So I have a case with room for 2 120mm fans in the front and top, one for the side panel and back and I also have a hyper evo 212 with a cheap nautical 20$ fan that is pretty old on the the pulling end and a cheap cooler master on the other end pushing the hot air away and so all those spots but the top have cheap coolermaster fans that came in a four pack combo and just a cooler master and nautical fan on the cpu cooler. So the question is I just got 4 of these courgar turbine 120mm fans and wanted to know what spots would be best to switch out for these fans all help is appreciated thanks

Also I plan on gaming like arma 3, heroes and generals, dayz, bf2bc, and war thunder on high if that helps with anything also if you need links and specs I can post them if u ask thanks all help is greatly appreciated this is my first build so I'm not as experienced with this part

Frônt slots: 2x 120mm cooler master fans

Side panel: none the cooler master fan makes that part to loud

Exhaust: 1x 120 mm coolermaster fan

Top: none

Cpu cooler: 1x 120 mm coolermaster fan exhaust the air away from cooler (back)
1x 120mm nautical fan old and from a rig that was old about 4 years pulls in the air for cpu cooler (front)

I have the airflow coming in from the front of case and out the back

I'd put two on the hyper 212 evo in push/pull, then one on the front of the case, one on the back. Then use an old fan to make 2 in the front.

There's a bunch of different variables here, so I'll just state the basics. Your front and side should be pulling air in, the back and top should be pushing air out. As long as you keep them like this you should have fairly even airflow. If possible you should try and set up the exhaust fans to be slightly slower than the intake fans that way you keep a positive pressure on the inside of the case which helps to eliminate dead spots where no air is flowing.

2 fans in push/pull on that 212 EVO doesn't really do a lot.

Nice. Didn't think it would be that small of a difference, thanks for posting that.

Still, I think with 4 new fans, it will make a bigger difference having push/pull (albeit minimal) than using them as chassis fans, but that's debatable for sure.

Thanks guys I certainly love all your guys helpful input but I think I'm going to put two of the cougar vortex fans on the evo one on the front and on on the side then the rest will be the coolermaster fans but also do I want to remove the nautical fan (brown fan with tan frame) from the evo as the fAn that pushes air on the cpu cooler and have the turbine the one that pull the hot air off or what?

Is it a 'NOCTUA' fan? If so, those are usually very high quality fans.

There is no discernable advantage to having push/pull on a tower cooler such as a hyper212. In fact, it can often be a detriment. The push fan will push the air through that tower just fine by itself. Because of the nature of air being pushed, some of the air 'bleeds' out from the sides of the tower. This air bleed is what helps cool other motherboard components such as the VRMs which sit directly adjacent to the cpu. The draw from the pull fan eliminates this bleed, so while you may see a 1-2° cooler cpu, you are hindering any cooling breeze across the VRMs heatsink.

The stock hyper212 cm fan is quite good at what it does, and is easily equal to a Cougar Vortex in that capacity. The Cougars however make good case fans.

My recommendation is: 2x Cougars as top exhaust, set for lower rpm @900. 2x CM as front intake, set for higher rpm than exhaust, @1300rpm. 1x Cougar as rear exhaust, see same as top exhaust. Either 4th Cougar or stock hyper212 CM on the cpu cooler. Either way, with 3 exhausts and only 2 intakes, set any fan curves to have moderately lower exhaust speeds than intake speeds. This has the net effect of keeping dust down. I'd not use the side fan unless after tweaking fan settings you determine that the gpu is still too warm. Side fans usually have a detrimental affect on good case airflow, so while gpu temps are lower, everything else is higher

Then you have other issues.
I have the 212 PLUS, with the stock fan in the default push config, sitting on an i5-3570k.
Absolutely silent, under 100% load. CPU temp hovering around 65-68C.

The only way I hear that fan is to take the side panel off, and stick my head right inside the case.

