I agree that it may work good for a graphics pelt, or something that could require little assistance. I understand that the heat given off by a cpu would greatly increase the heat variation, and therefore the expansion/contraction. Perhaps mercury could buy one of these stifty's and put a 226W pelt?
That may be less costly and provide the answer? I look forward to hearing the conclusions. I'm not rich enough to roll the dice on that guess though.
