Design and Functionality

At first glance you realize that with their CNPS7500 model Zalman stepped back into far away 2004, when we all were fascinated with the cooling efficiency of the CNPS7700-Cu. Just take a look:

Yes, it is indeed the same CNPS7700, but smaller in size (CNPS7500 measures 121 x 121 x 67mm while CNPS7700 -136 x 136 x 67mm) and weighing a little less (848g CNPS7500 vs. 918g CNPS7700). The cooler design remained absolutely the same and looks like a cup made of thin copper plates:

Inside there are blades of a 120mm fan, which rotation speed may be adjusted from 1150 to 2300RPM at 17-32dBA of noise. The fan blades sit on the fan core and are fastened with screws on two sides.

The crews and two aluminum plates hold the copper rib array firmly together at the base. The base surface is very even, but is hardly finished at all:

You can feel the machine traces, so you might want to polish it off in order to win a few additional degrees during CPU cooling.
