High Performance CPU Cooler

8-Shaped Bending Design

Two independent heatpipes are bent and twisted in an “8” configuration that creates stable weight distribution and cools down motherboard and surrounding components.

Improved Air Flow by TAC Fin Utilization

TAC Fin(Turbulence Acceleration Convex Fin) centralizes the heat concentration for effective cooling

Effective Thermal Dissipation through X-Slit Fin

Strategically placed fins efficiently transfer the heat from the heatpipes

Slim Size Improves Compatibility and Convenience

Minimizes clearance issues with standard and high profile memory modules

Anti-corrosion and High Luster Finish Nickel Plating

The nickel plated body is resistant to corrosion even during prolonged use, and the black pearl finish along with the Blue LED emitted by the fan creates gorgeous aesthetics

120mm PWM Blue LED Fan

Users can visually confirm the status of the fan and provides more options in modding the case

High Performance ZM-STG2M

High Performance ZM-STG2 thermal grease fills the air pockets between the CPU and the base of the cooler with minimal application and significantly increases the cooling performance.

Thermal Grease



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.
Check the components list and condition of the product before installation. If any problem is found, contact the retailer to obtain a replacement.
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 specifications may be revised to improve quality and performance.
Enable PWM function in BIOS settings after installation.
Zalman Tech Co., Ltd. is not responsible for any damages due to external causes, including but not limited to, improper use, problems with electrical power, accident, neglect, alteration, repair, improper installation, or improper testing.
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)
