8.3.2 Fan Inlet/Outlet

Inlet/outlet fans 1, 2, 3, 4, 5 are all axial-flow fans which operate by increasing the pressure of air flowing
through it.
These are rotary fans connected to PCB main and driven directly from the FPGA. There are five axial fans
(119x119x25) in the system: 2 pcs on right side of unit cooling two radiators for laser cluster and 3 at the rear
of unit where 1 cools DMD radiator and the final 2 fans are standalone fans providing a cooling airflow to vent
heat out of the system.
