Zalman CNPS9900LED 92 mm CPU Cooler Powerful Cooling Performance: Optimally designed pure copper fins effectively disperse heat away from the CPU via heatpipes, while the high capacity 120mm fan quickly cools the heatsink for stable operation of high performance CPUs.

PWM Fan Speed Control: The PWM(Pulse Width Modulation) Fan automatically adjusts fan speed(RPM) according to the CPU;s temperature,while the included Resistor Cable(RC33P) provides the option of reducing the input voltage for overall reduction of fan speed and noise.

Ultra Quiet 120mm Blue LED Fan: An ultra quiet 120mm fan is incorporated for minimized noise and Blue LEDs heighten the cool aesthetics.

Omega Heatpipe Design: The CNPS9900A LED¢��¯s distinctive Omega design not only provides excellent CPU Cooling but also effectively cools surrounding components for excellent system stability.

The included all new high performance thermal grease ZM-STG2 maximizes heat transfer from the CPU to the base of CNPS9900A LED for intensified cooling performance.

Compatibility: Intel LGA1156/1366/775, AMD AM3/AM2+/AM2/754/939/940. *Note: To use the CNPS9900 series coolers on socket 1156, ZM-CS5A must be purchased separately.

• Does not generate noise or vibration in Silent Mode. 100% copper heatsink with aerodynamically optimized tunnel design for maximum cooling efficiency. Patented heatpipe design for cooling performance of up to 6 heatpipes with the use of just 3. Ultra-thin 0.2mm fins for minimized weight and significantly reduced airflow resistance. Compatible with all Intel Socket 1366/775 and all AMD Socket AM3, AM2+/AM2/754/939/940 based Single, Dual, and Quad Core CPUs. Ultra quiet 120mm PWM LED fan for automatic fan speed control according to the CPU's temperature.
