Zalman CNPS9500 AT Ultra Quiet High Performance Copper CPU Cooler

Zalman have announced the release of their new CNPS9500-AT Aero Flower Cooler. The CNPS9500-AT is virtually the same as the LED version. The main difference is that the AT version is only compatible with Pentium LAG775 systems. This is because the AT is supplied with a PWM fan. A PWM fan is designed to increase and decrease its RPM depending on the temperature of the CPU and BIOS settings.

Check out the performance chart Zalman compiled showing the excellent performance of the CNPS9500-AT.

Just like the LED version the AT version is an exceptional cooler. The primary innovation lies in the patented ‘figure of 8’ shape bending of the heatpipes. This produces the effect of up to six heatpipes when in actual fact there are only three. The excellent cooling performance and efficiency of the CNPS9500-AT is achieved by the aerodynamically designed ultra-slim heatsink fins and their performance optimized layout. This layout reduces airflow resistance and minimizes the weight of the cooler.
