 1500rpm central fan, then again as the central fan is bigger volume of air may be similar. If want to go for identical airflow could use 120mm fans for middle and outer such as Noctua http://www.dvtests.com/noctua-nh-d15-test-and-review/ and http://hexus.net/tech/reviews/cooling/69073-noctua-nh-d15/?page=3
In terms of using 2 different size sof fans it appears that BeQuiet Dark Rock Pro 3 does just that with a 1x120mm and a 1x135mm fan an dboth running at up to 1700rpm http://hexus.net/tech/reviews/cooling/69073-noctua-nh-d15/?page=2 but bench test reviews show a significantly higher performance of the NH-D15, although the dark Rock pro 3 is actually also very good, but the advantage of the Noctua comes to the fore when tested on mid to higher overclocking where this difference can make all the difference.

There may be the option to add a third fan of 120mm or 140mm, which from searching appears to indicate only a very small improvement, normally not making it worth it, however that small improvement may compensate for using the 120 instead of 140mm at the front. And the spare front fan could then instead be fitted on the back with extra fan ordered for the front, or if not used in a three fan configuration could be used as an extra fan anywhere else on the case for extra cooling and airflow.

Other alternatives could be replacing one or both of the high quality low noise 1500rpm max fans included with the air cooler, whilst re-using them in another part of the case, with alternative low noise ones such as BeQuiet Shadow or Silent wings 2, or some may like adding colour with Led fans, although these may not be a slow noise could fit a colour theme. Also wondering if cooling properties could be boosted further by adding fans that had faster fan speeds, for example the BeQuiet 92mm fans are at 1800rpm http://www.bequiet.com/en/casefans/323
, with 120mm fans at 1500rpm http://www.bequiet.com/en/casefans/322
Also the faster speed may be compensating for being smaller, but 92mm could be ideal to give plenty of clearance over the ram. So on the outer fan, instead of using the 140mm fan could use 120mm or 92mm over the Ram DIMMS or just use a faster 140mm centre fan, that is in addition to having several case fans.

From looking at this cooler differences between air and liquid cooling seem diminished. Advantages of a top quality air cooler like this include very low noise and also having a cooling effect on nearby components, including the Ram, as well as the CPU, plus no risk of water leaks. This air cooler seems to provide all the necessary properties combined with correctly installed other components and good case airflow, to be able to use the latest Intel i5s and i7s processors up to mid to high overclocking, with only extreme overclocking setups requiring specialised high end water cooling.

Started out asking the question what to go for high performance air cooler or mid range water cooler, after going into these details am about to go ahead and order the Noctua and modify the outer fan to fit with the G.Skill Tridents, in a Fractal Design window case.
 
Instead of shuffling the fans all over, or moving them higher on the cooler, why don't you shop for DIMMs that do not have such tall heat spreaders?

HERE (LINK) is a RAM compatibility table for the Noctua NH D14. I have this cooler in my rig and the Crucial Ballistix Tactical fits without any problems. Of course, mine is DDR 3, but the table does list several Crucial DDR 4 DIMMS that also fit the NH D14.

I can highly recommend the NH D14! Great cooling and very quiet.

Yes , thanks and Toms reports are always good and useful, such as this one on this item http://www.tomshardware.co.uk/noctua-nh-d15-cpu-cooler,news-47639.html and many more articles and questions too, seems very popular, with people comparing and realising unless they are going for a high end water cooling solution it actually is better for many reasons, or simply for a low profile aesthetic, but for me quietness and no risk of leaks are more important and performance that also exceeds lower end water coolers and sits in the middle of mid range ones too.

The more i read about CPU cooling, including trying to select and chose a water cooler, the more I realised the top performance and security of the Noctua, a really solid piece of kit. Performance it blows cheaper water coolers out of the water along with all the cheaper air coolers. In all the tests I've read it goes beyond the level of clocking required, as probably will go for not far above the 6700K stock settings, probably to about 4.2 to 4.4GHz max. For a water cooler to beat it, seems it has to be higher end, also big radiators and even custom builds and all have risk of leaks. Also as I like a quiet build many people report problems with water coolers having pump noises as well as still requiring fans.

