While I agree that cooling is important, it's wrong to say that 
overclocking is in any way detrimental in and of itself, or that it 
requires any special cooling equipment.  What cooling you need depends 
entirely on the chip and the box and the fan and any number of issues, 
and you can easily overheat a computer just by putting in too much 
memory or too fast of a disk drive.

That's why I mentioned that my E2180, running at 150% of rated speed, is 
doing fine at 85 degrees with stock cooling.  It really depends on a lot 
more than just the CPU speed.  And this is especially important: 
overclocking by frequency alone will SLIGHTLY increase heat, but not 
nearly so much as if you apply extra voltage.  I'm pretty comfortable 
saying that bumping up speed by frequency alone will not require much, 
if any, more cooling than running at rated speed.  It's the voltage 
increases that kill you (and shorten the life of your CPU considerably).
