Warning: M3 x 16mm screws

If you must use M3 x 16mm screws for the 40mm fan, do not overtighten or you may deform the outer panel surface.

Directions

1) Orient the 40mm fan. Take into account both airflow direction and the location of the fan's wiring.

2) Fasten the fan in place with four (4) M3 x 15mm screws.

3) Place the Raspberry Pi on the CPU tray with the headers facing away from the fan.

4) Fasten with four (4) M3 x 6mm screws. The holes are for M2.5 screws but will bore out easily for M3 screws.

5) Slide the assembly into the case. The front CPU bays offer more room for connectors, but any CPU bay work.

6) Install with four screws.
