It will very much depend on exactly which type of CPU you have, even possibly down to the exact version number in my experiance.
I have an AMD 400 i think it is and it's over clocked to about 575 MHz.
I have most recently been using it as a server and even under 100% CPU load the heatsink does not even get warm. I can even run for a limited period with no heatsink.
And then the Cyrix 300 or what ever it was that was in there before would get quite hot just idling on windows 98.
On your CPU inspect the heatsink for any dust between the cooling fins this can make a huge difference to how hot it will get.
I've seen increases of 10 to 20 celsius (18 to 36 FAHRENHEIT) with a dusty heatsink. Thats just with normal use, without any high CPU usage programmes.
If you CPU is getting hotter than it should do your system can start to become unstable and some programmes can crash or lock-up and you can start to get Data loss.
If it's easy to un-screw or remove the cooling fan without removing the heatsink do so.
Make sure you remove the power lead from your mains power source before hand.
Make a note which way round the fan is before you remove ie. back and front say by the location of the inner frame that holds the fan motor ( on the one i have here at the moment the 4 spokes of the frame are nearest the heatsink for example) this way the air flow direction will be the same when it goes back on and take note of the position of where the wires enter so it goes back in exactly the same way.
Brush any dust out between the cooling fins with a small paint brush. Make sure you get the bristles of the brush right to the bottom of the fins so all the dust is removed. Then brush any dust off your cooling fan also and put it back on being cafefull not to over tighten the screws.
This can make a huge difference.
Where i work it's quite a dusty enviroment and i remove the cooling fan about every 3 months on My main PC and it's shocking how much dust has built up in that time and it's only when you remove fan and have a good look between the cooling fins you can really see how much has built up.

. . . when you have excluded the impossible, whatever remains, however improbable, must be the truth.
