Bitaxe Cooling Solutions: Complete Thermal Management Guide
Every ASIC chip is a furnace in miniature. The BM1366 and BM1370 chips inside your Bitaxe are computing trillions of SHA-256 hashes per second, and every single hash generates heat.
AC Infinity Cloudline Duct Coupler (4″ / 6″ / 8″)
Priced by quote
A direct coupler between AC Infinity Cloudline inline fans and the rest of the ducting line. Cloudline fans are the default inline booster in home mining and home growing alike, and mating them cleanly to a shroud currently involves more tape than anybody is happy about.

Description
In development — not yet available to order. Waiting on a verified coupler outside-diameter measurement from a physical Cloudline unit. We will not publish a fit dimension we have not held in our hands.
Overview
A direct coupler between AC Infinity Cloudline inline fans and the rest of the ducting line. Cloudline fans are the default inline booster in home mining and home growing alike, and mating them cleanly to a shroud currently involves more tape than anybody is happy about.
What it fits
Planned for the Cloudline S-series and T-series housings in 4-inch, 6-inch and 8-inch, coupling to our standard duct collars on the other side.
How it is used
It will sit between a shroud or duct run and the Cloudline housing, giving a positive, clampable joint instead of a friction fit wrapped in foil tape.
Why it helps
The Cloudline is the inline fan most people reach for when the ASIC fans alone cannot push the run, and the joint between it and everything else is the weakest link in most home installs. This part exists to fix that.
- Planned in 4-inch, 6-inch and 8-inch to match the Cloudline range
- Positive clampable joint in place of a taped friction fit
- Will connect directly to the standard collars used across the line

Open source — print it yourself, or buy it finished
Every shroud D-Central designs is released as an open file. The geometry for this part is free to download from our 3D models download center: use it, modify it, remix it, run it in your own shop, sell what you make from it. There is no licence to buy and no design gated behind a purchase. Shared knowledge is the whole reason this industry has open hardware at all, and we are not going to be the ones who stop passing it on.
This part is not finished yet, so there is no file to download and nothing to buy. When it is done, both arrive at the same time — the file free, the finished part for sale. If the open-source work is worth something to you in the meantime, you can back it directly through D-Central’s fund page.

Frequently asked questions
When will it be available?
When we have measured a physical Cloudline housing. The design is straightforward; the outside diameter is not something we are willing to take from a forum post. Publishing a fit dimension we have not verified is how people end up with a part that does not fit.
Can I get the file early?
Every shroud file we ship is published free at our 3D models download center, and this one will be too once the geometry is confirmed. If you own a Cloudline and can measure the coupler OD accurately, we would genuinely like to hear from you.
