eVGA Geforce FX 5900 Ultra running VERY hot
 
A while ago I gave my gf my old eVGA Geforce FX 5900 Ultra when I upgraded to a 7800 GT. It was running fine for a very long time but recently her system has begun to crash alot. At first we thought it was a driver issue and tried a number of different things that was suggested to use in the nvidia Linux forums(issue was happening on Linux but it happens on Win to, she just dosnt use win that often). What happens is that after running any 3D app on Linux or Windows the system just crashes. The card idles at about 67C and within 5min of running an app the card gets to 100C. We cleaned the card off and it didnt help at all. Should we try to replace the fan, or would replacing it with a 6600 or 6800 just be better? Do you think the card is damaged?

Thanks for your help!

I would check the contact and thermal paste...maybe the HSF got bumped and broke contact. Does the fan still turn at normal RPMs? It could be dying.

I tightend the screws for the heatsink on the card while we were cleaning it. Id check the RPM for the fan but I couldnt find where I get the current RPM for the card. Where do I find this?

Tightening sometimes helps but if contact has been broken it may not be a solution. Removing the sink and the thermal material and re-applying is the only way to establish a good thermal contact.
About RPMs, your fan has no RPM sensor so the simplist way is to just observe the fan and see if it is turning at a constant speed and not fluctuating or slowing down. If the bearings are going it will be making an odd noise. More than likely this is not the problem. The problem is either the thermal contact or the less wanted reason...the card is dying.
After replacing the thermal compound and temps drop some but not significantly you could do a temporary test and place a high output fan aimed directly on the card and see if temps drop. If temps drop you just need better cooling for the gpu and memory.
