Hi,
If you've got a modern CPU, you need a CPU cooler. Gone are the days when PC CPUs could get away with just a little aluminium heat sink stuck on top of them, or no cooler at all. When any Intel or AMD CPU on the shelves today is going full blast, it's pumping out heat - less than 20 watts for current Celerons, less than 30 for current P-IIIs, something around the 40 watt mark for current Durons, and better than 70 watts for top-of-the-line Athlons.
Thanks,
Devid
