GPU temp is EXTREMELY HIGH!

post #1 of 10
Thread Starter 
I'll make this short and sweet. I have owned a BFG tech 7800GT for over 2 years now. I just checked my gpu temp using a nvidia monitor program and the IDLE temp was 67C. I played a game of counter strike and the temp went up to 101C!!

Now, lets go back a month, I turned my computer on one day and my gpu fan made like a winding-down sound. I kept the PC on for like 3 minutes then I shut it off. I turned it back on and the sound was gone.

It has done that every day for a month now. I don't have the money to fix it right now.

What can I do? I can play games perfectly fine; no artifacts or anything and no freezing. Is this a sensor that has gone bad or what?

Should I take off the GPU heatsink and apply some AS5 to the chip? How do I do that; could you point me to an article?

Thanks for your help

Nathan


P.S. The ambient temp in my room is 72F. Are these temps within the factory operating temps?

Have you adjusted the fan speed with rivatuner? Is the cooler clogged with dust?

I blew the GPU fan out with a can of compressed air a month ago; that's when the fan started making noise when I would turn on the PC. However, like i said all i have to do is shut the pc off, then the noise is gone. I just adjusted the GPU fan to max speed and the IDLE temp is 65C. Someone told me that the 7800series max temp is 115C..true?

Would I benefit from putting some AS5 on the chip? How would I take off the heatsink/fan on a 7800 GT?

Thanks,

Nathan

Did the fan on the GPU heatsink die?

Usually, it's these cheap 40x40x10mm fans that die on cards. It could be possible that the fan bearings or sleeve bearing seized up. That could explain the sound you had once heard.

Typically, the heatsink is attached via black push-pins that have tiny springs or a double pop'er plastic plunger fork.

You will need to free these from the back side of the GPU card with needle-nose plyers.

Take off the heatsink and re-apply the cooler with some TX-2, AC5 or whatever you got, anything will be better than stock...

I doubt it reached 115C. Maybe you are getting Fahrenheit and Celsius mixed up? 115C is probably enough to burn your computer and burn your graphics card to a crisp as most CPUs can only withstand up 70-80C before frying.
