Heavy Fucking Duty Heat Sink for CB1
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