I'm wanting to add an extra front fan, only choosing from quiet fans to keep it a quiet build
may add BeQuiet, Noctua or Fractal Design. But am wondering if it will be best to add an extra fan attach top to even out the air pressure and increase air flow further in the case. Also with a fan at the back and at the top will a lot a lot of hot air to be expelled from the mainboard, above the CPU cooler and Ram areas. Also noticed many tests to keep comparisons standardised often did not include extra fans, so with extra fans in quality cases, its possible that benchmarks may exceed what are already excellent ones.

In the Fractal Design case and maybe attaching some kind of plate with large space to keep dust out when not in use, although a fan would be located there that would also help keep dust from falling down as a filter would restrict it as an output, but when on, the air being expelled will keep dust out. Together shoudl make a good cooling set-up with good airflow whilst also being a quiet PC.

NH D14 is also excellent of course, as is the latest NH D15s and that doesn't have the Ram clearance to accommodate, but on reading various reports its not quite as good as the 14 and 15 when overclocking, which to me the extra performance there is good to minimise CPU temperature, but it still is good. And low profile ram is another alternative of course, only I spent ages deciding and eventually went for Tridents. Also many people, for good reasons, like Ripjaws, Dominator Platinum and other good higher profile rams, but there are also plenty of low profile ones too. Just in this case don't mind adapting it so means can still use the Tridents.

I have included some performance results on testing my desktop rig set-up using the Noctua NH D15 on another thread on this site http://. All the components are working well together. and the results for the air cooling with 6700K processor, over-clocked at 1.264v to 4.5 GHz, Asus Z170-A mainboard and G.Skill Trident Z 32 GB ram at 3333 MHz (OC) with the Noctua are impressive. Mostly in a room at 17 to 20 degrees it is typically idling at 19 degrees and under normal load 20 to 26 degrees. Most of Prime 95 was at 62 to 69 degrees with spikes up to max of 81 degrees and cpu up to 1.39 v during the toughest stress tests at 100 % on all 4 cores and with 32GB in 4 sticks of overclocked ram at 3333 MHz and running Office, using a web browser and watching YouTube 1080p video, using several monitoring programs and integrated graphics without a graphics card and using 2 monitors at 1080p.

I may have to check how I set the fans speeds though as was expecting them to run near to max, but they were mostly running at between 340 and even under maximum stress in Prime 95 the 2 fans didn't get above 745 and 748 rpm, yet the rated max is 1200 rpm and I didn't fit the low noise adapter. When the most extreme stress tests were completed at highest cycles temps quickly fell back to 60s and when stopped Prime 95 it immediately fell back to 26 degrees and even down to 18 degrees. I checked the fan profiles, seemed when tweaking with various settings had set for ultra quiet fan profile and 100% only started at 80 degrees, have set new profile, shall have to have another go at tests with the new profile.
 
I started my first ever overclock yesterday. I currently have a thread in the CPU forum, where I put my overclocking question in error. I'm using a Fractal R5 case, an Asus Maximus VIII Hero MB, a Noctua NH-D15 heatsink, an Intel i5 6600K, and G. Skill 8 GB x 4 Ripjaws V RAM. I'm only using the middle fan on the D15. I moved both Fractal fans to the front, took out the 5 bay drive cage, and made the extra Noctua A15 fan a rear case fan (plugged into the CPU_OPT header). Since I am trying to keep my voltages below 1.4 (max measured 1.44), the temps have been great with the highest about 73 degrees (it's cool here, that's ~55 degrees over ambient). I think the i7 does get a bit hotter than the i5, I hear, due to the hyperthreading. It's also hotter if you use the onboard video instead of a separate video card. None of the fans ever exceeded about 1000 RPM in Realbench stress testing. The Noctua SecuMount is the best in the business and I have no concerns about the chip or MB being damaged (though I am not shipping it). The Hero MB may be a bit more robust than the A170 however. Any questions about my set-up, ask away. (and read my post in the CPU forum)

I also have a Fractal Design R5 case, its a really good case with so many options. After getting the Asus Z170-A board, i did wonder if should have gone for Hero, but on reading specs the one I went for does do all I wanted and it appears to be as good a quality with extra cost for additional features. It is really very good value and some good reviews remarking on it not skimping on features, its just extras and there isn't that big a difference between the A and De-luxe or Hero and cost is important overall, so as long as quality isn't compromised and I must say the A series board is good and does seem well-built. I didn't need wi-fi and am not likely to need more than one m.2 slot and it does have PCI express for further high speed cards.

