Overheating problem

[dimebagstu]

A friend of mine (who works in PC World) fitted a new heatsink and cpu fan for me after my old cpu fan stopped working but now my cpu temperature is around 65C idle and when I use a heavy app (such as a video converter) the temp shoots up above 90C until my comp locks up. I have done loads of searches and asked in loads of forums but still can't find out why this is happening. I read that the problem may be dust but my friend gave the inside of my comp a good clean before fitting the new heatsink so it can't be that. I also read that the problem could be not enough (or too much) thermal grease was applied but I asked my friend about this and he seems positive that is not the problem. I have tried running my computer with the side taken off the case and it still gets just as hot. Does anyone have any more ideas? its a Celeron 2.6 if that helps. I have NOT overclocked it.

It's obvious that the heat from the CPU is just not getting transferred to the heatsink. 65°C at idle is NOT acceptable, and 90°C is just insane, even if you're in a desert. My advice is to take the heatsink off, clean off the old grease, and start over. Make SURE the grease is applied properly (a rice grain's worth, they say) and the heatsink is flat and level and attached properly. Make sure the fan is turning in the right direction... don't overlook anything at all!
There's also the possibility that your temp probes are way, way off, but I've heard of this happening primarily with AMD-based boards. It would depend on what the temps were before you got the new heatsink and fan.

either the heatsink/fan isnt sufficient enough or it was applied incorrectly.
basically you MIGHT need a new heatsink, but either way it will need to be reapplied.
