Scythe Kotetsu CPU Cooler: A Compact King

Scythe Kotetsu
CPU Cooler

Scythe took a big step last year with the Mugen 4. It wasn't a particularly revolutionary or even evolutionary design and in fact it was almost identical to its predecessor. However, it was one of the best CPU coolers we've tested, thanks in no small part to an upgraded modern mounting system which we've been suggesting they switch to for years. Its modest composition also made it relatively light and more affordable than much of the high-end competition, and of course Scythe fans are renowned for their pleasant acoustics.

The Kotetsu.

While Noctua, Prolimatech, and Thermalright have gone on to produce some massive dual fan heatsinks during a cooling arms race, Scythe has refrained from participating, preferring to focus on more pragmatic fare. The Kotetsu is one such cooler, essentially a more compact and affordable version of the Ashura, which is a wide tower cooler with a 140 mm fan and six heatpipes. The Kotetsu is smaller in every dimension except height, and is equipped with only a 120 mm fan and just four heatpipes. Its dimensions and shape are similar to dozens of others, which is rare for a Scythe product.

We were somewhat disappointed by the performance of the Scythe Ashura. It wasn't a bad cooling solution by any stretch of the imagination but it was a letdown as a follow-up to the Mugen 4. We suspect its oddly shaped base prevented it from realizing its full potential, and while the Kotetsu base has a similar surface, it appears to have been refined.

The box.


The Kotetsu ships in a modestly sized boxed adorned with color pictures of the product and a few badges touting its various features. Its contents include the heatsink itself, a 120 mm fan, mounting hardware, thermal compound, one set of fan clips, and a brief assembly guide. As per usual, it's compatible with every modern desktop socket and older ones going back 8 years.
