AN, X 2 to spend the extra dough :-)

But since you asked, yes there are some things to consider if your going to put a heat sink on something yourself and it's not all that simple. You have to account for how much heat you have to dissipate, the time you have available to dissipate it, the efficiency of the heat transfer in varying conditions, and the size/weight available to your sinking solution.

You could toss on any sink you wanted, and hope for the best. But a great company like Castle Creations has already done the math, R&D, beta testing, and they'll back it up with a warranty for a year ;-) All that crap you don't need to worry about for an extra 30 bones, you can't go wrong.
