The Scythe Mugen-2 is the updated version of the Mugen (AKA Infinity) CPU cooler. At the time of its release, the Mugen was an excellent heatsink, able to cool most of the processors of its day with little airflow. Unfortunately the Mugen coexisted with the better performing Scythe Ninja, which took most of accolades. The heatsink itself has had some interesting design improvements and now comes with a 120mm PWM fan. Most importantly, this big heatsink sports a simple bolt-thru installation procedure. It is Scythe's first serious departure from stock Intel plastic push-pins in many years.

While Scythe practically invented the massive CPU heatsink, most of them use stock LGA775 pushpin and AMD tension-clip mounts. These mounting methods are fine for regular-sized coolers, but peace of mind quickly goes out the window in the face of gravity acting on a 15-16cm tall aluminum/copper tower weighing almost 1kg and sitting on a processor worth hundreds of dollars. With the Mugen-2, installation on any of the compatible sockets requires the heatsink to be bolted down with steel machined screws to a spider-like steel backplate. This is a major improvement over plastic push-pins and stock mounting clips.

Feature & Brief
Our Comment
F.M.S.B. (Flip Mount Super Back-Plate)
The newly developed F.M.S.B. (Flip Mount Super Back-Plate) both improves the compatibility and mounting of the cooler with the motherboard. With this system, a solution was developed which is not using push pins but is instead based on a Back Plate/screws mounting set. Of course, Mugen-2 is compatible with all the current sockets, including the new Intel Socket LGA1366.
The Mugen-2 is the first Scythe CPU cooler to feature a straight bolt-thru mounting design. A single backplate offers hard mounting for all modern Intel and AMD sockets.
Multi Fan Mount Structure
As with the former Mugen it is possible to mount the supplied fan in four different directions. By this, the user can arrange the air flow to the circumstances of his deployment area. Furthermore, a maximum of 4 fans be installed, the needed fan clips have to be bought separately.
Like the Ninja series, fans can be installed on all or any of the four sides. The Mugen-2 is not a perfectly square heatsink, though, so fans placed on the narrow sides will not perform as well.
M.A.P.S. (Multiple Airflow Pass-Through Structure)
The newly developed M.A.P.S. (Multiple Airflow pass-through structure) is a completely new lamellar structure, where the airflow generated by the Scythe Slip Stream 120 mm PWM fan can be used perfectly
Mugen-2 has a series of slits running down the length of its mass, effectively splitting the fins in into five columns. This feature has been implemented to reduce resistance to airflow.
