Raspberry Pi Fan HAT – Active Cooling for Raspberry Pi 4
The Raspberry Pi Fan HAT is an active cooling fan specifically designed for the Raspberry Pi 4, reliably cooling the processor and preventing performance drops due to overheating. The module simply plugs onto the GPIO header and requires no separate power supply.
Effective active cooling prevents throttling even under intensive workloads
Easy installation directly onto GPIO pins – no soldering or screwing required
Quiet operation with sufficient airflow for daily use
Compact form factor fits most standard Raspberry Pi 4 cases with fan opening
What sets the Fan HAT apart
Unlike passive heatsinks, the Fan HAT uses active airflow to dissipate heat – ideal for projects with sustained high CPU load such as media centers or NAS systems. The design is tailored to the Raspberry Pi 4 and utilizes the GPIO pins without additional adapters.
Ideal for...
Raspberry Pi 4 users running compute-intensive tasks: retro gaming, video streaming, AI inference, home server, or 3D printer control. Even in tight enclosures without natural convection, the fan ensures stable operating temperatures.
How to use the Fan HAT
Carefully place the module onto the 40-pin GPIO header of the Raspberry Pi 4 – ensuring correct orientation. Connect the fan cable to the designated socket on the HAT. If using a case, position the fan opening over the CPU. After boot, the fan is automatically powered via GPIO voltage.
Raspberry Pi is a British manufacturer of single-board computers. The foundation develops hardware and software to promote digital education and make computing accessible to everyone.
The Fan HAT is an active cooling module designed specifically for the Raspberry Pi 4. It plugs onto the GPIO header and provides additional cooling to the processor.
No, the Fan HAT is designed only for the Raspberry Pi 4. The GPIO pinout and power supply are optimized for this model.
The Fan HAT is compact and roughly matches the footprint of the Raspberry Pi 4. Exact dimensions are not specified, but it fits most standard cases with a fan cutout.
Yes, the Fan HAT is designed for use inside a case. Ensure your case has an opening above the CPU position to allow air intake.
The fan operates with low noise. The exact noise level is not specified, but it is quieter than typical 40mm fans and suitable for use in living spaces.
