All in all, not something that's meant to be implemented for general computer cooling.
Sorry about reviving the zombie but...
This is the second post I've seen dismissing cryocooler because of this low wattage.
There is a wattage curve based on temperature. These items are generally used at very low temperatures. That's why they advertise the wattage at 77K. But it will do 70 watts at 150K, and 150K is still -123 C. So, at a more reasonable temperature for this application, it will probably take out more than enough wattage.
I just wish I could find one with prices on it that was reasonably cheap. I'm thinking it would make a very efficient and quiet water chiller, too.
I contacted one of the sellers of cryocoolers (sunpower). Their units start at $10k and they're optimized for 50-120 K, so... not useful for what we're doing.Edited by taotree - 8/27/12 at 10:40am
