Case Fan
The case can support 120mm or 80mm cooling fan. To install the fan in the front, the front bezel
has to be removed first. If both front and rear fans are installed, make sure the air flow is
consistent. Typically, the rear fan is blowing air out of the case and the front fan is blowing air
into the case.
