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.

※ Quiet Mode (w/ RC33P): 800 - 1300RPM / 18 - 28dBA ±10%
※ Normal Mode: 1000 - 2000RPM / 19 - 38dBA ±10%
Ultra Quiet 120mm Blue LED Fan
An ultra quiet 120mm fan is incorporated for minimized noise and Blue LEDs heighten the cool aesthetics.
Omega(Ω) Heatpipe Design
The CNPS9900A LED’s distinctive Omega(Ω) design not only provides excellent CPU Cooling but also effectively cools surrounding components for excellent system stability.
High Performance Super Thermal Grease ZM-STG2
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.
Versatile Compatibility
CNPS9900A LED accommodates a broad range of sockets.

Zalman affixes a Computer Noise Prevention System (CNPS) mark to all components used for noiseless computers.
Use and keep product away from reach of children and pets.
Do not ingest the Thermal Grease, and avoid its contact with skin and eyes. If contact is made with skin, wash off with water. If ingested or irritation persists, seek medical attention.
To prevent possible injuries, gloves must be worn while handling this product.
Excessive force exerted on the fan may cause damage to the fan and/or system.
Avoid inserting objects into the fan while it is in operation.
Check the components list and condition of the product before installation. If any problem is found, contact the retailer to obtain a replacement.
Zalman is not responsible for any damages caused by overclocking.
During transportation of the system, the cooler must be removed.
Zalman is not responsible for any damages that occur during the transport of a system.
Product design and specifi cations may be revised to improve quality and performance.
Liquid metal thermal grease unlike the normal thermal grease it contains electrical conductivity and causes aluminum cooler to rust therefore please avoid using it. Corrosion and short circuits caused by using aluminum cooler are users' responsibility, so please read this carefully before using. (EX: Liquid Pro, Liquid Ultra etcs)
