Since we’ve reviewed the Silent Edition cooler from the ETS-F40 series, then it’s time on the Solid Black version. The Solid Black cooler is slightly different, but mostly because of the external design. The cooler is black, so it should match gaming components better.

To find out what else has to offer the ETS-F40-FS Solid Black cooler, you have to read our review. It’s for sure an interesting product and should match the needs of many users.

After the introduction and product features, we will present some test results based on the Ryzen 9 5900X platform.

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.


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 environmentally friendly since it does not use poisonous chemicals. The black thermal conductive coating protects 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 that 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-optimized 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 airflow 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 CPU heat spreader.

The specifications are the same as for the ETS-F40-FS Silent Edition cooler, of course, except that the Solid Black edition is painted black. The cooler is designed to work with processors up to 200W+, so it should handle nearly every modern processor.


Package and its contents

The package of the ETS-F40-FS Solid Black is about the same as in the previously reviewed version of the ETS-F40-FS. The box is well described and includes everything we may need for the installation.

Enermax ETS-F40-FS is equipped with a quiet and high-performance 140mm fan. It spins between 300 and 1200 RPM, but you can expect closer to 900 RPM for the most time.

The heatsink is equipped with four heat pipes which are designed to directly touch the CPU’s IHS (integrated heat spreader). This design usually gives slightly better results than the one covered with a cold plate. As you can see in the photo above, The surface is flat and nicely covers new processors.

The cooler itself doesn’t have any RGB lighting but is painted black. It perfectly fits popular recently whole-black or mixed black and white PC. Not all users like RGB illumination, while most users like black PC products. Below you can check how the cooler looks with the MSI X570 Unify motherboard, which is also made with a black-on-black design in mind.



The installation is quite simple and shouldn’t cause issues to less advanced users. Everything is well described in the attached manual. The cooler could be installed on ATX and ITX size motherboards. Tests were performed on the MSI X570 Unify motherboard, as you can see in the photos below.

The installation itself takes about five minutes on both AMD and Intel motherboards.

On the next page of this review, we will take a closer look at the performance.

All tests were performed on the AMD Ryzen 9 5900X, one of the more demanding processors on the market. Additional components contain MSI X570 Unify motherboard, HyperX Predator 16GB DDR4-4600 memory kit (even though on the photos is G.Skill), and ASRock RX 6800 XT 16GB graphics card.

There are three tests. The first is simply called Idle, so an operating system without additional load besides standard processes in the background. The second test is based on the PCMark 10 Extended benchmark, which simulates daily work and simple games. The last one is a high CPU load tested with AIDA64 and AVX instructions.

Like in previous cooler reviews with the Ryzen 9 5900X CPU, I have to add that the presented results are not fully clear. The full story includes the CPU frequency, which depends on the cooling potential of the used cooler. In this case, Enermax ETS-F40 series coolers were keeping about 100-200MHz (depends on used core) higher frequency during work than Noctua NH-U9S. Their performance was about as high as that of Noctua NH-U12S redux/ At the same time, we could see a bit higher frequency on Noctua NH-D15 or AIO coolers with 360mm radiators like Enermax LIQMAX III.

The ETS-F40-FS is performing well and is quiet, even at full fan speed. The same as in the Silent Edition cooler, also Solid Black was generating noise that was hard to register with the typical ambient noise around. We could register about 2-3dB higher noise during high load tests, which still keeps the ETS-F40-FS in the group of the quiet coolers and is hard to beat by most coolers on the market.

Results are about as high as that of the previously reviewed ETS-F40-FS cooler but also slightly better than Noctua NH-U12S The CPU could keep about the same frequency in all tests, and its temperature was about the same. The Noctua cooler was slightly louder under a high CPU load due to the higher fan speed.

Even though there is little difference between the ETS-F40-FS Silent Edition and Solid Black, the whole black cooler is somehow more convincing. Both coolers are great, but the black version would be my pick.

Conclusion and Verdict

The second ETS-F40-FS cooler is an improved version of the Silent Edition cooler. It’s still quiet and well-performing cooler, but it is the whole black. This is good news for all who like black-themed PC or simply dislike RGB illumination.

The ETS-F40-FS offers high performance, which is better than that of most competitive coolers. At the same time, the ETS-F40-FS is inexpensive. The Amazon DE store sells the ETS-F40-FS Solid Black for around €45. The Silent Edition is cheaper, but there is no promo price on the Solid Black right now. I guess you can find it even cheaper. Even if not, then it’s a good deal for everything this cooler has to offer.

The next Enermax review will cover the ETS-F40-FS ARGB cooler, so something for RGB illumination fans.
