The problem with laptops is that due to the limited space inside the 
unit the heatsink and fan isn't very big.  For instance I have an Acer 
Aspire 2920 (12.1" notebook with Core 2 Duo 2GHz), when it's running at 
full speed it does get hot and the fans kick in but the actual heatsink 
and fan assembly is quite small, less metal than what you'd get with a 
stock fan on a desktop.

I'm assuming here that Javadayaz has a desktop, and a desktop running at 
high temperatures like that isn't going to do it much good.  If he's got 
an Intel CPU then the CPU will throttle down to a slower speed to cool 
down a bit but AFAIK if it's an AMD CPU it won't throttle down, at least 
not by much unless Cool 'n' Quiet is enabled.
