PC Apex Review has posted a review on the Ultra Products ChillTec Thermoelectric CPU Cooler

Heatpipe cooling has been around long enough now where I don't need to explain how that works, and I gave a very basic explanation of how TEC's work earlier. So why are there two heatpipes cooling what should be the cold side of the TEC? You would think that in order for the TEC to be more efficient they would have placed all four heatpipes on the hot side. Here is why they chose this design - 50W. A 50W TEC is no match for a modern CPU and would easily be overpowered by the heat generated. In order to overcome the limitation of the TEC, they augment the cooling by moving two heatpipes down to the bottom. I'm sure this was done to minimize the system power requirements (which is listed as a 350W PSU minimum) but I doubt the TEC will help a whole hell of a lot when a system is under load. It will be all heatpipe, baby. I would like to see this setup with a 150W TEC or better and see how it performs, but then the PSU requirements would go way up which would minimize the number of consumers available who could purchase the ChillTec.
