Powerful Cooling Performance
Two heatpipes and aluminum fins are designed for maximum cooling while switching noise free, down-blowing 110mm fan
minimizes noise and cools not only the CPU but also provides powerful peripheral cooling.
Direct Touch Heatpipe (DTH) Base
DTH technology transfers the CPU’s heat directly to heatpipes, thereby minimizing heat resistance and maximizing cooling performance.
Slim Profile
The CPU cooler’s height is 60mm and designed to be installed in ATX cases as well as slim or LP (low profile) cases.
Ultra Quiet 110mm PWM Fan
Switching noise eliminated 110mm fan is incorporated for ultra quiet operation.

※ ’Switching noise’ is the high frequency harmonic noise that can result from voltage regulation.
Versatile Compatibility
CNPS8900 Quiet accommodates a broad range of sockets.
- Intel LGA1155/1156/1150/1366/775
- AMD FM2/FM1/AM3+/AM3/AM2+/AM2
High Performance Thermal Grease
High performance super thermal grease ZM-STG2M maximizes heat transfer from the CPU to the base of CNPS8900 Quiet for intensified cooling performance.

Zalman affixes a Computer Noise Prevention System (CNPS) mark to all components used for noiseless computers.
Avoid inserting objects or hands into the fan while it is in operation to prevent product damage and injuries.
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.
Use and keep product away from reach of children and pets.
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)
