From my subject line, inside of my 932 HAF case I have a BFG GeForce 9800 GX2 graphics card. Cable management is great inside the HAF case, so, nothing is restricting my air flow.
As you probably know, the GX2 is like two GPU's sandwiched into one "brick", and, it can generate quite a bit of heat. The HAF case has four massive fans. The front and the side fans are intake fans, blowing air into the case. The rear and ceiling/ roof fans are exhaust, sucking the air out.
The ambient temp for me is around 20 to 25C. When I check the temps on my GX2, they're usually around the high 60'sC when system is idle. The fan speed is around 45%. I've seen posts around the 'Net with people claiming to get in the 40's to mid 50's with a GX2 when idle. I use EVGA Precision to monitor my GX2 card. And, I know, I can always increase my fan speed using this tool.
But shouldn't I be getting lower idling temps? This GX2 is a brand new card; I just had it RMA'd recently and this is the new one now in my system.
I came across a post over on Overclock.net about someone who reversed the direction of their side case fan to help with temps on a GX2; here's the link:
They seem to think that turning the side case fan from an intake to an exhaust will help, because the GX2 has those side fins that blow out heated air, and if the side case fan is blowing in, then it kind of defeats the purpose when these two "air flows" meet. Do you think there's anything to this? Should I try reversing the direction of my side case fan?
Or how about this: The HAF case's manual shows that if you want you can replace the fans that the case comes with with multiple fans instead of the "big" ones it comes with. What do you think of replacing the 230mm side case fan with four 120mm fans?
I just think I should be getting lower temps for my GX2: It's brand new, my ambient temps aren't too high, I've got good cable management for good air-flow from front to back, and the letters "HAF" stand for High Air Flow.
Please let me know what you think. Should I try the side fan direction reversal thing, from intake to exhaust? Replace the one 230mm fan with four 120mm fans?
Thanks for your input!
