I am putting together a computer for a customer. I have a gigabyte 845G board w/ the built in intel graphics, used them many times in the past, they make great office machines. I got a p4 2.4A 533fsb w/ the prescott core, this is the 1st prescott i have ever used. I have tried the intel heatsink and one from compUSA w/ a copper base and 32cfm 80mm fan, AS 2 and 3, about this thing idles at about 55C. WTF?? Even the 2.6ghz 800fsb HT northwood i built would not reach these kinda temps at full load w/ the stock HS. Whats going on, did i get a bad chip, do the prescotts run this hot?? I need to get this computer up and running but i don't want to give it to my customer running that hot. Should i try and get another chip, or just buy a northwood?? Thanks for any advice you guys can give.
