Raspberry Pi 4 Case Fan

by Raspberry Pi

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.

Features

  • Fits perfectly into the lid of the official Raspberry Pi 4 Case
  • Temperature-controlled fan delivers up to 1.4CFM of air flow over the processor, memory and power-management IC
  • 18mm × 18mm × 10mm heatsink with self-adhesive pad improves heat transfer from the processor

Specification

  • Input voltage: 5V DC supplied via 40-pin GPIO header on Raspberry Pi 4
  • Fan speed control: Pulse width modulation control via user-selectable GPIO pin
  • Maximum airflow: 1.4CFM
  • Case Material: Clear PC
  • Compliance: For a full list of local and regional product approvals please click here. 

Fitting Instructions

  1. Insert Raspberry Pi 4 unit into the lower half (base) of the case, taking care to first remove any SD card, and to align the connectors with the apertures in the base.
  2. Insert the case fan into the upper half (lid) of the case, with the fan pointing away from the lid. The two tabs on the fan housing should fit neatly into the inside of the tabs on the lids, and 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 selfadhesive pad on the base of the heatsink, position it centrally over the processor and gently press it in position.
  4. Connect the wires from the fan to the Raspberry Pi 4 40-pin GPIO header as below
  5. Assemble the case.

I bought two fans. One of the fans doesn't seem to work properly, perhaps a little infant mortality. That sometimes happens and I don't hold that against Pimoroni, not their fault. I haven't pursued a replacement yet because I haven't finished testing to confirm it is dead. For the working fan, it does a very good job of keeping the Pi 4 cool. One thing I would love to see improved is the wiring. You get three wires that go to two connectors that slide onto pins on the Pi. I would prefer to have it all on one connector. But that is a minor complaint. Installation of the fan into the case is very easy, it just snaps into place. Connecting the fan to the Pi is easy, just slide the three wires onto specific pins on the pin header in accordance with very clear directions. The fan also comes with a heat sink that goes on the CPU and helps with heat dissipation.

Easy to install, software support out the box, remarkably noisy on any of the speed settings when installed in the case. Does the job, but not for a quiet room or bedroom.

Small but effective fan, less noisy and does the job. I have read and watched reviews about this fan, but buying and installing was fun and it does the job effectively. The temperature has remained normal between 40 to 45 degrees.

The Pi 4 fan kit is very simple to install, and provides a simple and cheap way to keep your Pi running at its best.

Very efficient fan which combined with the heatsink does the job really well. Noisy-ish considering the size. Once the Fan Control Pin is enabled on the Pi, it barely turns on, so not really a problem.

Fits nicely inside the official case, but since the case has no vents at all it's hard to see how it's going to cool the board properly.
