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. > For a fair comparison to the G3, you need to consider at least a Pentium > III (at about half again faster clock speed ;-). 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, ...
