nVidia ForceWare Vista Driver Blunder – Thermal Management? :: TweakTown
The graphics card managed to generate so much heat that it completely melted the plastic clips which attach the VGA water block to the card – a quick test with a cigarette lighter shows that the water block area which screws into the card is flammable, we must have got lucky there and avoided that catching on fire. It also got so hot that it melted the upper copper surface of the VGA block and imprinted the nVidia logo and parts of the GPU core information writing onto the water block base itself, as you can see above. On the reserve side of the water block (the side that doesn’t make contact with the GPU core), we saw discoloration of the copper surface – the surface even started to crack in areas suggesting that bizarre temperatures must have been reached at its peak. Basically, it was a scary sight – to think the graphics card allowed itself to reach such extreme temperatures, it was a blessing that PCB didn’t catch on fire and I hate to say, the entire and computer and possibly subsequently the desk and then house. There’s obviously a low chance of that happening but when you’re working with such high temperatures, anything is possible and cannot be left to chance.