Okay thanks I might try that idea but fan should I use for the push fan? And I guess if the stock evo fan could work I could take off my other build but I just don't know what fans I should use for the push

Depends. If that Noctua fan has like 7 or more fat, flat blades, I'd use that on the cpu cooler. Noctua fans are exceptionally quiet and very high quality. If the Noctua fan has like 5 or so blades that kinda look like a propeller more than a fan blade, those Noctuas are designed as high cfm case fans, so are not as good on a radiator like the 212evo . Goto Noctuas website. Take a look at the pictures there. While model numbers may have changed, the basic design hasn't, its just tweaked with some upgraded performance. So if it's 'S' type it'll work great as either rear exhaust of if you must, side intake, if it's 'F' or 'P' type it'll be best on the cpu cooler

Okay so my set up i will leave a cm on the exhaust of case the noctua on the evo pulling cool air on to it, 2x turbines for the front and one on the side panel, 1x turbine on top pulling out air and 1x cm pulling out air on top.
Its just hard to comtrol their speeds with bios since the majority of them are powered via cable splitter 3 pin
If you think this is a good set up or i should change just leave a comment i appreciate all your guys help it is really useful

Something is just not adding up. 2x intakes and 2x exhausts with a good fan on a good cpu cooler is more than enough for good temps even with a hot running 290x. Are there hdd cages in the way of the intakes? A rats nest of wiring? Are fan speeds equitable? Is the paste applied correctly for a hyper212? Is that Noctua fan the high cfm case fan 's' style or radiator 'f' or 'p' style? What voltage is cpu running at under load?

Okay so now my idle temps are 48c with two cougar fans on the cpu cooler, and the noctua fan as the exhaust on back of case I put the fan speed wire attachment for lower the noctua speeds down side I heard u guys saying the exhaust should be lower speed and two of the cougar fans as front case intake. But I have the two top and one side panel empty and no fans, it seems that those just make it louder and just heat up my system even more for what ever reason, I know it can get lower than this, also I have the front panel open to allow more air to be pulled in, I had this build going at lower temps before new fan and could max out games without ocing and still stay at 47-49 c it don't know why I can't anymore

1 Cougar on rear exhaust splitter with 1 Cougar on top-rear. 2x cougars on front intake splitter. Depending on what Noctua fan it is, either the Noctua or a CM on the Hyper212. Your idle temps with that cooler should be in the low 30's, leading me to believe that you have a bad paste job as well. If you could find the Noctua fan or even post a pic, that would be very helpful. A pic of your build looking through the side panel would also help.

You don't have enough exhaust, that's pretty much it. You're forcing a lot of air in but it has no where to go so you're just recirculating hot air. Also if you just plug fans directly to a power supply that's going to result in them running at top speed and thus being extremely loud.

So then what do I do cause I tried top out takes and back with side and fronts intakes but pc temps rose to about 52 c idle

That Noctua is a nf-p12. It's an excellent fan for the hyper212, but lousy as a case fan. The cougars are good radiator fans but better case fans.
Put just the Noctua on the Hyper212, push, cpu_fan.
2x cougars as intakes, splitter sys_fan1
2x cougars as top-rear, rear exhaust, splitter sys_fan2
Go into bios and enable all fans at performance/turbo speed
Test temps with reliable software, coretemp, speccy, realtemp
If temps @idle are @32, load @50, you are good
If temps still in 40's @idle suggest repaste

So I did the exact fan placement you suggested and even reapplied thermal and turned up system 1 and cpu fan speeds to 100% but still same temps at 47c idle I noticed when I shut the side panel it touches just ever so slightly the evo brass pipes don't know if that can be a problem or not.also In bios i can only control fan system one and cpu fan but not fan system two, but I noticed when I turned it up to 100% on sys 1 the rear fans got louder too, also between the exhaust fans and evo I noticed some heat there

AMD overdrive is for gpu isn't it? Also, you'll be better off using prime95 small fft, or Intel Burn in test to properly Heat your cpu since you repaste. Not sure how accurate msi bios is, I have yet to try mine (new mb) but so far it's reading 43, and prior on my Asus board it was 32. I would also try realtemp or coretemp. If speccy, hwmonitor, and one of those all say the same, then you'll know if bios is reading right. Some software will read the socket temps, outside the cpu, speccy, coretemp, realtemp all read the actual core temps.
1.36v sounds about right for your cpu at stock speeds and voltage.

September 9, 2014 11:38:33 AM

Okay then I should just be worrying about the cpu core temps most then
