X-bit Labs has taken a look at the Zalman Reserator XT liquid cooling system:
Showcased in early spring at CeBIT 2007, the Zalman Reserator XT active liquid cooling system has finally reached our labs. We are glad we can offer you our review of it and we want to note right away that Zalman has for the first time stepped away from its fan-less cooling concept embodied in the Reserator 1 (see our article called Aesthetic Water Cooling Solutions: Zalman Reserator 1, ZM-WB2 Gold and ZM-GWB1), Zalman Reserator 1 Plus (see our Zalman Reserator 1 Plus Liquid Cooling System Review) and Zalman Reserator 2 (see our article called Perfect Silence: Zalman Reserator 2 Fanless Liquid-Cooling System Review).
The new system employs a 140mm fan with a controllable rotation speed. This is not the only difference of the new Reserator from its predecessors, though. It features several innovations that are going to win wide recognition among overclockers of this world.
Check it out over here. The reviewer says the Reserator XT performs very well, it outperforms a very high-end air cooling solution like the ThermalRight Ultra-120 eXtreme (with two fans) by 10°C. Unfortunately the product has a very high price tag, it retails for about $399.
