The Scythe Mugen 4 was introduced some time back, and at the end of this month it should finally be in stores. For years the original Mugen and especially the Mugen 2 were the most popular coolers on Hardware.Info due their outstanding cooling, low noise and affordable price. When the Mugen 2 was phased out and replaced by the Mugen 3, not everyone was happy. The Mugen 3 was basically a lower-cost version of the Mugen 2, and didn't perform as well in our tests. The Mugen 3 PCGH Edition made up for this by using two fans that were much more silent, but it was more expensive than the Mugen 2. At the same time the competition was getting stronger, and especially Cooler Master has been doing its utmost to create a Scythe-killer.
The Mugen 4 is the latest version, and one thing is clear. The pricing is again the same as that of the older models, as the distributor ensured us that the new Mugen 4 will be available for about € 36, roughly the same price as the excellent Cooler Master Hyper 412S that did so well in a recent test.
The Mugen 4 is again a tower cooler, and it has six 6mm heatpipes that are connected to an aluminium heatsink. The finish of the heatpipes on top is very nice. The fan is a 120mm model that spins between 400 and 1,400 rpm and is equipped with a 4-pin PWM connector. There's room for a second, optional fan as well.
The Mugen 4 weighs 753 grams which means it contains less metal than the previous versions. As you can see in this comparison table, the Mugen 1 weighed 968 grams, the Mugen 2 weighed 870 grams, the Mugen 3 weighed 846 grams and the Mugen 4 weighs even less.
The Mugen 4 is compatible with all current AMD and Intel sockets.