I ordered the board first and by the time the i7 chip and ram became available i had the board over a month, but saying that it is a good board and seem sot be well made, possibly as good as the Hero but without the extra features. Regarding ram speed 3400 an din my case 3333 MHz is probably fast enough for most people on Skylake platform, any faster and like hifi is following diminishing returns. It is certainly a point in using a graphics card,I am aware with using the on-board graphics it will place more load on the chip, but it seems designed to cope, just as long as its not for gaming that is. In fact performance up to 2-d is quite amazing, its 3-d when the graphics cards really take off, but saying that using graphics card will let processor and as graphics are constantly used should help keep temps a bit lower. I do want a grpahics card, but from what ive read the Pascal series are such an improvement and match a lot of the features of Skylake, its worth waiting and in the meantime use integrated graphics. I'm also using 32GB ram with all 4 dimms which will add a bit more heat possibly, although from my first test it doest seem to make that big a difference, more benchmark difference, but higher capacity fast ram does seem to help performance.

I also read about the issues some are having on attaching heat-sinks to Skylake processors, but Noctua do seem to be extremely well built with a very good solid mainboard adapter plate. I also would consider detaching for transportation, but I think that may be a good idea for most heat-sinks, certainly air cooled ones. As regards pressure, water cooler heat plates also if fit too tight or from a lower quality may have the potential to be just as damaging so the answer in attaching any cooler whether air or water, is to do it carefully. The Noctua fitting seems ot be one of the best available and seems to enable attachment with a good balanced contact and easy to fit without over tightening. I also found the cross method of thermal paste effective.

Regrading fans I have set manual profiles that both allow quiet running, but move into turbo from 60 degrees,I've made a new profile since the test I did the other day, that follows quiet pc mode up to 50 degrees then has a steep curve to high at 60 degrees and full at 70 degrees. In addition to the 2 fractal fans that are very good and quiet, I'm using both, I've added a Be Quiet silent wings 2 as a second front fan. I'm also going to get an M.2 to be my main SSD supposed to arrive this week and have another Be Quiet fan I'm going to put in the base in front of the power supply, and this is well placed to blow cooler air across the m.2 and towards the processor and ram, so will have 3 input fans, 2 in the front, one underneath and 2 fans on the cooler, one output fan. I am considering with having 3 input fans, may add another output fan at the top, but think I'd need some kind of cover above the fan to stop dust dropping down into pc when not switched on, or use an air filter and a high static pressure output fan.
Update on using the Noctua NH D15 in normal PC usage, temperatures have been low and run very quiet. I have changed the fan profiles through UEFI that were set at quiet and normal to turbo settings, that stay as quiet at low to mid temperatures then instead of not going to full speed until over 70 degrees C going up to full speed at 60 degrees C so cooling is increased earlier and maintained until temperature fall to lower levels, which is also more rapid. I have also added another fan at the base when I installed a Samsung 950 Pro M.2 SSD to use for Windows 10 operating system and gives very positive air pressure, but ensuring a powerful fan at rear the Fractal Design one is connected to main-board enabling full power. I've got the processor over-clocked to 4.5 GHz at 1.3v offset and mostly it runs at much less and ram at 3333MHz with 16 18 18 38 and it is performing fantastically. CPU temperatures in normal usage at 16 to 24 degrees C. and along with a Corsair RM750i power supply is very quiet whilst high performance.

Update: I have overclocked the Intel i7 6700K processor at 4.4GHz with 100 BCLK, adaptive mode. I found setting it at 1.30v works but 1.32v allowed stable operating for more demanding tasks and mostly at very low voltages such as 0.795v. I had a close call using offset, as there was an error when using Asus software tweak, immediately corrected and was not my fault, as I had only set it to 0.01 and ensured I had, but has put me off using offset. The 2 Noctua CPU fans kicked in instantly going to full and gave enough time to take voltage down to 1.2v manual, allowing to cool and later setting up a decent adaptive setting. I also found offset tended to use higher than required voltages, as did the Asus software set-up. Manual allows full control but meant to ensure stable , always running more than required. Adaptive is proving very good, mostly running very low voltages and very low temperatures, with Noctua NH D15 air cooler maximum temperate 63 degrees C. with Ram set at 3466MHz (Intel XTU Benchmark on Asus Dual Intelligent Processors 5 software).

