I have seen a few Intel P4s giving heat problems, I nearly cracked up when the one dude said he got Intel because he heard that AMD ran hot.... Well I was thinking I could either laugh or rip his head off and dance around the room with it. Anyway they ended up spending about 1K for a water cooler, foolish earth creatures.... (not from me BTW)
Other person bought one for a recording studio, only problem is he was getting complaints from the people at airport that they could not hear the planes land because the CPU fan was too loud, he was a bit ticked off when I told him that the 939 system in front of him he was in fact on and running, and it did not run hot, and it could up-grade to dual core (Which Intel could not do at the time) - Again the same old story, ohhh don't buy AMD they run hot, you can still phone computer shops and some berk will tell you that
