Passive cooling for BIGTREETECH CB1 compute-module builds. This black aluminum heatsink is the simple add-on for keeping a CB1 module cooler in Klipper electronics stacks that use Manta boards or a Pi4B-style adapter.
Why use the dedicated CB1 heatsink?
- Board-specific coverage: sized for the CB1 compute module instead of a generic stick-on Raspberry Pi sink.
- Passive, silent cooling: no fan wiring, no extra noise, and no firmware changes.
- Manta ecosystem fit: intended for CB1 installations on boards such as the BTT Manta M8P and BTT Manta M5P.
Specifications
- Brand: BIGTREETECH / BTT
- Part: CB1 heatsink / passive heat sink cooler
- Material: black anodized aluminum
- Approx. heatsink size: 30 × 30 × 10 mm
- Mounting: thermal interface pad/tape and screw-mounted retention, hardware typically included with the heatsink kit
- Use case: CB1 compute modules running Klipper in 3D-printer control electronics
Fitment notes
- Use this for BIGTREETECH CB1 builds, including Manta-style controller stacks and Pi4B Adapter setups.
- BIGTREETECH notes that the newer CB2 does not use the CB1 heatsink; do not buy this as a CB2 cooler.
- Some boards and cases vary in standoff/thread hardware. Check your board hardware before forcing screws.
What it is not
- Not a CB1 compute module, control board, fan, or full electronics kit.
- Not a universal Raspberry Pi CM4 heatsink; thermal contact depends on the carrier and module stack.
