High temps on the GPU's

I have dual GTX470's and they are running pretty hot! At idle GPU 1 averages about 50-55 and GPU 2 about 40. I have been experiencing increasing temps just preparing to play a game, with the fans reaching maximum speed 3-4mins in. I just loaded Halflife2 set it on medium detail settings and low res and within 3 mins I could tell by the fans that the GPU's were getting too hot. When I exited, GPU 1 was reading 89c! Bare in mind this is all in the space of 5 minutes from idle.

I'm sure this can't be right. I don't want to damage them. SLI is enabled, should I turn this off to test? Indecently I have the machine placed within a shelf (open front and vent to top/side. Would that make such a dramatic difference? Again I haven't taken the machine out of this to test, but I will. I had a look in BIOS, but not sure what I should be looking for and obviously don't want to mess about with that too much.

Any feedback would be welcome.

470's can happily run into the high 90's and stay there. The default fan profile will not even start to ramp the fan up intil you get to mid 80's.

Wow happily run into the high 90's. Okay thanks Gorman & Maestro, I'll carry on, but just keep a watchful eye...better to be safe....

Whilst *they can* do that without damage, I would personally advice manually cranking up the fan speed to about 60% on the cards - this will keep them within a healthier zone in my opinion.

Well if the default fan profile is good enough for Nvidia, its good enough for me.

I would no more suggest a blanket alteration to the default fan profile on a gpu than i would the radiator fan on my car.

Yeah you can't expect cool temperature from a GTX470/480 it's just the way they were (badly) designed, they're still going to function perfectly well though up to about 100*C.

behave yourself, they are great cards. a little less regurgitating of incorrect info needed around here i think!

Just been testing the performance over the last 2 hours playing crysis. Got up to 93c, an I gotta say, they run it pretty sweet. Thnx for your reassurance, I would have probably baulked at playing it otherwise.

Right I've just been playing crysis at high settings & at resolution 1600 x 1200. About 30mins in the screen went blank, sound was still there though, so obviously a error with the video signal. As I couldn't exit from the game or get a picture (turned screen on and off to no avail) I had to press the restart button. I could hear Windows had loaded, but the screen was still blank, simply said no signal when I turned off and on the screen. I then swapped the DVI cable from GPU 1 and put it into GPU 2 and the screen came back to life. When I checked device manager it was just showing one GTX470. Also in Nvidia control panel just the one GPU. I then shutdown the PC, turned it off at the mains, swapped the DVI back into GPU 1 and turned the whole system back on. Now the screen is back and other card has reappeared in device manager.

So what does this sound like? A driver issue - I'm just updating the latest driver now to test. Or something more critical. Could it be the GPU getting too hot and cutting out? The sound still being there makes me think it could be. Any suggestions would be welcome.

ok let us know what the result is when you are running the 262 drivers. One of the GPU's may be overheating, but in my eyes thats unlikely.

Crysis and SLI fail = infamous

oh the hilarity!

I should have said SLI/Crossfire fail.

Thats if you can get it to launch on a Radeon system :p

Thanks for that guys. Well I haven't had the guts to fire up crysis again, but I will now, so I'll let you know the outcome in an hour or so

1 hour and 5 mins on Crysis, no crashes. Guess we're in business again (famous last words, touch wood). Could have been the drivers, I've given the machine a little more breathing space above it too. Rest assured any more probs I'll be back.
