Fitting instructions

1 Remove any SD card, then put your Raspberry Pi into the lower half (base)

of the case. Take care to align the mounting holes in the corners with the

bumps in the case.

2 Insert the fan into the upper half (lid) of the case, with the green label facing

away from the lid. Push gently but firmly so that the two tabs on the fan

housing click neatly into place inside the tabs on the lid. The slightly curved

edge of the housing should be flush with the underside of the lid.

3 If you are also fitting the heatsink, remove the backing paper from the

self-adhesive pad on the base of the heatsink, position it centrally over the

processor, and gently press it into position.

4 Connect the three leads from the fan to the Raspberry Pi 4’s GPIO pins, as

shown in the table and diagram below. Take care to connect each lead to the

correct pin.
