Hot cpu

[gth]

Hi, I have an old PII machine with dual slot 1 processors. They have the type of heat sinks with the snap lever. They came from the computer manufacturer without paste.

Should these processors and heat sinks have thermal paste between them?


Also, one of the processors was running at 80 degress C and the other at 29 degrees C. I noticed that the hot processor cooling fan is speeding up and slowing down constantly while the cool one runs at a steady speed.

Would this be normal if there is no load on the second processor?

Think I'll swap the fans to see it if the situation reverses and replace the fan if necessary.


Any comments or suggestions are appreciated. Thanks, TH

If that machine has run this long without thermal paste I wouldn't go and worry about it now. The fans may need replaced once in awhile. I'm sure that over the years they've done their fair share. Retire them and get some new ones.

Hi, Thanks for the reply. I swapped the fans and the intermittent one is continuing to speed up and slow down so I'll just get two new ones. The cpus are running at 58 degrees C now. I think the one with the bad fan on it now doesn't have much load on it so its running cooler. I appreciate your quick response. Thanks,TH

I doubt that old board had temp control for the fans. sounds more like the bearings are dying on the fan.
