Active Dual-Fan Cooling for Heavy Workloads
This expansion board provides active dual-fan cooling to prevent thermal throttling on your Raspberry Pi under heavy workloads. Compared to passive heat sinks, the dual brushless fans (DC 5V, 0.2A) continuously draw heat away from the CPU and surrounding components. This ensures your board maintains a stable operating temperature even during intensive tasks like running a home server, retro gaming emulator, or AI processing.
Unobstructed GPIO Pin Access
The shield features a complete 40-pin GPIO breakout with clear silk-screen markings, ensuring your development work remains uninterrupted. Unlike standard cooling cases that block access to the motherboard, this expansion board extends the pins upward. You can easily connect jumper wires, sensors, and other modules while the active cooling system runs simultaneously.
Independent Controls and Non-Dazzling LED
Two dedicated onboard switches allow you to control the fans and the bottom-mounted green LED independently. The LED is strategically soldered on the back of the board, casting a subtle ambient glow downward rather than glaring directly into your eyes, making it perfect for night-time operation or transparent case builds.
Technician Tip
Always use the included hexagonal brass standoffs during installation to create the optimal height difference between the expansion board and the Raspberry Pi. Our Sun Cheong Computer Co. Ltd. technicians note that this expanded negative pressure area significantly improves airflow and cooling efficiency. Please allow the fans to run for about five minutes to reach a stable cooling state after booting up your Pi.

FAQ Section
FAQ Section
- Will this expansion board block my access to the Raspberry Pi GPIO pins?No, the board features a complete GPIO pass-through header that extends all 40 pins upward, allowing you to connect jumper wires easily.
- Can I turn off the green LED light if I don't want it on?Yes, the board has two independent slide switches, allowing you to turn off the LED light while keeping the cooling fans running.
- Is this cooling board compatible with the Raspberry Pi 4B?Yes, it is fully compatible with the Raspberry Pi 4B and utilizes the standard 40-pin layout for power and GPIO access.
- Why are the brass standoffs included in the package?The brass standoffs are required to securely mount the board and create a specific height gap, which expands the negative pressure area for better airflow and cooling.
- Can I bring my Raspberry Pi to your Sham Shui Po store to check the fit?Yes, you are welcome to bring your Raspberry Pi setup to our Sham Shui Po retail shop to verify compatibility and clearance before purchasing.
