I have a relatively new BFG Tech 7950 GT OC (replacement via RMA right before BFG Tech went under) that I thought was bad, but I remembered I had pulled it out around the same time my old display died, so I figured I'd throw it back in to see if it was actually the display giving out on me.
Well, it turns out it was partially the display. The card actually boots up and displays Ubuntu 12.04 Unity just fine, but it idles at ridiculous temperatures and then flat out dies when I try to do anything remotely graphics-related. I was getting anywhere between 80-86C readings just from idling in Unity.
I took the card out and reapplied some Dynex Silver I had lying around from ~5 years ago to see if that would help and it didn't do much at all.
My question is: Is the fan/heatsink combo on my GPU the only possible reason for these insanely high temperatures? Could it be another component on the graphics card giving out, or would I be pretty safe by purchasing a new fan/heatsink combo?
Is that overkill for just trying to get temperatures down into normal operating range? Would appreciate any recommendations. I'm not trying to overclock anything. I'd just like a working video card that won't bug out under load.
