Temp Too High

trexmkii · 10-11-2009, 11:38 AM

Hi,
I have a Radeon HD 3870 512 DDR4 card.
It's running too hot!!!
According to GPU-Z 0.3.5 my temp is 57 C when the card is idle!!!!
I just got Operation Flashpoint 2 and the game keeps freezing!!!
GPU-Z 0.3.5 recorded GPU temp. 95 C when my PC froze but the game worked perfect until it froze. Also, GTA IV never froze before and now it's freezing up.
The strange thing is that GPU-Z is showing the the fan is only working at 60% ever though the temp. is 95 C.
PC Specs:
AMD Athlon 64 X2 6400+
Gigabyte GA-MA790X-DS4
2GB Kingston DDR2 1033Mhz
Sapphire Radeon HD 3870 512MB DDR4
Western Digital 500GB 7200RPM 16MB
Huntkey V-Power 550W

Is there any way to disable the smart fan function of my GPU and let it run on 100% fan speed?

Use riva tuner and set it manually to 100. Also make sure you have decent case cooling as well.

Just offhand , that power supply is junk. You should really be running a quality unit with that card 600w+. Bad power supplies can also cause components to heat up.

I tried riva and succesfully set the fan to 100% and droped the max temp down to 82 C but games are still freezing up. I think maybe it's not the GPU that's the problem. I suspect it has something to do with my sound card.

No it's that power supply , change it out to a much better unit , sound wouldn't have anything to do with it.
