BleepingComputer.com: High Graphics Card Temperatures

I have a Sapphire ATI 5770 (Juniper XT) like this model (Newegg link) and for some reason it has some really high temperatures.

Idle: 50 C
Load: 85 C (under Mafia II, 1920x1080 no AA, 8x AF, high detail)

This was with no Overdrive and measured by the HWmonitor and Catalyst Control Center. With in mind, I decided to turn on Overdrive to manually set my fan speed. Running the fan at 60% at idle drops the temps to 50 C, and when I game I put the fan up to 85% to get load temps at 73 C.

I'm wondering what I can do to drop GPU temps? These temps occurred in my Antec 300 case with 1 back exhaust fan and 1 overhead fan (running at low, I've changed it to medium now). I run a Phenom II 965 BE and a Corsair CMPSU-650tx PSU (it has an overhead fan). I'm thinking that maybe some front 120mm fans and maybe a side exhaust fan might help.

I'm not sure about reapplying CPU paste because there is a plastic case that covers the entire video card.

The next thing I'm going to try is gaming with the case cover off to see if it's internal case heat build up.

Adding more cooling fans to the system case will increase the air flow, I have two cooling fans on my towers front panel, 3 out the back, one on the side blowing toward the processor cooling fan, North Bridge chip and video card.

The Video card has its own cooling fan, power supply has 2 fans, plus the processor cooling fan.

As long as your power supply can handle the demand, it never hurts to have as much air flow as possible.

As for removing that plastic cover on the video card, I am not sure what is holding it in place, so I can not make a recommendation to you as to whether it is a good idea or not.

Thanks for the information Bruce!

I have space for 2 front fans and 1 side fan, so I'll probably look to filling those spots up with some.

At this point manually setting the graphics card fan to run at 95-100% seems to keep temperatures in check, and I can deal with the noise so it's not an issue, but I consider it a kind of a temporary measure until I find some time to buy and install those fans.

Try set the fans to the max.

My AMD Phenom 9750 would run 72°C when I ran both Trend Micro antivirus & SuperAntiSpyWare at the same time. Added two Noctua NF-P12 fans, one sucking in through the side panel & one blowing out the back. Max temp dropped almost 10°C, much more than I expected. Best $45 I ever spent, and the Noctua's are so quiet that no one knows they are there.

Even after adding the two Noctua fans, Prime 95 would exceed 73° before I stopped the test. A Gemini Coolermaster made all the difference. Prime 95 now runs at 58-59°.
