Socket 775 P4 CPU's tend to run hot.
2 of the biggest causes are the junk thermal compond Itel supplies & the heatsink not being fastened down properly.
If you have a Radio Shack or electronics supply shop handy get a tube of Silicon Heatsink Compund.
Unplug the computer & open the case
Take a straight blade screw driver & turn each of the CPU hold downs counterclockwise.
Lift up on each nold down & then remove the heatsink
Clean the old heatsink paste off of the CPU & heatsink with a piece of paper towel moistened with rubbing alcohol
Make sure the heatsink isn't clogged up wuth dusy/dirt
Put a VERY thin coat of thermal paste on the CPU
While gently pulling up on the CPU mounting pins turn them clockwise until the screw diver slot points out away from the heatsink
Position the heatsink on the motherboard making sure all 4 mounts are in the holes
Hold the center of the fan down with one hand while pressing down on a mount pin until it clicks
The idea is to keep the heatsink from lifting off of the CPU while pushing the pins
Push the retainer pins down in a X pattern
Don't forget to plug the fan back in if you have disconnected it
If the heatsink is mounted right your temps should be lower
As the computer is used over a couple of weeks the tem should drop another 4-5C as the thermal paste "cures" .
