Hi,

I'd like to build a "silent" system with the following components:

- ASUS ROG MAXIMUS VIII HERO ATX Z170 USB 3.1 Motherboard
- Intel i7-6700K Processor LG1151 Skylake
- G.SKILL TridentZ Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Memory F4-3200C16Q-32GTZB
- Samsung 951 M.2 AHCI 256GB SSD (for OS)
- Scythe Kotetsu
- Fractal R5
- Gigabyte GTX950 Extreme
- EVGA superNOVA 650 P2 or other silent one?

Does anyone know if the Scythe Kotetsu has enough ram clearance for this G.Skill TridentZ DDR4 3200 memory as it has heatspreaders? Otherwise I thought of the Scythe Mugen MAX, which is placed asymmetrical.

Thank you in advance for your help.
 
Solution
i may have gotten an old kotetsu as i ordered from australia and didn't walk into a big electronics retailer for fresh stock, which is my preference. once i removed one set of the washers though it fits perfectly.

i left the stock kotetsu fan on there. as i said it's inaudible on my 6700k @1 meter inside fd r5 no window.

the noctua nh-d15s is a good choice.

http://www.silentpcreview.com/article1408-page6.html (and the whole article, which goes into immense depth about their testing methodology in their anechoic chamber, the whole site is gold really) is what helped inform my cpu cooler choice. i don't plan on overclocking so was happy with the single fan cooler. if you plan on overclocking i'd pick from the dual fan (noctua 15 is...

Thank you for your PSU recommendation, but unfortunately I can't buy it anywhere in Belgium.
I have a Corsair AX650 in another build, which I find silent, but it's no longer available. I can find Seasonic Prime 650W Titanium.

Would the Seasonic Prime 650W Titanium be better quality? And do you know of a near silent GPU (with Displayport)?
 
you usually won't be able to hear the PSU out of the R5 if you don't use an exceptional loud PSU. if you really want a silent but actively cooled PSU, go with a BeQuiet Dark Power.
the CPU cooler is listed with 28dba, I think you should be fine. if you realize it's too loud, buy a 120mm PWM Noctua/Phanteks fan to replace it. if you plan on OC your CPU I would however go with another CPU cooler, BeQuiet comes to mind again, so does Phanteks, Cyriog & Noctua
any specific reason for the TridentZ? bcs Ripjaws will just do as fine and aren't so problematic with CPU coolers

GPUs produce noise when under load.
I'd go with a GTX1060/70, they got this zero-fan-mode up to 60°C

Thanks for the suggestions.
I have a completely silent build now, based on Sandybridge i7 with Corsair AX650 PSU (silent, Noiseblocker M12-S2 fans (silent) and Thermalright HR-02 Macho (the TY-140 has a bit of hum but you have to listen to hear it) and I 'm looking to build a second system that is as silent.

No preference for memory. A silent PSU (Corsair AX650 equivalent ?), CPU cooler and GPU are more important to me.

The GTX1060 seems a good idea, thanks.
 


I got a XFX 650W bronze and it's literally unaudible. so I wouldn't worry about the PSU too much, only the seasonic S12II series seems to, in some cases, have some weird fan control. but you're aiming higher anyway.
as said, a BeQuiet Dark Power is expensive but uses silent wings 2 fans, and there's no fan as silent as a silent wings 2 fan
I personally don't like the idea of passively cooled PSUs.

I don't like passively cooled PSU either, that's why I find the Corsair AX650 so good. The SeaSonic Platinum Series 660 I see know also comes with a fan, and with a fan controller apparently, and is more reasonably priced.

Whether or not that build will be silent will depend on the gtx950 fan quality or coil whine (I don't know anything about 950s as I primarily research 980 1070 1080). My guess is it will be silent as a lot of the lower end graphics cards just don't create much heat as they're much lower powered.

Corsair rm550x is more than enough for that build and runs completely fanless I.e. Silent under the loads that setup will use. (Under normal loads, stress testing doesn't really count as you only do it for 1 hour or whatever and then never again). It's a favourite at spcr right now because of this, as well as being cheap and widely available.

The kotetsu easily clears that ram and -probably every single other ram on the market. Gskill tridentz seem to be the best ddr4 at the moment, I just got 32gb set myself and besides the stupid red paint job on them in very happy with them :) It has really good clearance. I found that I need to remove one of the sets of washers that came with the kotetsu for it to mount properly on z170 sky lake asus mobo (viii hero) but other than that it's amazingly quiet and looks good and also gets close to the best temps available (until you move to water)

Overall without any fiddling your build should run completely silently. You will want to use asus' excellent fan control either in mobo or their bundled fan xpert software to keep the case fans and cpu fans to around 500 rpm until 70' Celsius cpu temp. At 500rpm the stock fans that come in the fd r5 are completely silent from 1 metre.. Of course if you connect the case fans to the case fan controller and not to the motherboard you can use fractals slow medium fast switch to control the speed of the fans manually, generally the slow speed which is inaudible still creates amazing air flow and temps in this case, such is the excellence of its design.

Hope that helps, sorry about taking a little while to respond :)

Thanks for your feedback! it's really helpful.

I think I'll go for the G.Skill Ripjaws version, as it's the same as the TridentZ, I think, and less expensive here.

As for the CPU cooler I was thinking of the Noctua NH-D15S as its fan seems to run quieter than that of the Kotetsu. Did you replace the stock fan? Also, I thought Scythe included new washers for the Skylake cpu?

I think I'll keep the Corsair AX650 for my new build and use the Corsair RM550x in my old build. I read that the old AX version is still better than the new RM version.

I'll have to experience the Fractal R5 case fans myself. Some say they're silent, some say not. I now have Noiseblocker M12-S2 fans and they're really silent!

the fractal r5 fans are very good but i find above 600-700rpm i can hear a combined acoustic hum, not high pitched, not altogether unpleasant, but definitely audible above 600-700rpm. i bought a third gp-14 fan (the fan the r5s come with) and have all three case fans connected to fan headers on my z170 hero viii, and have them set to lowest rpms which is under 600. i'm sure if you want to replace them fans are so cheap that it won't hurt too much :)
 
Solution



the Scythe Mugen Max is a great cooler, installed it in a friend's case. I myself currently use a Mugen 4.
Scythe fans don't get too loud when under heavy load but you can definitely hear them. but I don't yet have my silent case (should arrive next week, I can tell you if I'm able to hear the Mugen then). Overall there are surely quieter coolers out there, at least in idle state.
Phanteks coolers should be pretty silent as well, or, as one test suggested, getting a Noctua Cooler but replacing the Noctua with a Phanteks fan (I wouldn't have even thought about that, I mean which kind of maniac person replaces a Noctua fan) which should result in lower noise and lower temp according to the test.
