ALLNET Radxa Active Heatsink with Fan for Rock 5B (RDX-FAN-4012-WHITE)

Keep your Radxa Rock 5B running cool under load with this active cooling solution. The 40 mm PWM fan spins up to 8000 RPM, delivering 9.7 CFM airflow while staying under 28.5 dBA.

Overview

The ALLNET RDX-FAN-4012-WHITE is an active heatsink with fan designed specifically for the Radxa Rock 5B single-board computer. It combines an aluminum heatsink with a 40 mm DC brushless fan for efficient heat dissipation. The fan uses a 4-pin PWM connector, allowing the Rock 5B to adjust fan speed based on temperature. A pre-applied thermal pad ensures good thermal transfer between the heatsink and the SoC.

What stands out

• PWM speed control for automatic, quiet operation
• High airflow of 9.7 CFM at only 28.5 dBA
• Pre-applied thermal pad for easy installation
