SPC’s new cooler – Fera 5. Many changes, price as for the old model

A new cooler from the SilentiumPC's popular family, Fera 5, has been released

The Fera series has the best long-term sales among cheap coolers. And it should be noted that quite deservedly so. However, the Polish manufacturer found weak spots in both the heatsink and the fan and significantly modified the design. That is both great and frightening. But this mostly seems correct and a detailed analysis with the internal tests of the new fan also makes a good impression. The shape of the blades and the bearings were changed.

SilentiumPC Fera coolers have been at the top of the low-end for a really long time and, ironically, even the five-year-old design of Fera 3 is enough for that. Although, some tests start to favor other coolers, too (see the tests of Arctic Freezer 34 and FSP Windale 4).

SilentiumPC can get an advantage again with Fera 5. It is strange that the cooler skips logical numbering scheme (Fera 4 never came out, the last one is Fera 3 ARGB), but of course the build quality and physical structure of the passive and active part of the cooler is important.

The stated dimensions of Fera 5 are similar to Fera 3. It is the same 155 mm in height, the width (77 mm) should be one millimeter smaller with the new cooler, but the area is extended (+ 3 mm) in the last axis, in the direction of the fin length. Whether it is due to the long fins or a more significant protrusion of the fan clips, we will find out in the tests.

SilentiumPC states they reduced the total weight (562 g), compared to Fera 3 by 48 g. Some part of it got lost in the jagged fins – they were straight in the predecessors, which is part of the acoustic optimizations that SilentiumPC focused on during the development.

In order to achieve the highest possible efficiency in terms of the best possible ratio of noise level to important static pressure, the fan itself should also be adjusted. The leading edges of the new Fluktus 120 PWM fan are also jagged. In addition, compared to the Sigma Pro 120 PWM (from Fera 3), the total area of the blades is larger (but also because Fluktus has 9 blades instead of 7) and the rpm is also increased from 1600 to 1800. Last but not least, SPC promises more robust bearings (FDB).

The comparison of fans (Fluktus 120 PWM with Sigma Pro PWM) at the level of frequency response and intensity of individual frequencies is remarkable. According to SilentiumPC measurements, Fluktus 120 PWM is quieter when achieving the same static pressure, especially at lower frequencies.

The base of the cooler is also new. Although the heatpipes are still in direct contact with the processor’s heat spreader, SPC has removed the gaps between them. These were previously filled with aluminum from a small heatsink, which does not contribute much to the cooling and more or less just holds the pipes together.

There was higher warmth in these places, which is no longer true for the new heatsink. All pipes are close together according to the pattern that Cooler Master once used with the Hyper 212 Evo, but later ironically abandoned it (for example, the Hyper 212 Evo v2 again has “aluminum” gaps between the tubes).

The passage of the heatpipe through the fins has not changed. But notice that the entire surface of the fins has holes, in order to achieve a larger area. Another detail is the more closed design of the heatsink along the short sides, which can also be beneficial in terms of cooling efficiency.

The Fera 5 cooler will be shipped with one or two fans. If you buy the single-fan version, you can add another fan later – there will be two pairs of clips in the accessories.

Finally, the small accessories for mounting to the socket are changed, too. On the one hand, it promises better contact (higher pressure) on the processor, on the other hand, it has fewer components (for example, instead of a pair of typical base brackets, there is only one solid frame in it) and thus the installation should be more comfortable. All current platforms (AMD AM4, Intel LGA 115x and 1200) are supported, as well as some obsolete ones (AMD AM3(+), AM2(+), FM2(+) or Intel LGA 775 and 1366), which can still be used.

The Fera 5 and Fera 5 Dual Fan coolers are available from today (April 8, 2021) for the recommended prices of 25.90 euros and 32.90 euros, respectively. The SilentiumPC’s warranty is six years.

SilentiumPC Fera 5 ARGB – Quiet, efficient and colourful

After a long hiatus, which was caused by a crash of the test setup, I am back again with CPU cooler reviews. Today I will focus on the ARGB version of the Fera 5 cooler from SPC. The Fera 5 cooler performed well beyond expectations in the tests and offered an interesting price to performance ratio. However, the ARGB version is equipped with a slightly different fan, so the cooler needs to be tortured again on a hot CPU and have its noise level measured.

News from Noctua: A cooling enhancing tunel and NH-L9i-17xx

Wind tunnels in the case above the cooler have formerly been rather common, but have gradually disappeared over time, however this does not mean that they are useless. Noctua now introduces such a tunnel. It is installed on the cooler and should increase its effectivity. This can be of benefit to small coolers on big CPUs. Simultaneously with this tunnel the 37mm high top-flow NH-L9i-17xx, which aims to take on the Alder Lake processors. Read more “News from Noctua: A cooling enhancing tunel and NH-L9i-17xx” »

AMD AM5 socket to be backwards compatible with AM4 coolers

It has been five years since the “Ryzen” brand was created. On this auspicious occasion, the gentlemen from AMD sat down at a table in front of the camera and it wasn’t all about retrospect. On the contrary, it also came out of the conversation that users will be able to install AM4 compatible coolers on future processors in the AM5 socket. No modifications to the mounting system will be required. It already contains everything needed. Read more “AMD AM5 socket to be backwards compatible with AM4 coolers” »
