Well, ...

not so long ago i fried a Pentium 200 because i forgot to connect the fan ...

and believe me, it was not cold when i touched it, ...

Also it depends if your are using a tower or desktop casing, instead of a
laptop. The laptop is tiny, has no big cooling box and i think most heat of
your laptop comes from your harddisk, graphic chip, memory and DVD drive.

well, i think the pIII are less watt hungry, since they are done in a smaller
process. IBM is advertissing their G3 as using less than 6Watss, while PII
used more than 20/30 watts, not to compare with the fast athlons which use 50
watts and up. and since used watts are dissipated more or less into heat, ...
