Default Hot cpu

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

:\ Maybe its a bad sensor? If its easy enough, swith the chips to see if other chip reads like that, after you see if HSF is problem.

I have one of the old slot 1 cpu's. I put thermal paste on mine. It didn't hurt anything. just make sure the heat sink is firmly clipped down on the one thats running hot. You shouldn't be able to see light through the middle where the heatsink touches the cpu die. I have seen heatsinks with duel fans.
