Dear CPU Scorekeeper

I have a Pentium III 600E and it is running at 68 C or 150 F. I have a cooler running at 4700 rpm.

Isn't the temperature too high? Can it burn my processor? Are these numbers OK?

I doubt it `cause I have a Pentium III 500 at 43 C, but I'll be glad to know your opinion about it.

See the questionCPU Scorekeeper Responds

As you can find on our Pentium-III page, the maximum recommended CPU temperature for a Pentium-III 600E will differ depending on whether it is connected to the motherboard by SECC2 (Slot 1) or FC-PGA (socket 370). The maximum operating temperature of the original and more cooling-efficient Slot-1 version is approximately 75 Celsius, while the Socket-370 chip temperature should remain below 85 C.

Your CPU temperature is within the normal operating limit for both types. However, if you are concerned about reducing its temperature, consider adding an additional system case fan or running a software cooler.

Note that all our Intel and AMD CPU pages list the respective maximum recommended operating temperatures, where available.  For more information about CPU and computer cooling, check out the Heat Sink Guide.
