Overheating (I assume)

[Nebzor]

My case has nice airflow, and this problem has only started recently (about 13 hours ago or so).

I have my BFG 7950GT overclocked as stated in sig, and it was pulling about 61 degrees in games (according to RivaTuner anyway). Seems a bit low to me but oh well, may have been anomalous.

Recently, if I play BF2142 on max settings, as has been perfectly fine before, my graphics card overheats (hits 77 degrees or so as highest spotted temperature), the screen will go blank, monitor says it's receiving no signal, and the sound will jutter. Only fixed with a reboot.

Even if I go to default clockspeeds, the problem still occurs. I've tried to set fans to 100% at all times, as noise isn't an issue. Even up from the stock 35% in performance 3d, I'm recieving no lower temperatures.

What could be causing this? I've given the fan on the GPU a good blow to clear dust, it all looks clean. I've tried everything I can think of so far, and nothing has helped. Any ideas?

Maybe the card has been damaged in some way from the OC. Is the heatsink on properly, no loose screws?

The only thing I can think of is reseating the heatsink with some AS5?

I hope it hasn't been damaged. If it has, will my life-time warranty still be cool?

I was thinking about buying and attaching an after-market cooler, devoiding the warranty. Obviously if the card is damaged I don't want to do that, though.

Opinions, anyone?

Not sure if the warranty will still be ok, I can't see how they'll be able to tell if you oc'd it or not, so I would say it should be ok.

Are the same temps being read in the NV control panel? 77c doesn't seem that bad to cause the card to shutdown.

Try re-seating it with some new thermal compound.

Try putting a couple of spare fans (if you have any?) blowing over gfx card surface, play BF for a bit and see how you go, no more issues then you know heat is source of the problem.

Unfortunately both of my spare fans are over in my dad's computer, agh.

I find it odd too. Ideally temps should be under 80 degrees, and they are, but that's the only thing that is changing and that's the only thing that's causing the freezes.

Post it back and tell them nothing of OC. The shops know the score so they will just bundle it back off and send you a new one
