Mugen 2 rev. B (SCMG-2100)
The second revision of the Scythe Mugen 2 cooler (SCMG-2100) was released quite a long time ago but we haven’t been able to get a sample to test until now. The box is designed in such a way that your eye focuses on the letter B which denotes the new revision.
The kit includes a new back-plate and screws with nuts.
The heatsink is almost the same as the heatsink of the first revision.
The connecting pieces between the heatsink sections have become wider.
There are no grooves for heat pipes in the cooler’s base. Perhaps they will be implemented in the third revision. The cooler’s sole is ideally finished and flat.
The key innovation of the new Mugen 2 is the Flip Mount Super Back-Plate 2 with support for LGA1156 processors. The Ninja 3 is installed in the same way. You attach the steel fastening plates to the cooler’s base:
If you are installing the cooler on an AMD processor, the fastening plates already have threaded holes. For Intel LGA775, LGA1156 and LGA1366 processors you use the same fastener and insert figured pins into the openings and fix them with nuts.
Now you don’t have to unfasten the default back-plate from the mainboard because the cooler’s back-plate wraps the latter (and the back-plate of the Ninja 3 just lies above the default back-plate).
The cooler is secured with screws on the reverse side of the PCB. It is easier to turn the cooler upside down and put the mainboard on it.
The pressure is high and the steel fastening is absolutely reliable.
The Mugen 2 should be oriented in such a way that its heat pipes ran across the CPU (as in the right photo):
In this position the top temperature of the hottest core of our LGA1366 processor was 3°C lower than when the heat pipes ran along the heat-spreader. Things may be different with AMD processors but we didn’t check this out.
The Scythe Mugen 2 revision B comes at a recommended $60 but its retail price can be as low as $50.
