Third time’s the charm? Scythe has the Fuma 3 CPU cooler

One of the youngest “brands” or series of Scythe coolers – Fuma – is growing with a new model. The Fuma 3 builds on its predecessors with a dual-tower heatsink design, and hopefully with even higher cooling efficiency. Dimensions haven’t changed much between generations, but some fins have grown and weight has increased. Regarding this cooler, Scythe is talking about a new flagship with aerodynamic optimizations.

The Scythe Fuma cooler features two separate bundles of fins (like the Scythe Mine/2 used to be) that sandwich a fan. And then to increase the airflow through the heatsink, there’s a single fan on the front tower as well – basically a fairly traditional design you’re familiar with in these types of coolers.

The new Fuma 3 doesn’t look much different from the Fuma 2 (rev. B) in rough outline. At virtually the same height (154 mm), the Fuma 3 loses a millimetre in length with 128 mm, according to the technical drawing, but has it extra in width. This may possibly be due to the more protruding fan clips, but in any case it is an unimportant detail.

In terms of weight (1095 g), the parameters already point to a more remarkable difference. The Fuma 3 has gained around 10%. Part of that is the plastic top cover, but part of it is certainly the different, fuller fin profile. While the Fuma 2’s heatsink has alternating shorter and longer fins, the Fuma 3’s are just long.

Sure, the Fuma 3 also combines several types of fins, but within a single tower they all seem to be the same. They’re shorter on the front tower, longer on the rear, and a few are shortened on the bottom to improve compatibility, either with memory on platforms with DIMM slots on both sides of the CPU socket, or because of VRM coolers on other boards. In fact, the Fuma 3’s heatsink is significantly offset so that the front fan doesn’t collide with the memory. Admittedly, Scythe had to help this along by narrowing the fan profile to 15mm (similar to the Cryorig R1 Universal cooler, for example).

Two 120 mm fans are used. One is slimmer – Kaze Flex II PWM Slim and the other with standard thickness of 25 mm or 26 mm with anti-vibration pads – Kaze Flex II PWM. The speed range of both is the same, 300–1500 rpm, with the thicker fan having up to twice the airflow at equal, lower speeds, and as much as 71% more at the maximum speed (with 114,88 m³/h). The static pressure of the thicker fan should also be significantly higher (up to 1,50 mm H₂O compared to 0,96 mm H₂O).

Six 6 mm thick heatpipes are used to transfer the waste heat to the heatsink through the nickel-plated copper coldplate. The cooler is compatible with all newer AMD (AM5 and AM4) and Intel (LGA 1700, 1200, 115x, 2066) sockets.

The Fuma 3 is already on sale in Southeast Asia, with availability reported on amazon.com starting July 20. We will try to get information on distribution in Europe and will add it to the article.
