Corsair was demonstrating the TEC unit at CeBIT 2009. TECs (Peltiers) work on the principle of running voltage through two dissimilar materials (semiconductors).  Joined together electrically, the voltage causes heat to be pulled from one side to the other, making it colder. The cold side helps drag heat away from the components you're cooling, but the hot side of the TEC requires cooling itself, and that's why you see the watercooling on top.

Put simply, TEC-assisted watercooling is better than basic liquid cooling because it drags the heat away quicker.

We managed to push our 2GHz CL7 kit to 2.1GHz CR1 with the DOMINATOR AIRFLOW, so it will be interesting to see just how much help the TEC provides. We have one in the labs right now, and we'll attach it to the modules this week.

What you don't see is the humidity sensor that ensures condensation doesn't take place on the cold side - the last thing you'll want is water dripping on to the components, right.

No word on the pricing and availability of the waterblock or TEC unit, but we'll update this article once we have news from Corsair.
