The Enermax ETS-N31 is a tower cooler with 92mm fan designed to cool compact PC systems. The cooler has a low profile of only 125mm and comes with a tool-less top mounted installation system. The 3x Ø6mm heat pipes with Heat Pipe Direct Touch (HDT) and the air stream optimizations Vortex Generator Flow (VGF, patented) and Vacuum Effect Flow (VEF) work together to reach a cooling performance of 130W TDP. The asymmetric heat pipe design provides the best compatibility with high RAM modules. ETS-N31 supports all latest Intel® and AMD® sockets including LGA1700 and AM5.

Asymmetric Heat Pipe Array
The heat pipes are arranged in an asymmetric way so that the cooler does not interfere with RAM modules.

Vortex Generator Flow (VGF)
Small spoilers at the fins lead the air stream close along the heat pipes and cool them more efficiently.

Vacuum Effect Flow (VEF)
Air vents at the side of the heat sink use the difference in pressure to increase the fresh air supply.

Heat Pipe Direct Touch (HDT)
The heat pipes rest directly on the CPU to dissipate heat more effectively with lower thermal resistance.
