Zalman continues to refine the art of silent cooling.  The Reserator 2 is an outstanding fanless cooling solution capable of handling the latest CPUs and video cards.  The Reserator 2 exhibits excellent build quality and looks great.  It comes with both a CPU and VGA waterblock along with everything else needed for easy installation.  Yes, there are other water cooling systems on the market that deliver higher performance cooling but none that are passive, fanless, and silent like the Reserator 2.


While not really a complaint, I will offer a warning: care must be taken to purge all of the air out of the system and establish consistent flow.  This proved to be more difficult than with other water cooling systems I have used, but once accomplished the Reserator 2 performs extremely well.  (I have been using it reliably for over a month now without any issues.)  The User’s Guide is very well written — do yourself a favor and read it, then follow the directions. 


The Zalman Reserator 2 is available with an MSRP of $349.95 USD and is currently on sale at for only $309.95 or from for $319.99.
