4. Guia d'instal·lació
Follow these steps to properly install the Radxa Heatsink 4025A on your ROCK 5B/5B+/5T board:
Step 01: Apply Smaller Thermal Pad
Attach the 22 x 22 x 0.8 mm thermal pad directly to the System-on-Chip (SoC) on your Radxa board. Ensure it is centered and makes good contact with the SoC surface.

5. Funcionament
The Radxa Heatsink 4025A is a passive cooling solution. Once installed, it operates continuously to dissipate heat from your Radxa ROCK SBC. No additional configuration or power is required for its basic function. Ensure adequate airflow around your SBC for optimal cooling performance.
6. Manteniment
- Neteja: Periodically inspect the heatsink for dust accumulation. Use a soft brush or compressed air to gently remove any dust from the fins to maintain optimal heat dissipation.
- Inspecció: Ensure the heatsink remains securely fastened to the board. If it becomes loose, re-press the plastic pins to secure it.
- Thermal Pads: The thermal pads are designed for long-term use. If the heatsink is removed and reinstalled, or if you notice a significant drop in cooling performance, consider replacing the thermal pads.
7. Solució De Problemes
- Issue: Board is still overheating after heatsink installation.
- Comprovació de la instal·lació: Ensure the heatsink is firmly attached and makes good contact with the thermal pads and SoC.
- Thermal Pad Placement: Verify that the thermal pads are correctly positioned on the SoC and adjacent components.
- Flux d'aire: Ensure your SBC enclosure or environment provides sufficient airflow around the heatsink. Restricted airflow can hinder passive cooling.
- Temperatura ambiental: Operating in a very hot environment may exceed the passive cooling capabilities. Consider active cooling solutions if necessary.
- Issue: Heatsink feels loose.
- Re-secure Pins: Gently press down on the plastic spring fasteners until they click into place, ensuring a tight fit.