As I am using my desktop pc just with integrated graphics until Pascal graphics cards are released, didn’t want to overstretch the processor as all graphics are currently being run from the CPU only, I have therefore changed the overclock to 4.4 GHz and when add a graphics card may up it to 4.5Ghz. I have also added Intel Tuning Replacement Plan https://click.intel.com/tuningplan/ via Intel website as discovered overclocking Is not included in standard 3-year warranty terms, but that allows for any major error that may occur including not user error, so no matter how careful one is, software, hardware UEFI bios etc, that may damage the processor. Of course when one gets it running well don’t want to change processors, just as well to be covered, so can just enjoy the performance of the processor with ram.

The Noctua NH D15 performs superbly and in regular use am finding temperatures between 17 and 23 degrees C and ultra quiet in Fractal design R5 case, as in would require am amplified microphone to detect, so ideal for quiet and cool pc.
:wahoo:

Yes, exactly, the R5 case is superb, I've gone for a white one with window, looks good as well as functional, its also a quiet case, ideal for ultra quiet computing, for production work, also lots of bays that are removable for airflow or if have a mammoth hard drive raid system as well as SSDs and will so many options for air or water cooling, including custom loop, and of course gaming. For me I prefer air cooling to water cooling, with cheaper water cooling systems there is a risk of leaks, also maintenance and monitoring as water does not mix with a pc system, but for the ultra over-clocking enthusiast the case accommodates any water solution, with large radiators and mega graphics cards in SLI, as well as air and the Noctua seems to be the best air cooler.and performs exactly as required for good over-clocking. The Noctua actually look quite stylish, an industrial and functional look, with the right LEDS, can make it look as good as any water cooling solution.

hey CreativeTiger :) I am in the same situation as you was. I have the fractal design r5, i7 6700k and the asus z170 mobo. The problem is that i cant choose the cpu cooler. I have HyperX Savage 2666 mhz cl13 2x8 gb ram, and they are 1.35 volt. They are 34,5 mm tall and noctua say that it only support 32 mm tall ram with a dual fan setup. I got the hyperx savage 30% off so i dont want to return them to get low profile ram. I want low profile ram because i want a noctua nh d15. I see that you have a noctua nh d15 and trident z ram that are not low profile ram, how did you do it? Did you move the fan up a bit or did you do it in another way? I cant wait to build my pc, but i cant decide what cooler :/

Hi, its actually much easier to adjust than it may seem even watching from YouTube videos. The fans have a sprung clip mechanism and attach to the heat sink tower. They can be clipped at any position on the tower, so can be clipped as high as the width of the case allows.It can be seen repositioned in following article: http:// In my case there is sufficient clearance for the side panel to fit and Trident z s are taller ram with fins. They are 44mm tall, so close to 1 cm taller than yours and mine allow for fan fitted with 2 or 3mm clearance of ram and looks like over 1cm of clearance from side of case, so you'd have an extra 1 cm clearance.

Even though some comments say fins on ram aren't needed, I think they probably do have heat dispersion effects. Another advantage of using the air cooler with fans running close to the ram is that it also helps dissipate heat from the ram as well as cpu and this is especially useful if using fast ram.

Other alternatives include buying another fan of say 120mm instead of 140mm to fit on outside as air input to tower and of course use middle fan, as base of tower is designed to fit with large clearance over tall ram. It will also work with just the middle fan, but benchmarks show best performance with both. The Noctua fans are amongst the best in the world too in terms of performance and in running quiet. But as long as use middle fan could add any make for outer fan and Noctua too make a 120mm version. However the fitting of repositioning the fan is really easy, as the clip system allows attaching to any position on the tower and you will have no difficulty using with your ram in the Fractal Design case as it is a good width of case, works perfectly with the Noctua cooler.

