hi, this is my first post :flowers:

i have a P4 775 cpu, and it overheats when i play intense games. my graphics card is a 8600GT, so i assume that's fine.

i did a heat test , and when playing, my cpu goes to like 77 degrees. i assume thats centgrade ( sorry, i can't spell :thumbsup: )

i cleanes my cpu case and fan, and it went down to like 65 degrees.

should i invest in a better fan, or lash out on a new cpu ?

Hi, was the temp read in the bois or through another program? If this was done through the bios it may be a bit high. I have gone through this myself: http://www.bleepingcomputer.com/forums/ind...p;#entry1047592

But if you have cleared out the dust and it is no longer an issue it may be safe. Tower fans may also help, one front and back ect.

Once you find your cpu, click the sSpec Number in the right hand cloumn,
for example

http://processorfinder.intel.com/details.aspx?sSpec=SL94V

The thermal spec of 69C is what I call redline, they start to burn up at theses temps

No. Try not. Do... or do not. There is no try.

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" .

Edited to fix a flock of typo's !
