I have 3 GPU miners each with a single 7950 card. One of the cards suddenly is going extremely high in temperature reaching cutoff within a minute. Fan speed shows as if it's spinning at normal rate. This is my first GPU issue since I started mining a couple of months ago. Can anyone tell me what I should look for?

I have since turned it down too 750MHz GPU speed and temps are steady at 87C - and this thing is doing as much hash rate as a USB block erupter, which is a shame.

Any help is appreciated.

When you physically look at the fans - are they both spinning full speed?

I'll see it today when I'm at the site but thanks for the pointer, sensor could say one thing and fan could be off. Are they easy to find and replace?

I had a 7970 that suddenly began to run at much higher temps - turned out one of the fans had stopped turning - see here for the various suggestions from the community...

It turned out to be one of my high cfm fan controller going bad and stopped a case fan that was directly pushing air onto the card. This was also at night time so there was no air conditioning, hence temp jump. I removed the controller and all is back to normal but noisy as hell because this fan does 260cfm and sounds like a vacuum cleaner going.

My suggestion: quit running that card.
My question: how much more do you pay on energy compared to your BTC reward?

I have free power... or say included in rent so whatever.
