hi, i have the same problem every summer when the temp goes up and my room gets way too hot due to the wrong insulation in the loft above me. Basically my graphics card ends up overheating when i play a game for more than 30 mins and i have to switch off the pc and wait till it cools down a bit. Im sure its down to my case which isnt doing a very good job of cooling it and maybe some dust on the card, however i've cleaned the card and got most of the dust out as far as im aware. The cards a gainward nvidia 7800GS 512 and runs idle at about 56degrees and when in demanding games up to 75. Any advice/tips of what i need to do?
cheers
Ben
