Do I need a cpu cooler?

yes you need a cpu fan for any cpu

yes yes and more yes

make sure its certified for the company etc.. and for the clock speed

--call it what you wish, with this machine I can make mercury flow in 3 directions at once--

that all depends.. im assuming you are going for quietness.
if you have a modern process that runs at a low clock rate, you may be able to get away with one of those fancy "fin" heatsinks as shown on toms cooler roundup.
of course if your using a top of the line processor at high Mhz forget it.

but you could use a big heatsink with a small slow fan, or go for one of those nifty silveraado's. nice and quiet
thats assuming you want a quiet computer....

actually it doesn't really have to be certified. Any heatsink with good performance will do. In fact many cpu coolers are not certified by cpu manufacturers but are better than the certified ones

Press any key to continue...
I can't find the any key!!!

Tbirdside i have to disagree with you

Ive seen tons of processers with just a plan old cheep heat sink my P 1 has a tiny heat sink and even my friends P 3 has a heat sink only so i think your statment isnt that totly true <b>All CPUs need at least a Heat Sink</b>
