The three 120mm fans spins at 1200-950RPM and draw power from a single 3-pin motherboard fan header. Each of the six composite wick copper heatpipes are 6mm in diameter and extend from the base up to the top of the 157mm tall heatsink. Each nickel plated aluminum fin measures 0.4mm thick and is spaced ~1.7mm apart. The first and middle fans look the same, the third features winglets.

Zalman's CNPS12X heatsink stands 157mm tall, the fin area is 151mm wide and the first fin elevated 33mm above the CPU socket. Heat pipes are positioned 6mm on center at the base plate and rise up through the fins with a pitch of 20mm or 17mm. The base incorporates a 13mm thick nickel plated aluminum block to distribute clamping forces.

The usable area of Zalman's CNPS12X exposed heatpipe base is 45x45mm. Looking from the top down we can see all three 120mm fans and the plastic strut which hold the two fin towers firmly in place. The translucent fans are softly illuminated with blue LEDs.
