SilentiumPC Fera 5 Dual Fan – Budget Cooler with Zero Fan Mode

SilentiumPC is a PC hardware manufacturer that was founded in Warsaw, Poland in 2007. The company’s main focus in the development of their products is on the most affordable, yet well-equipped components with a solid workmanship. The focus is mainly on cases and cooling products such as CPU coolers, fans and AiO water cooling systems.

In April, the manufacturer introduced a new CPU cooler called Fera 5. At first glance, the new CPU cooler hardly differs from its predecessor, the Fera 3. Main differences can be found mainly in the included fans. A zero-fan mode is supposed to allow semi-passive operation. In addition, there is a simple mounting system and a black cover for the ends of the heatpipes. The price of the Fera 5 with one fan is 26 Euros (current: Price not available *) and with two fans 33 Euros (current: Price not available *). Whether the SilentiumPC Fera 5 can assert itself in this hotly contested price range, you can find out in this review.

Packaging & Scope of delivery

Visually, SilentiumPC brings some color to the Fera 5. The cardboard packaging is printed in black, white and blue. Also on the box is a product picture of the cooler and all relevant technical data about the SilentiumPC Fera 5 Dual.

Opening the lid of the box, you are immediately greeted by the assembly accessories and colorful assembly instructions. The bag of accessories contains four fan clips, a tube of thermal paste and all mounting materials for all common sockets including backplate.  Separated from a thin layer of cardboard, the heatsink and the individually packaged fans can then be seen. The latter protect the heatsink from damage during transport. The underside of the Fera 5 is additionally protected by a mat made of foam.

Design & Workmanship

The cooling tower on the Fera 5 consists of a total of 56 aluminum fins. The tower is quite narrow and symmetrically placed above the base. A total of four copper heatpipes, each with a diameter of six millimeters, are supposed to absorb the CPU’s heat and transfer it to the fins. These technical features are then joined by a heatsink base with Heatpipe Direct Touch technology. The heatpipes lie directly next to each other. This makes the base look quite small compared to other heatsinks. The cover plate of the Fera 5 is made of black plastic and covers the ends of the heatpipes. This helps to achieve a uniform look.

The included Fluctus 120 PWM fans are a new development from the manufacturer. The fans have a frame width of 120 millimeters and feature nine specially designed fan blades. Together with the FDB bearing, this design is supposed to provide for a pleasant running smoothness. The fan blades as well as the frame are completely black in design. SilentiumPC has also equipped each fan with eight rubber decouplers. Power is supplied via a 4-pin PWM connector for each, which also has a Y-switch built in at the same time.

Fully assembled, the Fera 5 Dual weighs in at 935 grams. With only one fan, it has similar dimensions to other CPU coolers in this price range. The overall workmanship of the heatsink and fans is on a good level. There were no scratches or bent fins and the base of the socket was also properly machined. Only the plastic backplate leaves and a little doubt about the stability of the mounting system.


For the review, we are using a test system on a benchtable. This allows us to rule out factors such as heat buildup in the case. The test system consists of the following components.

For AMD systems, mounting the Fera 5 turns out to be quite simple. After the retaining brackets on the front were removed, could be prepared in the backplate of the AMD retention module. For this, a total of four spacers had to be screwed into the backplate on the front. The silver metal retention bracket is then placed on these spacers.

The retaining bracket is then secured with four screws to hold it firmly to the motherboard. After applying the thermal paste to the bottom of the CPU cooler, the Fera 5 could be placed on the CPU. Then, the screw connection between the retaining bracket on the cooler and the retaining frame on the motherboard is done via two spring-loaded screws.

The mounting system is thoughtfully designed and allows for a frustration-free installation of the CPU cooler. The Fera 5 is designed in such a way that even with the two fans, there should be no problems with VRM coolers or high RAM heatspreaders.

Loudness and cooling performance

As pointed out in the previous chapter, we are using an AM4 system based on the Ryzen 5 1400 and the MSI B350 PC Mate as our test hardware. The Ryzen runs at 3.8 GHz at 1.25V. To warm up the processor, it was loaded with Prime95 for 15 minutes. The CPU’s temperature was then read with the CPUID hardware monitor and the room temperature was around 20 °C during the measurements.

Cooler Operating scenario RPM Temperature
AMD Wraith Stealth 50% PWM 1600 rpm 102 °C (crash)
AMD Wraith Stealth 100% PWM 2650 rpm 86 °C
Enermax ETS-F40-FS 50% PWM 700 rpm 56 °C
Enermax ETS-F40-FS 100% PWM 1300 rpm 54 °C
SilentiumPC Fera 5 Single Fan 50% PWM 1000 rpm 58° C
SilentiumPC Fera 5 Single Fan 100% PWM 1800 rpm 54 °C
SilentiumPC Fera 5 Dual Fan 50% PWM 1000 rpm 55 °C
SilentiumPC Fera 5 Dual Fan 100% PWM 1800 rpm 53 °C

The SilentiumPC Fera 5 does very well despite its rather compact dimensions. Compared to our reference cooler, the Fera 5 can easily stand out with two fans. If one does without a fan, slightly worse but still good temperatures are achieved for an overclocked 65W CPU. With a range of 300 to 1800 rpm plus the zero fan mode, the fans can cover a very wide speed range. However, it should be noted that the noise increases significantly above 1000 rpm and can definitely be called annoying in the upper range.

The Zero Fan mode is basically practical, but not absolutely necessary in our eyes. Even between 300 and 400 rpm, the fans are so quiet that they shouldn’t be audible from the overall system.

Summary of the SilentiumPC Fera 5 Dual Fan

Overall, the SilentiumPC Fera 5 brings everything that is important for a budget tower cooler. It brings a solid performance to the floor, with which it does not have to hide from the competition and which should be sufficient for all mid-range CPUs up to 105W TDP. Moreover, the workmanship is on a good level and the basic look is appealing. Although the buyer has to do without a black anodization and RGB effects, the ends of the heatpipes are covered by a cover.

The mounting system of the Fera 5 is generally solid and holds our AMD test system bombproof. Intel systems, on the other hand, use an included plastic backplate. This seems quite thin to us, but should basically serve its purpose. Finally, there is the relatively small base of the heatpipes. The heatspreader of our Ryzen 5 1400 was not completely covered by the heatpipes. However, this does not seem to have had a real impact on the temperatures. Depending on the chip layout, worse temperatures could be expected, though.

At a price of 26 euros (current: Price not available *) with one fan or for 33 euros (current: Price not available *) with two fans, the SilentiumPC Fera 5 is still a good CPU cooler and therefore gets a buy recommendation from us.
