Fan for Raspberry Pi 4B official case (Raspberry) — compact cooling fan for single-board computer

Fan for Raspberry Pi 4B official case (Raspberry) — compact cooling fan for single-board computer is a purpose-built active cooling accessory designed to fit inside the official Raspberry Pi 4B case. Manufactured by Raspberry, this small fan improves airflow over the CPU and nearby components, helping to reduce operating temperatures during sustained workloads and preventing thermal throttling in compact enclosures used for media playback, server tasks, or continuous IoT operation.

Advantages

This compact fan provides targeted cooling within the official Raspberry Pi 4B case while occupying minimal space. It operates with low power consumption and is engineered to align with the case’s mounting points for straightforward installation. By improving internal airflow, the fan contributes to more stable processor performance under load and can extend the reliable operating range of connected peripherals and storage devices that share the same confined space.

Suitable for

• Media centers and home theater PCs based on Raspberry Pi 4B
• Home servers, file servers and network services running continuously
• IoT and embedded projects requiring enclosed, compact cooling
• Overclocking or CPU-intensive tasks such as software compilation or emulation
• Environments where ambient temperature and limited ventilation demand active cooling

Key specifications

• Designed to fit the official Raspberry Pi 4B case mounting layout
• Compact form factor suitable for small enclosed cases
• Low-voltage operation compatible with Raspberry Pi power rails
• Active cooling that targets CPU and nearby components to reduce thermal throttling
• Minimal additional weight and footprint to preserve portable and compact project designs

How to use

Install the fan in the official Raspberry Pi 4B case by aligning it with the case’s designated mounting points and securing it according to the case instructions. Connect the fan to the appropriate GPIO header or fan connector on the Raspberry Pi 4B as specified by the manufacturer, observing correct orientation for power and ground. Once connected and the system is powered, verify airflow and ensure the fan spins freely without contacting cables or components. Monitor system temperatures during initial use to confirm effective cooling.

Usage recommendations

For consistent thermal performance, use the fan when running sustained workloads, media playback, or network services. Keep intake and exhaust openings free of dust and obstructions. If quieter operation is required, consider controlling fan speed via GPIO-based software or a PWM-capable controller to balance noise and cooling. Periodically check the fan for dust buildup and clean as needed to maintain airflow.
