Rehauling NZXT Evo Tempest Fan System

post #1 of 8
Thread Starter 
Hey guys,

At 4.2ghz, my case breaks 80c during prime95 tests. I figured I'd the cooling a bit with higher powered fans. Here is my current set up:

Note: I'm running a Noctua U12P SE2


Orientation: Primarily, I'm looking to cool the CPU. Thus, my areas of focus will be the exhausts and the heatsyn fans.

CPU Fans (120mm):
STOCK: 2x Noctua NF-P12 - 54cfm @ 20dBA
UPGRADE: 2x Scythe Slipstream 1200 - 69cfm @ 24dBa
+15 cfm, +4dBa

Case Fans (120mm sides, 140mm top):
STOCK REAR EXAUST: NZXT 1300 - 47cfm @ 25dBa
UPGRADE: Scythe Slipstream 1200 - 69cfm @ 24dBa
+19cfm, -1dBa

STOCK TOP EXHAUST: 2x NZXT 1300 - 63cfm @ 27dBa
UPGRADE: 2x Noiseblocker BlackSilenPro - 90cfm @ 27dBa
+27cfm, +0dBa

STOCK SIDE INTAKE: NZXT 1300 (LED) - 47cfm @ 25dBa
UPGRADE: ?

STOCK FRONT INTAKE: NZXT 1300 (LED) - 47cfm @ 25dBa
UPGRADE: ?

Questions
(1) I assume that all fans are controllable via voltage when Q-Fan is enabled in the mobo, correct?

(2) Anyone have any ideas for LED 120mm for the intakes?

I have found the following 120mm LEDs:
http://www.newegg.com/Product/Produc...82E16835209011
http://www.newegg.com/Product/Produc...82E16811999122

My only concern about the two is whether or not they are mobo controllable. Otherwise, if they just go full power, I'm looking at some incredible dBA.

Thanks as always,
Daniel

Empty the top hard drive cage, ziptie/tape a 120mm fan on the back end of it pointing at the CPU cooler, and have the CPU cooler go <----||<-----

Alternatively, replace the 3 intake fans with better ones.

I've thought about doing just that. Isn't there some sort of adapter that would allow a fan to be placed in the CD-Rom area? (its not the Hard drive area, thats set behind the fans)

There are indeed drive bay fans, some that take up two 5.25in drive bay slots, feel free to look around.


Also, before blaming it on the case, maybe your CPU heatsink isn't properly seated or your ambient temps are high? just a thought.

Though its possible, I wouldn't see any reason for that to be the case. I've overclocked the processor 50% and its required more than average Vcore to get there. 80c in Prime95 would seem proper, no?

Additionally, a better idea. Why NZXT doesn't do this stock is beyond me, but you can switch the IDE drives with the fans! Thus I can place the IDE drives on the bottom and the HD Cage/Fans on the middle and top. DUH!

Now its a matter of determining which 120mm LED fan to replace my intake case fans with... which is probably the most perplexign question here.

I thought I read somewhere that it's ideal to have the front fan towards the bottom than towards the top. Could this be why NZXT placed the front fans in this manner? Also, they help keep the HDs cool. But I understand the primary focus is to keep the CPU cool. BlackHole, did you notice a big difference in temps when moving your fan to the top as I saw in one of the pics that you posted?

Silverstone has some fans blowing in at the top. I've tried that and got better cooling, at least with the front top fan. YMMV.

Check my sig for fan comparisons.

The Noctua 140mm are the best - you can point their output pu, down or sideways. With sleeve bearing fans, they can go sideways and usually down without trouble. NZXT has some 140mm fans that people have said good things about.

Do shop around. Various vendors have various prices.
