What to do on 9600GSO overheating?

[ArchDuo]

Hey guys - my xFx 9600GSO is having overheating issues. I have used this card for more then 1.5 years without any flaws - overclocked it to 680MHz and had an awesome performance boost those days. Recently it's having overheating issues. The GPU idle temperature is about 55-57 degree and when giving full load on it (crysis warhead benchmarking....OCCT and FURMARK stress check) - the temp reaches 90+.

I have cleaned the heat-sink and the Fan - and applied Arctic Silver 5 thermal paste before reassembling the heat-sink. Still the overheating occurs. Please guys tell me what to do.

My PC Configuration is -

Processor - Intel Core 2 Quad Q8400 @ 2.66GHz
Motherboard - ECS P45T-A
RAM - 8.0GB DDR2 800Mhz
HDD - 320GB + 80GB SATA
Graphics Card - xFX GeForce 9600GSO 768MB gDDR3 with nVidia Forceware V258.96

thanks in advance........

i have a chesis with 2 intake and 2 exhaust fans with a very decent airflow - yet it's overheating!

90C under Furmark isn't really so bad... The real test of a case's airflow is to open the case and aim a house fan at it, then see if the temps are any different. If they drop, then you have airflow issues.

Any chance you live some place hot and don't have air-conditioning?

Yah....i live in BD where the weather is a bit hot now - and yah i dont have AC - but i used this card in summer even - it was not hot that time......

That's what I'm thinking CT... It might help to go back to stock clock speeds, but the card may have begun to get a little wear and tear that wouldn't be affected by slowing it down a little.

And as I suspected, such an idle temp is more common in hotter climates. I'd bet that on a cool night, the idle temp would drop into the mid-40's.
