[luau] Underclocking

[MonMotha]

Be REALLY careful with peltiers, as the sudden change in temp can do 
really nasty things (like CRACK your cpu core, I reccomend a slab of 
copper stuck in the middle to provide a bit of a buffer while still 
having good heat transfer).  Also, peltiers suffer from condenstaion if 
you're not careful when you seal them (you do have to muck around with 
silicone sealant if you want to be safe, I assume it's pretty humid in 
Hawaii :).

Also remember, peltiers aren't magic.  They just allow you to move heat 
faster, and they actually generate a non-trivial amount of heat in the 
process, so you'll actually end up with MORE heat to exhaust.  This is 
why they're usually used in overclocking rigs where faster heat transfer 
is desired at the expense of greater heat generation.

If you still feel like checking out a peltier, www.3dcool.com has them, 
and bunches of other cooling products.
