its all about air circulation , if you have a small fan in front u want a bigger one at the back and if possible at the side to chuck warm air out , blow holes are handy to , to reduce case temp and ultimately lower ur cpu temp a few degrees , also messy cables can restrict airflow flat stock cables are a big no no unless you spend time and thread em underneath your mobo tray ( if u have one ). ultimitly if all fails stick a zalman on it lol

i have a thermal take shark and a x2 4800 and never seen it get above 54c fully loaded

also small things like decent thermal compound etc etc

hope this is somewaht informative

by the way pentiums always run hot a friend of mine has exactly the same problem, ive had it and im pretty sure the majority of people with p4s have had it but thats why i stick with amd now cause there just better lol
