Design and Functionality

The design of the new Zalman CNPS9300 AT is not that new at all. In fact, they borrowed the heatsink design from the pretty old Zalman CNPS9500 and CNPS9700 cooler models. The array of wavy plates sits on heatpipes and is cooled with a fan:

Zalman CNPS9300 AT is smaller than its elder brothers. It measures 61.35 x 108 x 132.5mm. It also has fewer heatpipes (two instead of three) and weighs less: only 407g. Other than that, it is exactly the same as CNPS9500/9700.

Zalman CNPS9300 AT uses only two copper heatpipes 6mm in diameter. They originate from the copper base, loop forming an unfinished 8 and return back into the base. This is what this heatpipe web looks like:

The heatsink copper plates are soldered to the heatpipes piercing them:
