hi-techreviews.com posted a Zalman Reserator 2 review
Zalman has made a name for themselves by catering to the PC user that demands a quiet PC, I'm not talking about the person that can tolerate a pair of 12 volts fans running at 7 volts either. It's long been known that one way to reduce noise is to convert to a water cooling system, yet the drawback there is you have to fight the noise of the fan and the exposed water pump. So you may gain a little but you will not achieve pure silence.Zalman Reserator 2 Review
The Reserator 2 water cooling system that we are reviewing today may be the closest you can get to absolute silence in a PC setup. Since the unit has no fans and has a submersible pump built into the unit, what sound it does make is barely audible. So come on along as we check out this awesome piece of gear from Zalman and see if you like it as much as we did.
