Kaze Flex II fan is now also on the Scythe Mugen 5 rev. C

One fan after another is changed on the Mugen 5’s heatsink. It wasn’t that long ago that we wrote a report on the “S” variant (with the Wonder Snail 120 fan), which supports the Intel LGA 1700 platform. And there really are a lot of variants that differ mainly by the fan. But this latest one, also referred to as revision C, might be the most efficient. At least among those options that are designated for Europe.

Scythe, in addition to adding native LGA 1700 support on several coolers, replaces the Kaze Flex 120 (Slim) PWM fan with the Kaze Flex II 120 (Slim) PWM, For example, in the case of the Fuma II rev. B or the Big Shuriken 3 rev. B.

For the Kaze Flex II, the shape of the rotor hasn’t changed, but there has been an acceleration from 1200 to 1500 rpm. So the cooler will be noisier, but better prepared for the more powerful models of current Intel Alder Lake processors. Back at the end of the year, Scythe seemed to have a more suitable, better optimized fan for the Mugen 5 than the Kaze Flex II. But the Model S was apparently released only for the Asian and American markets, it is not sold here. Scythe doesn’t even have a product page for it on the European website. It doesn’t even have one for the C revision yet, but that’s due to the fact that it’s a new product. According to Scythe’s official statement, this cooler will be available worldwide and will start shipping to Europe in April. In the US, Japan and Taiwan, the Mugen 5 rev. C is available now.

Compared to revision B, there are two changes. Firstly, the H.P.M.S IV (Hyper Precision Mounting System IV) mounting accessory for Intel LGA 1700 is already included with the cooler, and secondly, there is the new Kaze Flex II 120 PWM fan. There have been no changes within the heatsink design, at least not to the external ones.

The cooler is 154.5 mm in height, with which it ranks among the lower tower models in this higher weight category (900 g). The base of the heatsink is rotated towards the DIMM slots and thus the heatsink is angled away from the memory so that the fan can avoid even taller modules. In addition to LGA 1700, older Intel platforms are supported – LGA 115x/1200, 2066, 2011(-v3) and naturally AMD – AM4, AM3(+), AM2(+) and FMx.

The fan used has already been mentioned, it is a 120 mm Kaze Flex II PWM fan with a range of 300–1500 rpm. Scythe lists the airflow nicely for the entire spectrum, 28.71–114.89 m3/h. And the full range is also in the parameters for the static pressure values, these are in the range of 0.075 – 1.5 mm H2O. The Kaze Flex II bearings are Fluid Dynamic Bearings (FDB) and to reduce the intensity of vibration transfer to the heatsink body, there are anti-vibration pads in the corners of the frame.

Price of the Mugen 5 rev. C is still unknown, but it will probably be between 50–60 EUR, which is also the price of the Mugen 5 rev. B. How much it will really cost will be revealed next month by the price lists of vendors.

How a CPU Cooler Works. Intended for Secondary Schools

The purpose of a CPU cooler is to transfer enough heat away from the processor so that it can operate within its optimal parameters, for example clock speeds. These are only achieved within the expected range if the processor, in combination with the cooler being used, does not heat up more than is desirable for achieving attractive performance. Yes, everything usually revolves around speed, but that is also associated with factors such as power consumption. Read more “How a CPU Cooler Works. Intended for Secondary Schools” »

Computex 2026: New Hardware Outside the Main Spotlight

Computex is not just for the industry giants. Alongside major manufacturers, smaller brands regularly showcase unconventional designs and innovative engineering to capture attention. Some of these concepts prove to be developmental dead ends, while others pioneer features that later integrate into mainstream products. Even if not every innovation succeeds, many certainly deserve recognition. Read more “Computex 2026: New Hardware Outside the Main Spotlight” »

DeepCool AK700 Digital NYX: Single Thicker Tower (with a Display)

A relatively thick tower and as many as seven heatpipes. The fin surface area of the DeepCool AK700 Digital NYX is quite large, even though it is cooled by a single fan. This may be attractive for those who prefer tower coolers (typically over liquid coolers) but still want the best possible memory compatibility, which many dual‑tower designs obstruct.
