Official RPi4 Case Addon PWM Cooling Fan & Heatsink

Note: This is the add-on cooling fan and heatsink only, the official case is NOT included. If you want to get the full case with the cooling fan and heatsink, get it from here:

• Official RPi 4 Model B Case with Case Fan (Red/White)
• Official RPi 4 Model B Case with Case Fan (Black/Grey)

Now, the most powerful Raspberry Pi, Raspberry Pi 4 Model B can stay cool in the official case :) This is the case fan for the official case of the Raspberry Pi 4 Model B board.

Check out this video on how you can set up the Fan with RPi4 Case in 5 simple steps!

This case fan is specially designed for the official case of Raspberry Pi 4B and there are officially from the Raspberry Pi team, compatible with both the:

• Red/White Case
• Black/Grey Case

It is a snap and fit case fan, with NO screw or nut needed or hacking to integrate it into the official case. Nice!

It also comes with an adhesive heatsink for you to paste on the BCM2711 CPU of Raspberry Pi 4 Model B, further keeping the board cool!

Did I mention? The cooling fan is PWM controllable from Raspberry Pi OS. By default, the fan will start spinning right after the Raspberry Pi 4 Model B is powered. If temperature-controlled fan activation is needed, some configuration is needed. Anyway, just make sure to update the Raspberry Pi OS.

Since it is PWM controllable, there is an extra wire needed besides the RED for 5V(pin 4) and BLACK for the GND (pin 6). The additional BLUE wire should be connected to pin 8 of Raspberry Pi's GPIO.

Now, using the Raspberry Pi 4 Model B single-board computer in the official case will be worry free! Check out the following graph of temperature performance under stress-test (Stressberry) in different conditions: CPU clocking at 1.5GHz

• Red - Raspberry Pi 4 Model B with 3 heatsinks (CPU, RAM, and USB Controller), in the official case (Red/White), no additional fan
• Blue - Raspberry Pi 4 Model B, bare board, no heatsink and not in any case/enclosure
• Orange - Raspberry Pi 4 Model B with 3 heatsinks (CPU, RAM, and USB Controller), not in any case/enclosure
• Green - Raspberry Pi 4 Model B with the only heatsink on CPU, in the official case (Red/White) and the add-on case fan

As the chart shows, the case fan will keep the Raspberry Pi cool in the official case under full load test :)
