Another cooler that we will have time to look at this year is the Scythe Fuma 3. This cooler uses several atypical design elements, which makes it different from the usual dual-tower coolers in its class. Moreover, with a price tag of just over 50 EUR, it could offer an interesting price/performance ratio. Additionally, this is my first experience with a Scythe cooler, so I’m also duly curious to see how the Fuma 3 performs in stress tests.
Key features of the cooler
Scythe Fuma 3 is a really interesting cooler. It is a highly asymmetrical dual-tower cooler that uses two completely different types of fans. While the rear tower hosts a classic 25mm fan from the Kaze Flex II series, the front tower, which is also relatively thin, hosts a 15mm slim fan. To make things even more interesting, the two fans rotate in opposite directions to each other, which can have an impact on both the acoustics and of course the overall efficiency.
So the front tower is really thin and it is also noticeably offset towards the centre of the cooler in order to, in combination with the slim fan, ensure maximum compatibility with RAM modules on the motherboard. The rear tower, on the other hand, is quite large and has a cutout at the bottom to avoid physical conflict with a passive power cascade cooler on the motherboard. In addition, another (third overall) fan can be mounted on the rear tower, whose usefulness will be verified in a future article.
The two towers are connected by six 6 mm diameter copper heatpipes with a nickel-plated surface. The large copper base through which these heatpipes pass is also treated with a layer of nickel and polished to a mirror shine. The upper surfaces of both heatsink towers feature a decorative cover with a very minimalist manufacturer’s logo. On the front tower, you can notice a pair of small cut-outs from above, which serve as a path for a screwdriver when installing the cooler.
The manufacturer is very generous with the accessories supplied with the Scythe Fuma 3 cooler and there is nothing important missing. The mounting system of the cooler is sufficiently robust and of appropriate quality. A very nice bonus is the handy long shank screwdriver for the easiest possible installation of the cooler. You will also find a tube of thermal paste in the package, including a small plastic applicator. There is also a splitter for connecting both supplied fans to a single PWM header on the motherboard. You will also find an additional set of clips for attaching a third fan to the back of the cooler. The accessories are then rounded off with a clear and well-designed manual.
The installation of the cooler is simple and straightforward, so you shouldn’t encounter any setbacks. Just make sure to choose the correct spacers according to the socket (LGA 1700 socket has its own set) and adjust the spacing of the screws on the supplied backplate in case of mounting on an Intel processor. During installation, you also have to remove the middle 120mm fan for a while and at this point you will fully appreciate the supplied screwdriver.
Cooler and fan parameters
Scythe Fuma 3 does not stand out from its class of coolers in terms of dimensions. A positive element is its overall height, which is just under 155 mm, which is sometimes the limit of compatibility of some smaller cases (for example, the popular Masterbox NR200P from CoolerMaster), without somehow reducing the overall density of the cooler or interfering with the compatibility with the RAM slots on the motherboard.
As mentioned, the Scythe Fuma 3 uses not only the asymmetrical heatsink design, but also an atypical fan configuration. On the front tower you will find the Scythe Kaze Flex II 120 PWM Slim, which is a 15mm thick fan, and on the rear tower you will find the classic Kaze Flex II 120 PWM. The static pressure and airflow values for these fans are not very high though, so hopefully the manufacturer knew what they were doing and these fans will be efficient enough in combination with the heatsink of the cooler over the entire speed range.
