saint, that is for the dual core P4s coming out, but that was just a prototype, the coolers will not be that huge.

Yeah, as a matter of fact, I bought one a couple of weeks ago as described in the Peltier Beer (http://www.physicsforums.com/showthread.php?t=47149) thread. That looks to be THIS (http://www.crazypc.com/Merchant2/merchant.mv?Screen=PROD&Product_Code=50071) hsf but with a big fairing and 2 fans instead of one. Notice the copper heat pipe peaking out from under the fairing.

I don't have it mounted on my PC, and I'm not sure if will - but it does a heckuva job cooling that peltier.

I dont think your going to have good luck with that if it doesn't dissapate more heat than the backside of that pelt dissapates, you might want to check it out.

I've only done some pretty basic experimentation, but it does cool a heatsink on the cold side below freezing. I'll post some pics in that other thread this weekend.

what is the wattage on the pelt and the wattage dissapation per hour on that heatsink.fan combo?

what is the wattage on the pelt and the wattage dissapation per hour on that heatsink.fan combo?THIS (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4660&item=3847042208&rd=1) is the peltier I'm using. I don't have a performance curve for it and I didn't measure the amperage it was drawing, but it was taking 11v from a 12v power supply - the power supply couldn't keep up. I'm guessing that it was drawing 7-8A, so about 80-90W. I tested it with the cold side hsf fan both on and off. With it off (and therefore ony sucking a few watts in) it was below freezing, though I'm not sure how much because my thermocouple quit at freezing. All the fins frosted over though. So figure in that condition, the big hsf was dissipating 100W or so. And the hot side of the peltier only got up to about 125F, so dissipating 100W wasn't a problem for that hsf. I'll see if I can get some better numbers (maybe tomorrow)

that sounds like you are going to have a happy happy processor.
I may also look into one of thos pelts.
you will need an extra PSU or a bigger PSU to operate that pelt.
