120mm | High Pressure Blades

The ETS-T40s is suitable to all kind of systems thanks to its space-saving design and offers a perfect balance between cooling performance and noise level. The slim heatsink doesn’t interfere with the RAM slots and allows the installation of high end modules.
Innovative technologies such as the Vortex Generator Flow (VGF) and the Vacuum Effect Flow (VEF) ensure optimum airflow and efficient cooling. The Heat Pipe Direct Touch technology ensures fast heat transfer to the 4x 6mm heat pipes. Cooled by a 12cm High Pressure Blade fan with a speed range of 500-1.500 RMP the ETS-T40s cooler supports up to 180W TDP cooling performance.

Air Flow Optimizations

Vortex Generator Flow (VGF)
In aviation, spoilers, the so-called vortex generators, are used to guide the airflow evenly along the wings. Enermax engineers have applied this technology to the CPU heat sink: Small spoilers on the fins next to the heatpies create a vortex which brings more fresh air to the back of the heatpipes.

Vacuum Effect Flow (VEF)
The partially closed sides of the heat sink create a vacuum that additionally draws fresh air from the side.

Heat Pipe Direct Touch (HDT)

With the patented Heat Pipe Direct Touch technology the heat pipes rest directly on the CPU. The advantage against a base plate is the faster transfer of heat without any additional resistance.

Full RAM Compatibility

Due to its slim construction, the heatsink does not block any memory slot at the mainboard.

High Pressure Blades

The ETS-T40s is equipped with a 12cm High Pressure Blade fan designed for use on CPU coolers. The patented Twister Bearing technology ensures smooth operation and a long service life of up to 160,000 hours MTBF.
The 9 High Pressure Blades rotate at 500 – 1,500 RPM to ensure silent operation.

Detachable Fan Blades

Thanks to the Twister Bearing technology ETS-T40s’s fan blades can be detached for easy cleaning. Release the fan blades by appling pressure in the center of the rotor from behind.


Quick & user-friendly universal mounting system supporting Intel® and AMD® sockets (excluding TR4/SP3 socket). The pressure adjustment spring system and high conductive Dow-Corning® thermal grease ensures a perfect contact with the CPUs heat spreader.
