Radeon 7950 weird overheating issue

Recently, when playing games (notable, rust) my MSI radeon 7950's fan begin to kick up much louder than normal, and after a while, my computer freezes up (Screen goes blank, audio contiues for a few more seconds, then goes off) then I have to restart my computer.

Running furmark causes this to happen in about one minute, with the temperatures steadily climbing up to 80C, which it will then shut itself off at.

The problem, is that 80C should not be a high enough temperature to cause it to fail, yet it acts like it's overheating when it is not.

I have played rust for weeks without this issue, and it only recently started doing this. I have taken the 7950 out, and cleaned out my computer, reseated the card and it's power connectors, but no difference.

Anybody have any ideas whats going on here?
 
What are you using to monitor the temperatures?

If the card has a sensor on the VRMs like my old Powercolor 7950 (RIP) --which was a monster overclocker but it died in a mining rig while undervolted and kept reasonably cool, you could see what 25 seconds of furmark is doing to the card's temperature in another area besides the core. It is probably overheating, but not where the sensor is.

MSI will RMA it np I'm sure. Powercolor did.

I used the AMD overdrive, speedfan, and GPU-Z, they all showed the same temps.

Running furmark, it shuts off just before reaching 80C at core, and the VRM showed 67C. It hasn't been overclocked at any point.
 
Hmm. That's a good cooler, it should be something like mid/low 60s at stock settings while gaming. Even 80 in Furmark at stock sounds hot to me. Maybe the cooler isn't mounted correctly?
 
Have you tried removing the GPU shroud to get all of the dust and debris out? I would try that and re-apply TIM as well. Ensure that the cooler is adequately cooling the VRM area as well.

I also agree that TF3 shouldn't hit 80C with vsync on, that sounds a bit high for TF3 from what I recall. (although I used the 580 lightning with TF3).
