Since the fan was not working, why would the question be about too much heat? There was a clear failure that needed fixing.
I used nvidia 9400GT previously which was gone a year ago because of Heating problem. 2 Capacitors were open from top and a chip was fried.
And after a year my friend gave me his gfx card because he was not using it.
It worked for a day.. next day morning pc was normal for an hour and then my screen was gone, so i checked gfx card .. it was very hot. fan of that card is gone .. I dont know what is causing problem..I lost 2 Graphics cards... Is there a problem with my mother board?
