Core i7 against Scythe

Katana III

Katana III is also a newly developed unit. The smallest of the pieces inspected so far. Apart from its name, almost nothing resembles its predecessor, as the shape, size, and inclination of the rib have also changed. The designers also replaced the sole, which added a larger heat dissipation surface than the previous version.

The Katana, although not too large, has been given six heat-conducting tubes, which is a considerable amount for a rib of this size, perhaps a little exaggeration as well. Of course, a lot of tubes certainly don’t hurt performance, in fact. The rib belongs to the set design anyway, ie in this case the fan is almost perpendicular to the motherboard. It is only close because the pipes holding the slats and the fan are bent at roughly 35-40 degrees, so the motherboard also gets some of the cooling air flow.

Due to its small size, the new Katana got a 9-centimeter fan that is PWM-controlled. Speeds can range from 300 to 2500 rpm, while air delivery is 6,7 to 55,55 cubic feet and noise production is 7,2 to 31,07 dBA. At high altitude, therefore, the cattle cannot be called quiet in the slightest, but the weight of only 495 grams compensates for this deficiency. Dimensions are 94 × 108 × 143 millimeters. In terms of supported processors, it is in complete agreement with Kabuto.

Mugen 2

Mugen is one of Scythe’s best-sounding names. One of the first pieces in the new series, we remember, was the first of the Japanese company’s products to receive Core i7 support.
The construction of the rib is similar to the traditional first generation Scythe ribs, meaning the fan is perpendicular to the motherboard. What makes it different, however, is that the slats in this refrigerator are also made according to the new ideas, ie they do not consist of a large block, but of five unconnected pieces. For the lamella bundles, a tube transports the heat piece by piece. However, this tube leaves the base in two directions, so that the bundles reach two ends of the tube. Short head count, we find a total of 5 tubes, which due to the design means 10 ways to dissipate the heat generated in the processor.

The Mugen 2 is more full-bodied than the Katana III, as evidenced by the fact that a 12-centimeter fan is working on it. In this case, the air drive is also PWM-controlled, its speed can vary between 200 and 1300 rpm, depending on the heat generated by the processor. Here, too, we find zero positions, but the minimum here is also 200, as with the Kabuto fan. The air transport in Venti can be between zero and 74,25, while the noise generated can vary between zero and 25,5 dBA as a function of speed.

The 130 × 60 × 156 millimeter rib weighs nine hundred grams including the fan. What is definitely worth highlighting in connection with the product is that the fan can be mounted on any side of the rib, so it is even conceivable to mount 1-1 vent on the opposite side, thus improving the efficiency. The range of processors supported, as it is a new generation product, is the same as Katana III.
