Zalman CNPS12X / CNPS 12X Cooler Review @ Tweaknews
 

To sum up, the CNPS 12X is a very worthy addition to the Zalman stable. The six composite heatpipes and triple fan/dual radiator design yields excellent cooling performance at a very modest noise penalty. The cooler's enormity may limit its use in some cases and it's a bit fussy to install, but the 12X will deliver some astounding cooling performance in exchange for some diligence and patience on the part of the user.
