Front and rear airflow incident angles are designed in different directions. 
This cross bending fin technology 
produces cooling performance with minimum noise.

3 composite heat pipes and pure copper cross 
bending fins quickly cools down the heat from the CPU.

Zalman's 'Compositd Heatpipe' features a 'Sintered Metal'
type wick, resulting in outstanding capillary pumping performance. 
and a high thermal conductive design of 'Axial Greeves' which increases 
the heat transfer rate by 50% compared to ordinary heatpipes.

Cross Bending ultra quiet powerful 120mm Front Fan and 140mm Center Fan produces top performance.

Beautiful blue LED dual fan

Zalman`s unique sanding process provides excellent heat transfer ability.
With height 160mm and width 180mm it fits in a variety of cases including mid case.
Compatible with Intel Socket LGA 2011/1155/1156/1150/1366, AMD Socket FM2, FM1 and most Intel, AMD platform.
High performance ZM-STG2 helps to maximize the heat transfer from CPU to CNPS9900DF base allowing 
optimal cooling performance.
