Zalman CNPS9300 AT CPU Cooler Review
Components and Design
The CNPS9300 AT CPU cooler features a copper base (with aluminum cap), two figure 8 shaped copper heat pipes and a large, circular array of thin copper fins. Although there are physically just two heat pipes, the near figure 8 configuration results in four evaporator sections (where the ends of each heat pipe contact the base and absorb heat from the CPU) and two condenser sections (where heat is dissipated into the central copper fins). This affectively doubles the area where heat can be absorbed.
The CNPS9300 AT CPU cooler uses a built in Zalman labeled 92mm fan (ZD9225AUB) in the center of the copper fin array. This particular fan incorporates Superflo bearings and Pulse Width Modulated (PWM) speed control that permits the fan to operate between 1,500 and 2,400 rpm. The fan is designed to produce horizontal airflow thru the cooler, which may be coupled with a rear case fan for enhanced cooling.
The machined copper base of the CNPS9300 AT cooler exhibits a smooth machined finish and appears to be flat.
The CNPS9300 AT uses universal mounting hardware that supports both Intel LGA775 and AMD processor platforms. The Intel 775 mount features a bolt-thru design while the AMD mount clips onto a stock AMD retention frame.
