Optimizing airflow

post #1 of 7
Thread Starter 
here is a diagram of my current case fan directions (Cooler Master CM 690 II):





Yellows: intake ( 120mm front, 120mm bottom and 140mm side panel)
Reds: exhaust(120mm rear and 2 top)
Blue: CPU Cooler airflow direction

I want to know if you guys think this is the optimal airflow desigination of my fans. The CPU cooler (Xigmatech Dark Knight, AS 5 Thermal Paste) is on an AM2+ socket so it can only be facing NORTH or SOUTH (cant situate EAST or WEST)

Im asking because my CPU temps are a bit concerning to me. I have an overclocked AMD Phenom II x4 970 at 4.0 GHz on 1.450 VCore

Idle temp: 38-39
Load temp: 53-56

These temps seem to be a bit high and not responsive to the cooling that I have.

Is there anything I can do to improve cooling/airflow? I was thinking that maybe 2 top exhaust fans are not necessary and maybe I can switch the top fan that is closer to the front to a INTAKE FAN? would that help at all? Any thoughts or suggestions would be very appreciated. THANKS

Putting Mesh on the side of your case might help cool your PC. As apposed to sitting your case next to an air con

but your airflow should be fine. Just watch your CPU and GPU temps.

That card is sucking up most of the air from the lower half of the case. Are you getting high CPU temps?

Switching the side exhaust fan to intake might help.

Edit: I'm not sure if you just edited your post or if I missed the temps, but that seems fine to me

Get a pedestal case for a server/workstation. There's your airflow.

i think the problem is there's no cool air going towards the heatsink fan. i would try turning rear exhaust into an intake so that the cpu cooler gets fresh air from outside and leave the top coolers as exhaust. maybe try adding a fan to the drive bay? using the top fans as intakes would not help much in your situation because the heat heatsink fan would be pointing in the opposite direction thereby disrupting your air flow. main idea is to get fresh air to the cpu cooler.

ok ill try switching the rear fan from an exhaust to an intake and see if that makes any diff in my cpu temps.
