7950 GX2 overheating?

I have a GF 7950 GX2 which is around 3 years old. Started to get problems with the PC just freezing the past few days, tested my memory with Memtest and had a dodgy stick which i removed, thinking that would solve my problem.

The problem persisted and it wouldn't let me change the display rate without crashing and i was getting a dozen or so random flashing pixels. The only way i could get my PC to boot is by booting in safe mode and disabling the drivers for the card, otherwise it kept crashing just before or after windows login.

I think it may be overheating, since this morning i booted up and enabled the drivers and managed to boot but the temp when i am just browsing is 70c with fan on 40%, if i put it up to 70% then it brings it down to 62c.

Is my card knackered?
 
I have taken it out and blown the dust out, might need a better clean but surely the card can handle much higher temps? without causing issues.
 
Well know issue. Take it apart and wash the heatsink, it'll be full of dust. Then clean the cards with some IPA and on the HSF. Use a quality TIM and go from there.
 
Open up the driver software and there should be a max shutdown temp. This should be 100+ however, and you shouldn't get anywhere near it unless your fan dies or your card is seriously caked in dust.
 
Seems to be running ok while under normal load now with a temp of 65c on 40% fan speed, is that to high or ok? is it normal for Furmark to take the temp to 96c in a few minutes on the stability test and crash this card? or do i have a problem with the card.

I have just bought a 2nd hand Radeon 4850 HD and was going to put this 7950 gx2 on eBay but dont' want to if it isn't working right.
 
Furmark is a stresstest program, designed to put your card to the absolute limits.

It shouldn't crash, so theres definitely an issue.....but if it doesn't happen outside of Furmark, I wouldn't worry about it myself.
 
Looking at Furmark i see it gives the temp for GPU1 and GPU2, when running the stabilty test GPU1 reaches 98c while GPU2 remains around 70c, i know the card with the fan facing inwards will get hotter but a 30c difference?