Okay, i see:) You just moved the fan up with the tall ram you have:) I was going to buy the Nh D14 instead just because of the clearance problems, but you have now convinced me to go for the nh D15 :D Do you think moving the fan up makes the cpu to heat more because the fan is not where it should be or do you think it has minimal to none difference? Are you using the two 140mm fans on the D15 or are you using one 120mm and one 140mm? And by the way, can you tell me your'e specs and how you're fan setup is? I am intrested ;)

Yes, the fan is positioned just as securely higher up the cooling tower. The 140mm fan is a wider diameter than the base to top of tower fins, so moving it up still covers from bottom to a bit further over top. The greatest heat removal is from the middle fan. I’m using both original 140mm fans. seems earlier models had a 140 and a 120 read somewhere of a slight performance reduction due to different fan sizes, but still surpassed a single fan. The actual benchmarks using just the middle fan are also really impressive. But if going for the maximum cooling then adding the second fan helps and could be important if playing games highly over-clocked. However, the difference between 120 and 140 for second fan may be very small indeed. I don’t think there is any measurable difference for repositioning the outer fan though, or rather you’d need a laboratory standard test bench to detect any difference at all.

I was considering going for the offset model NH D15S, but on checking out specifications its basically a single fan version of the NH D15 with offset helping some sli set-ups and not having a second fan means no ram clearance issues, but also no option for a second fan. However this model gives one the option of using one or two fans and performance-wise this is the best.

This test review shows the differences in performance using 1 fan, 2 or the lower voltage lower fan speed low noise setting. I use the full voltage one for maximum performance and the noise is still ultra-low. It speeds up when you need it, so can be heard then but still not bad and reassuring it has an effect and on board monitoring shows it has an instant effect on temperatures. So I have set it for the turbo mode to go into full speed at 60 degrees, which is highly effective.

The specs of my rig are rather high, but I want it to last can’t afford another upgrade for a long time, hence why waiting for a graphics card. It remarkable how the 6700k on board graphics perform. I’ve upgraded after using laptops but they can’t compete with decent desktops desktop, so can’t utilise an earlier graphics card and rather save the cost until Pascal comes out. If gaming, the benchmarks if relying on integrated, are hit at 3D, but for 2D it is very good. Of course a discreet graphics card helps. Main specs are 6700K processor that works well at 4.4GHz and 4.5GHz and can run it at 4.6GHz. But as using integrated graphics felt should lower it to 4.4 GHz at least until I get a dedicated graphics card. The ram is Trident Z 32 GB (4x8GB) 3200 MHz (OC) further overclocked with less than 1 step increased latency at 3466 MHz CL 17 18 18 38. OS is run on a Samsung m.2 950 Pro, along with standard SanDisk ultra II SSD and a WD blue 1 TB HDD. My specs are for working with software that requires ram. For a gaming PC 16GB ram is more than ample, with the emphasis usually being on a good graphics card or cards.

At the moment I’ve 3 input fans, including Fractal Design one includes, plus a Be Quiet silent wings at the front and another at the base, the 2 Nocua cpu fans on the cooler and the Fractal Design output fan. I may add an LED fan somewhere, but set it at a lower speed simply because even the best LED fans are much nosier than the fans I’ve got, which are all quiet. The Fractal Design fans are surprisingly good and worth keeping and the Noctua fans are incredible in terms of both performance and quietness. The Noctua ones are best for high static pressure so next to the cooler and that’s where it’s essential to have the highest performance.

The following article http://www.bit-tech.net/hardware/cooling/2014/05/01/noctua-nh-d15-review/2 shows how small the difference is between one and two fans on the Noctua though and that is because a lot the heat dissipation is from the dual tower configuration of fins and the central fan does such a good job at transporting cooler air through. The second fan just takes it to the next level. This article suggests possibly as little as 1 degree C difference, but have read other reports that suggest 2 degrees, still very little, but if pushing the system then that 2 degrees is extra cooling is well worth having. It does all this super quiet, also having 2 fans gives a backup.

Noctua fans are also very durable so not likely to stop, but heat sink itself has a great effect. It still performs well long enough to realise and make adjustments to fix it, although you need at least one fan to funnel the air across the fins to be efficient. With water cooling if anything goes wrong the block offers almost no cooling action, whereas with a large heat sink as in Noctua and with fans competes well up to mid-range water cooling, but without any risk of leaks. I can see why the Noctua has such a high reputation amongst professionals for workstations and for gamers who can see the advantages of air cooling and concentrate on getting most out of their gaming. Also for the cost of moving to a higher end custom water cooling solution that would pay for a really top rated graphics card set-up. Getting the Noctua means its the best air cooling possible and one can then spend as much as they can afford on best graphics card or cards.:D
