Slowdown in frame rate... overheating!

Hey!

Okay, I am out of ideas. Ive tested my system from every angle regarding a frame rate slowdown in most games after playing 2 - 10 minutes. The nVidia nTune software says the card is running 72C idle and 101C (slows down frame rates in game) while palying the game.

Its a Gainward GeForce 7600GT 256MB. Factory settings, no overclocks.

Anyone have an idea why the card is doing this?
 
The fan is turning full speed. So don't know :S Anyone have any idea what I should attempt?

Everything looks perfectly in place, and fan is spinning.

How is your case cooling and have you given it a good dusting recently.

Maybe remove fan and reattach after using some as5, could be thermal compound getting old and not doing its job properly anymore.
 
Case cooling is decent. Certainly nothing has changed that badly for an increase to freaking 100C+....

I think you could be right with the Thermal part of things
 
How much thermal compound should be on the GPU itself?
 
get a zalman cooler. For about R300 it will bring the temps down to 30 idle, 45 under load. and it will be completely silent.

Just enough to thinly coat the gpu ie small dot of as5 and spread it around thinly (only use the stuff on my cpu's have not used it yet on a gpu though that will change today as my x1950xt is way way to toasty)
 
I opened the card up properly, put more thermal stuff on there... there was a lot all around the GPU and none on it.. so scraped it carefully and placed it onto the GPU itself.

Also opened the fan/heatsink combo on the card, think layer of dust inside the sink. Cleaned it out completely.. rebooted the sytem, for the first time ever overclocked the card by 25Mhz CPU and 30Mhz Memory clock, and the card now runs (overclocked) at 37C idle (from non overclocked 72C before) and max 46C running HL2 Episode 2.
 
Sounds like the cooler wasn't mounted properly if it made such a big difference. Well done on fixing the issue :-)

Lovely, i almost destroyed my card trying to get the dammed fan etc off so gave up with only minor damage (damned stripped screw).

Great to hear you came right though :D
