Scythe Fuma 2 in test – Asymmetric all-rounder for hot hours

If you take a look at the German charts – the CPU coolers of course – then the coolers of the manufacturer Scythe with beQuiet are jostling for the top places. With 18 years of experience in the field of passive and silent cooling, the Tokyo-based company, including a branch in Germany, should be well prepared for this battle. What exactly makes the Fuma 2 so popular, besides its “fits everywhere” design and moderate price, you will find out in the following article:

Packaging / Scope of delivery

Away from a small pad of foam to pad the fins, the packaging and its interior is made entirely of cardboard. Plastic bags are also used sparingly, there is not much rubbish left after unpacking. The outside of the box is completely printed, besides product images and features, there are also various specifications and dimensions on the sides.

In addition to mounting brackets and fan clamps, we have a generous tube of thermal paste, 4-pin PWM fan splitter and small screwdrivers in the accessories. The Intel backplate is even already prepared, screws and plastic fixings were already attached in the factory.

Assembly / Installation

For the AM4 socket the existing backplate is used, with four rubberized spacers and screws the two silver brackets are mounted. After fixing the two spring-loaded screws in the brackets with the enclosed screwdriver, only the fixing of the fans is missing.

In contrast to many other coolers, the fans are only loosely attached to the cooler at the factory, so with the differently sized clamps, Kaze Flex Slim (front) and Kaze Flex 120 (middle) are still hooked in themselves.
Both fans are generously rubberized and run in opposite directions to each other, which should lead to a higher static pressure. In the picture of the side profile, the asymmetrical design of the Fuma 2 can be seen once again. Neither on the front nor on the back, RAM banks are blocked, the rather low installation height of almost 155mm should fit into most cases.

The cooler is overall well made, especially the winding heatpipes are impressive. Here and there a few cooling lamellas are not completely deburred. Bloody fingers should not be expected now, but there is still a rough feeling when painting over them.
