The Enermax ETS-N31 is a 92mm fan tower cooler designed to cool compact PC systems. The cooler has a low profile of just 125mm and comes with a tool-less top-mounted installation system. 3x Ø6mm heat pipes with Direct Pipe Heat Touch (HDT) and Air Flow Optimizations Vortex Generator Flow (VGF, Patented) and Vacuum Effect Flow (VEF) work together to achieve 130W TDP cooling performance. The asymmetric design of the heat pipe provides the best compatibility with high RAM modules. ETS-N31 supports all the latest Intel® and AMD® plugs, including AMD AM4.

Asymmetric heat pipe
The heat pipes are arranged asymmetrically, so that the refrigerator does not interfere with the RAM modules.
Vortex Generator Flow (VGF)
Small spoilers on the fins
 conduct close air flow along the heat pipes and cool them more efficiently.
Vacuum Effect Flow (VEF)
Ventilation openings on the side of the heat sink use the difference in pressure to increase the supply of fresh air.
Direct Contact Heat Pipe (HDT)

Heat pipes are supported directly on the CPU to dissipate heat more efficiently with less thermal resistance.
