The heatsink is topped with a 120-mm fan. It cools not only the entire thing, but also lowers the temperature of the components around the CPU socket, unlike the tower-coolers:
The nickel-plated cooler base is covered with special film protecting the base surface from scratches other physical damage. And actually, there is a lot to protect...
The evenness of the base plate and its finish quality are on unattainably high level for most other makers:
The imprint of the thermal interface applied to the processor heat-spreader looks as follows:
Scythe Kabuto is equipped with exactly the same fan as Mugen 2 – a nine-blade Scythe Slip Stream 120 with PWM rotation speed control (SY1225SL12LM-P model).
The fan is built with a slide bearing with 30,000 hours or more than 3.4 years MTBF of non-stop operation.
The fan rotation speed varies automatically in the interval between 200 and 1300 RPM at 74.25CFM airflow. The noise level from the fan shouldn’t exceed 26.5dBA.
The fan is fastened very securely with two wire clips inserted into special holes in the heatsink.
The ends of these clips go into the internal fan holes, so if you decide to replace the default Slip Stream 120 with something else and don’t want to invent an alternative retention for it, make sure that the fan you pick doesn’t have spindles instead of holes (SilverStone FM121, Scythe Gentle Typhoon).
This is pretty much all we can tell you about the cooler. Let’s move on to the installation techniques.
