Scythe Mugen 4 High Performance CPU Cooler, SCMG-4000

- Replaced by the Scythe Mugen Max High Performance Quiet CPU Cooler, SCMGD-1000

Introducing the fourth generation of the Mugen CPU cooler from Scythe which now features greater performance and an easier installation compared to previous models.

The next instalment of Mugen provides a three-dimensional multiple airflow pass-through structure fin design, greater compatibility and an easy mounting method. The Mugen 4 comes with a very quiet GlideStream PWM fan (starts at only 5.3 dBA) to minimise the noise level at low load as well as maintaining cooling performance at heavy load.


  1. Greater performance over the Mugen 3
  2. Total of six U-shaped heatpipes
  3. Features TMAPS for better airflow and performance
  4. Extremely quiet, from only 5.3 dBA
  5. Compatible with Intel LGA2011/1366/1150/1155/1156/775 and AMD FM1/AM3+/AM3/AM2+/AM2

T-M.A.P.S. (Three-dimensional Multiple Airflow Pass- through Structure)

The Mugen 4's unique fin structure decreases air resistance and optimises cooling performance in the lower rpm-range of the supplied fan. Furthermore, the smart arrangement of the fin layout made space for one more pair of fins without negatively affecting the total height.

User-friendly Installation

The fundamental change to the Mugen 3 is in the mounting system of the Mugen 4. The new H.P.M.S (Hyper Precision Mounting System) makes easy mounting possible by allowing the Mugen 4 to be fitted without having to remove the motherboard from the case. This reduces the number of steps involved and makes for an easier life!

Multi Fan Mount Structure

Following in its predecessors footsteps, the Mugen 4's design also allows variable fan placement to optimise a targeted airflow. To further enhance cooling performance, a second fan can be mounted with the supplied pair of fan clips.
