Scythe Launches the Mugen 4 CPU Cooler
The Mugen 4 CPU Cooler builds on the design of the Mugen 3 and is expected to release later this month.
Scythe has launched the Mugen 4 CPU Cooler, which as one might expect, iterates on its predecessor and features the same "jagged aluminum fin" design with six 6 mm copper heatpipes conveying heat from a nickel-plated copper base.
The CPU cooler features the company's new Hyper-Precision Mounting System (HPMS) which requires fewer steps to install and has support for all modern CPU sockets, including the LGA1150 socket utilized by Intel's upcoming Haswell processors. Scythe has also modified the fin-stack arrangement to incorporate a "three-dimensional multiple airflow pass-through structure" (TMAPS) that aims to improve air-flow and heat dissipation.
The Mugen 4 measures 130 x 88 x 160 mm, weighs 625 g and features a Falcon 120 mm PWN fan that is capable of moving between 20.7 CFM (400 RPM) and 79 CFM (1,400 RPM) of air.
The Scythe Mugen 4 is expected to release in Japan on April 24, 2013 with a retail price of 4,980¥ ($50).

But I have to note that I have had two builds come in with problems in the last cupla months whereby the Memory OK Red LED was On. I traced the problem in both instances to scored motherboard surfaces (interrupting printed circuits) from the standoff screws for Hyper 212 installations. I never had the problem on builds I have done but I added thin textile or plastic washers under the standoffs (these don't come with the kit).
