The S9 refuses to die, and neither should the effort to make it liveable. This is the S9-specific version of our single-fan shroud: a deeper capture body shaped around the S9 exhaust end rather than a flat plate that merely covers the fan, so the air leaving the chassis has somewhere to go before it reaches the collar.
Designed around the Antminer S9 family exhaust end — S9, S9i, S9j, S9k and S9 SE all share the same chassis footprint and 120 mm exhaust fan. It also suits any machine with the same fan face and a comparable exhaust-end profile. Output is a standard 6-inch duct collar.
Measure before you order. Fit dimensions in this line are derived from published fan and chassis geometry and are not yet validated against measured production hardware. Check your flange size and the clearance around your machine against the footprint in the specifications below. If something does not fit, tell us — that is how the next revision gets better.
Slide it onto the exhaust end of the S9, clamp 6-inch duct to the collar, and you have converted the loudest, hottest end of an old ASIC into a directed heat source. This is the standard first step for anyone turning an S9 into a shop heater, a garage heater, or a machine that can live in a house without owning the room it sits in.
The S9 is the most common home-mining machine on the planet and the most likely to be run somewhere it was never designed for. Ducting the exhaust is what makes that possible — it takes the heat out of the occupied space and gives you somewhere useful to put it instead. The deeper body means less turbulent spill at the corners than a shallow adapter.

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 listing is for the finished part: made to order in PETG and shipped from Montreal, Quebec. If you would rather have it in your hands than spend an evening making one, buy it here — that is what pays for the next design in the line. You can also support the open-source work directly through D-Central’s fund page.

It is designed around the shared S9-family chassis and 120 mm exhaust fan, which covers S9, S9i, S9j, S9k and S9 SE. Fit is not yet hardware-validated across every production batch and aftermarket fan swap in the field, so check your clearance before ordering.
For an S9, yes — the deeper body captures the exhaust end rather than sitting flat against the fan, which means less air escaping around the edges. If you are shrouding a bare fan or a non-S9 build, the universal version is the cheaper, more flexible choice.
That is exactly what most people do with it. Duct the exhaust to where you want the heat and you have a space heater that happens to mine. Read our guide on Bitcoin miner heat reuse before you plumb it into living space — there are real considerations around air quality, noise and backdraft.
A shroud and duct change where the noise goes, and that alone helps a lot. If you want to attack the noise itself, look at the expansion-chamber silencer version of this size, which puts a tuned chamber between the fan and the duct. We do not publish decibel figures because we have not measured them.

When Bitmain announced the Antminer S21, the Bitcoin mining world took notice. After years of incremental improvements across the S19 lineup, the S21 represents a genuine generational leap…
In the rapidly evolving world of cryptocurrency, Bitcoin mining has emerged as a cornerstone activity for enthusiasts and investors alike.
Industrial mining hardware was never built for your house. 3D printing closes the gap — shrouds, enclosures, stands, and repairs. Here is what to print, what to buy, and where the limits are.
