GTX280 temps & crashing

[digitaldreams]

Hi

My old card was a 8800GTX. Hot air blowing back into the fan was an issue, bodged with some post-it notes (directing all air out of the back). Even so when busy (Crysis) I had to speed up the fan to 80% using RivaTuner.

Now running the lovely GTX280. I was suprised to find the case was metal !, acting as a heatsink itself, especialy for the rear memory chips. Crysis very happy, yet again the card is too hot to touch (esp the back plate towards the rear). After 30mins or so of Crysis the PC blue screens (blames the Nvidia driver), Vista64 losing it's SP1 in the process ?!?!. The latest RivaTuner in use again, speeding up the fan. Crashes gone, noise levels up....

I can increase the case airflow to compensate to a 'small' extent. Yet again I find Nvidia running the fans at too low speed to keep noise levels down !. The rear 'memory sink' plate needs modifying (beefing up) to include heat sink vanes & the bars of the back exhaust vent need reducing/removing (did this to my 8800GTX). I'm not interested in SLI so spacing is not a problem.

How is yours running ?......

Regards

If you are overclocking your other components I would try them at stock settings and see if it still crashes, it sounds like the extra heat from the GPU is causing other components to get hotter which could be the source of instability rather than the cards themselves.

One thing I've learned with Vista is that due to its heavy GPU reliance graphic driver crashes (even ones blaming graphic driver) aren't necessarily fault of the graphics card or driver.

No overclocking at all. I've proved it was the card getting too hot & again default fan speeds too slow...I'm increasing case and video card fans slightly, then will consider modding the card metalwork....

Same thing, even with fan on 100%. Furmark takes about a minute to get to 100 degrees and keeps going! I had to shut it off manually. Not happy with this card at the moment, may send it back today

Do so and get a 4870 or 4850CF

Case fans upped to medium, card fan increased to 62%.....so far so good.

Warm on the back, but not too hot to touch....bit noisey now !
