480 or 5970?

Both 4890's get a bit hot,i have noticed when i minimise from a game Arma2 OA and go into the ccc it reads 103c and game was stuttering with frame rates dropping from between 50-60 down to 20,it started doing this about 2 weeks ago before then everything was fine,i have also give the cards and pc a good clean.
 
Lol, that's not 'a bit' hot. You need to sort out the temps, that's for sure. High temps aren't caused by dying GPUs afaik. Are you sure the fans spin correctly? Is it just one GPU reporting this high temps?
 
@ moment in idle
card 1 is 73c fan speed 47%
card 2 is 60c fan speed 41%
which is a suprise as card 2 use to run hotter than card 1
 
Interesting, can you take one of them out and see if you get any performance/noise/temperature issues? Do it with the other next, maybe a cooler is defective on one of them.
 
I don't think the GTX 480 is a good choice if you're bothered about heat 8-).

Btw, you probably won't see much of a performance increase either so it's your money but I think you'd be wasting 400 pounds for nothing.

5890 best card thou, specially if you're worried about heat.
 
well i think he has a good reason to be worried about heat.

card 1's idle temps are way to high, and > 100C is never a good thing

even an overclocked GTX480 dont get that high.

it sounds like ur fan isn't working correctly, u could try to ram up the fan speed on that card and see if it cools properly, if it doesn't make much difference, u know the fan aint working right
 
Clean out your fans, they're probably clogged with dust. A 5970 will be more than an upgrade than a GTX480. 4890 crossfire will be around the same performance as a GTX480.
