140mm Fan Ultra Quiet CPU Cooler
IHD(Interactive Heatpipe transfer Design)
Technology applied to keep your computer running smooth and stable.
Up to 2 additional 140mm fans can be installed
for overclockers and power users.
U-shape dual heat sink is designed to maximize the dissipation
area. Plus the aerodynamically constructed double-induction
heat sink increases the airflow maximizing cooling performance.
6 Heatpipes with double efficiency
Identical 140mm ultra quiet middle fan installed for optimal cooling performance.
Zalman’s unique sanding process provides excellent heat transfer ability.

With height less than 160mm it fits in a variety of cases including mid case(width 180mm).
Compatible with Intel Socket 1150,
AMD Socket FM1, FM2 and most Intel, AMD platform.
High performance ZM-STG2M helps to maximize the heat transfer from CPU to base allowing optimal cooling performance.
