Is 80c too hot?

[ArtG818]

I overcloked my card and everytime my card reaches 80c game freezes and crashes, before i had Nvidia GT 220 and that card would go 100c -_- and not crash or freeze

Did this OC include a voltage increase?

If not, your stock volts just aren't sufficient for your OC.

Either increase the voltage or back off the OC.



Also running at 100c continually is really bad for the card - despite the 'max recommendations'. It will shorten it's life considerably.

Aim for sub 90c

If 80c is under EXTREME gaming and your fan is on 100% I'd say your right on the line of to hot. Although most cards are rated to run about 100c or a little more, to me your just asking for the card to fail, and as pointed out it will defiantly shorten it's life.
