Scythe has made the installation as easy as possible for us here. Preparatory you screw the mounting rails to the backplate. Already before you insert the cooler, you can fix the fans – so you don’t have to fiddle around with them after installation. The mounting of these fans is also very convenient, because the fan clamps hold in the holes – without having to hold them. With many competing products, you have to hold them and lock them in place at the same time. Especially if you plan to install the cooler into the case afterwards, you have much less problems due to lack of space.
Scythe realizes this by having small recesses in the cooling tower – through these you can fix the cooler with the included screwdriver. Another positive aspect is that the screws are already fixed to the cooling tower. Models of other brands partly use metal rails, which have to be screwed more complex.
The fan has an overall height of 154.5 mm and is therefore not excessively large. This results in a very good case compatibility, the cooler fits in almost every Midi case. The screws can be completely tightened by the springs – so you don’t have to worry about overtightening the cooler. The connection cables for the fans have a comfortable length, so that you can lay them neatly to the right connector.
For mounting on AMD CPUs, the existing AMD backplate is used, for Intel a suitable backplate was included. The whole manual is easy to understand and there is no point of criticism here.
Performance and temperatures
The workmanship is very good, the assembly runs smoothly – we are not surprised by the performance either. In the test I let the fan compete against an EKL Alpenföhn Matterhorn Pure, as a good 120mm single tower fan and the just released SilentiumPC Grandis 3, as direct competition in the dual tower class for 50 €.
The test system consists of a Ryzen 5 3600, which is enthroned on a MSI X570-A Pro. The whole thing is installed with 16 GB RAM and a GIGABYTE RX 5600 XT GAMING OC in a Fractal Design Define 7. A few Wing Boost 3 ARGB have been provided for good case ventilation. For better comparability, identical thermal compound was used everywhere – in this case the Arctic MX-4.
The test scenario is a high CPU load by Prime95 with the “in-place FFTs” – due to this the load is also constant and gives us comparable values. First of all, it should be said that Ryzen’s 3000 series gets very hot in this scenario. This is due to the 7 nm technology and the resulting hotspots on the heatspreader. In normal gaming mode, the CPU is of course much cooler – even at low speeds. However, this test scenario shows how powerful the coolers are.
I decided to do the tests at 50% PWM and 100% PWM. 50% PWM is a good “everyday value”, where the fans should not be too loud under normal load, but keep the CPU cool enough. We then see the maximum potential at 100% PWM.
On the subject of noise – the Fuma 2 was NOT perceptible from the case at 50% PWM – at 100% PWM it was still very quiet. For comparison – the Matterhorn Pure was already louder at 50% PWM than the Fuma 2 at 100%. In the test, the Fuma 2 was slightly behind the Grandis 3 from the same price segment – but this one has a 140 mm and a 120 mm fan.
