Overclockers.com received a Hydrocool 200 unit from Corsair, renowned company for their high-end memory products. If you want to learn more about the unit, read our article over here first. The review is very positive overall. Hydrocool 200 is an external unit. At its highest speed (Turbo), Die Simulator results place the HydroCool at the top of watercooling kits tested to date (Heatsink Ranking). At its low fan speed, results still place the HydroCool in the top rank. This is much better than I expected, considering the smallish waterblock.
