what's the deal with everyone having overheating problems with their C2D, is this mostly operator error or a serious issue with the processor itself..
More an issue with the stock HSF that comes with the C2D.
They have these ridiculously "hard to ensure they are in correctly" pin setup, that makes it sound like you broke the motherboard installing it. With 3rd party HSFs, there aren't as many problems, other than the forgetting to put thermal paste, or ensuring a proper seating of the HSF to CPU.
I know I had problems installing the stock HSF on my HTPC system. I hope Intel will rethink their HSF install setup soon.
