However, the nickel-plated copper base plate is finished exceptionally well:

The base plate is very even. You can only see tiny imperfections at the very corners of it if you use a metal ruler:


Most importantly, the surface is impeccable where it contacts the processor heat-spreader:

Scythe Mugen 2 is equipped with a 9-blade 120 x 120 x 25mm fan from Slip Stream 120 series (SY1225SL12LM-P model):


The fan uses a slide bearing with 30,000 hours MTBF (over 3 years of non-stop operation). The fan rotation speed is PWM controlled from 0 to 1300RPM creating up to 74.25CFM airflow. The maximum level of noise generated by the cooler fan is claimed to not exceed 26.5dBA.

Slip Stream 120 is attached to the heatsink with two wire clips. Their ends get inserted into exterior holes of the fan frame and then the clips click on to special notches on the heatsink:

The heatsink has a total of 8 symmetrical notches, so you can attach up to four fans to it:

In this case, however, you will need to get another 3 fans and three additional retention kits for them.

As you understand, you can install the enclosed fan either along one of the heatsink arrays or across them:


The cooling efficiency will be the highest if the airflow is directed along the arrays. The manufacturer recommends this particular installation, so the only situation when you may need to install the fan differently, is when you can’t attach the retention clips to one of the wide sides of the cooler for some reason.
