How to decide on a case for air cooling (warning - pics) - Page 140

post #1391 of 2110
Well formulas and all that stuff aside being an hvac mechanic and with lots of do dads to play with my Antec P280 gives the same temps as a Cooler Master Half 922 and all its ventilation.
The Cooler Master has large fans and many extra spots for them which I entertained but the fact remains that the Antec P280 with a rear blow hole mod seems to do just as good here
Sure I have to have fans on the front and behind hard drives but no matter

I have to try the mid case fan thing, I could always remove the rear grill and rear exhaust fan, and place it in front of the hdd rack.

Too lazy to take pics, but my setup is as follows: Warning: Spoiler! (Click to show)
450
No side panel nor top fans...Haven't removed the rear grill yet, but will do so soon.
I'm not sure if removing the rear exhaust is a good idea with my top down flow cooler. (Noctua nh-c14)
Temps right now are good, folding for hours at 4.5ghz nets me a max 59c temp in the hottest core.

removal of the rear exhaust grid and fan does two things. removes restriction of exiting air and reduces
noise. the c14 is fine with the 120 bay fan. granted, if you have a hot GPU, the side panel (if accessable)
would be a plus factor.

No gpu yet, I will be getting a gtx670 in a couple of months...
I'll remove the grill and place the fan as a top intake, or a mid case fan.
I'll see what gives better cpu temps/noise levels.
Thanks for the insight.

come back with results of findings..

I have a C14 as well. I find it cooler for the CPU to use the top case fan as exhaust than intake. I've got two PWM version of the Gentle Typhoon A-15 which spins at 1850 RPM. I use them as top and rear exhaust. Keep them at low noise mode when the system is not under heavy load. I have a relatively negative case air pressure with only one intake fan at the lower front of my CM KN101 case.

However, due to my 2600K requires 1.48-49 vcore in offset mode for a 4.8 Ghz overclock, my CPU temp still gets over 85 C after 5 mins of prime 95. But with normal load, the system runs cool enough without stability issues. The CPU idles at 35 C with the room temp at 27 C. And when in games and normal load, CPU temp stays under 75 C most of the time.

Plus, I find the system runs cooler with the bottom fan removed from the C14, as it provides more clearance for cool air to flow from the bottom of the case towards the top exhaust fan.

I suppose that rotated fan on the C14 would mess with the whole wind tunnel effect. You might try putting an intake fan into your 5.25" drive bay. That really helped me out when I had a mid-tower.

Second that, best results I got with my 2600k and C-14 inside a cm 690 II was with two front intakes (one of them being a 5.25" 120mm fan pressure mounted with foam and pci slot covers removed, have yet to remove the rear grill, -and I keep the exhaust fan there too-)
I can do 4.7 @ 1.36 though, folding 100% load at 75c -fans set to lowest speed possible, quiet and cool!- (24 ambient)

EDIT: I use both fans on the C-14 and keep the cpu @ 4.5ghz for 24/7 folding, that way I stay at 57-61c, much better for my peace of mind.

Thanks for the advice guys. I've added a front intake fan in the 5.25" area and have been able to do folding 100% on the CPU at max temp of 71 C. That's like 4 C drop compared without the front intake fan installed. (I had the bottom HDD intake fan installed always before.)

Unluckily, I got a crappy 2600K unit which requires 1.4 Vcore to be stable at 4.6 Ghz. and 1.49 vcore to be stable at 4.8 Ghz. So i've decided to stay with the lower and cooler 4.6 Ghz configuration.

Well, what's your board and cooler?
Mine does 1.36v at 4.5ghz, folding 24/7 stable at 61c max. (I use a nh-c14, two front intakes, one rear exhaust, and a z68ma-d2h-b3 board).
Perhaps you can tweak your oc to further reduce vcore and temps, folding should be under 70c to be comfortable. At least for me...
