Overview
The Raspberry Pi 4 Case Fan is an ocial accessory for Raspberry Pi 4, for
use with the ocial Raspberry Pi 4 Case. Designed for over-clockers and
other power users, it keeps your Raspberry Pi 4 at a comfortable operating
temperature even under heavy load.

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 rmly 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 ush with the underside of the lid.
3 If you are also tting 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.

WARNINGS
• This product should only be used in conjunction with Raspberry Pi 4 Model B and the ocial Raspberry
Pi 4 Case.
• This product should be operated in a well-ventilated environment and the case should not be covered.
SAFETY INSTRUCTIONS
To avoid malfunction or damage to this product, please observe the following:
• Do not expose to water or moisture, or place on a conductive surface whilst in operation.
• Do not expose to heat from any external source; the Raspberry Pi Case Fan is designed for reliable
operation at normal ambient temperatures.
• Take care whilst handling to avoid mechanical or electrical damage to the fan and connectors.
• Avoid handling the fan whilst it is powered.
