Official Raspberry Pi 4 Case Fan
The Raspberry Pi 4 Case Fan works with Raspberry Pi 4 and the Raspberry Pi 4 Case. Designed for overclockers and other power users, it keeps your Raspberry Pi 4 at a comfortable operating temperature even under heavy load.
The temperature-controlled fan delivers up to 1.4 CFM of airflow over the processor, memory, and power management IC. The bundled 18mm × 18mm × 10mm heatsink with self-adhesive pad improves heat transfer from the processor.
• Fits perfectly into the lid of the Raspberry Pi 4 Case
• Temperature-controlled fan delivers up to 1.4 CFM of air flow over the
processor, memory, and power management IC
• 18 mm × 18 mm × 10 mm heatsink with self-adhesive pad improves heat
transfer from the processor

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
5 Fit the lid of the case onto the base.
