- Color: Black or Silver (based on availability)
- Number of Pieces: 3-piece kit (CPU, RAM, USB/power chip)
- Mounting: Thermal adhesive pre-applied
- Compatibility: Only for Raspberry Pi 4 Model B
- Dimensions: Precision matched to Pi 4 chip layout
Compatibility and Installation
This heatsink kit is made specifically for the Raspberry Pi 4 Model B. Installation is simple: clean the chip surfaces, peel the protective film from the pre-applied adhesive, and press each heatsink into place. Allow a few minutes for the adhesive to set before powering the board.
Use Cases
- Everyday computing and desktop-style Raspberry Pi 4 setups
- Long-term Raspberry Pi 4 temperature control for always-on projects
- Overclocked Raspberry Pi configurations that need extra cooling headroom
- Quiet cooling for Raspberry Pi 4 servers, media centers, and home labs
