The ENERMAX ETS-F40-FS Solid Black offers an outstanding cooling capacity of up to 200W TDP. Paired with a 140mm silent fan with a maximum noise level of 23dB(A), this makes the CPU air cooler the best choice for silent, media and gaming PCs. Particularly the optimized PWM control of the ETS-F40-FS Solid Black with low starting speed (300 – 1200 rpm) makes no compromise between noise and excellent performance. The four asymmetrical 6 mm heat pipes with Heat Pipe Direct Touch provide best RAM compatibility and fast heat transfer. The deep black coating of the heat sink and the top cover give the cooler its sleek appearance and make it a must-have for fans of black hardware.

ETS-F40-FS Silent Edition


The ETS-F40-FS Solid Black is a tower design cooler with copper heat pipes. Evaporation and condensation of a liquid inside the heat pipes are being used to transfer large amounts of heat to the heat sink. This technology is not only free of maintenance, long-lasting, and reliable, but also environmental friendly since it does not use poisonous chemicals. The black thermal conductive coating protecs against oxidation without compromising the heat transfer and a black top cover finally completes the dark look.

Vortex Generator Flow (VGF)

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

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.

Asymmetric Heat Pipe Design

The asymmetrical heat pipe design creates additional space for the fan to prevent high RAM modules from being blocked.

140 mm Silent Fan

The ETS-F40-FS Solid Black is equipped with a 140mm fan. The 9 sound optimised blades can rotate at very low speeds of only 300 RPM and are limited to a maximum of 1.200 RPM to support ultra-silent operation at all times. Due to the size of the fan, there is still a strong air flow for a cooling capacity of 200W TDP. A second set of mounting brackets allow the installation of an additional 120 or 140 mm fan for extra performance.


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 ensure perfect contact with the CPUs heat spreader.
