Whatsminer 140 mm Fan to 8″ Duct Shroud

Description

Overview

The 140 mm Whatsminer shroud with an 8-inch outlet. If you are going to duct a machine that moves as much air as an M-series does, this is the size that stops the duct being the bottleneck.

What it fits

Same M-series 140 mm fan flange intake as the 6-inch version, dimensioned to the bare fan rather than a generation-specific chassis wrap. Output collar takes standard 8-inch flexible or rigid duct and mates with 8-inch inline fans.

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.

How it is used

This is the version to use on long runs, on runs with several elbows, or where the Whatsminer feeds a shared exhaust trunk with other machines. It is also the right choice if you are pairing the machine with an 8-inch inline booster fan rather than relying on the ASIC fan alone.

Why it helps

Duct diameter is the cheapest airflow you will ever buy. Every elbow and every metre of flex duct takes pressure away from the fan, and a machine running at full power is not in a position to donate any. Starting at 8 inches means the restriction budget gets spent on the run, not on the very first fitting.

  • 140 mm Whatsminer fan face to full 8-inch collar
  • Sized for long runs, multi-bend routing and shared trunks
  • Mates directly with 8-inch inline booster fans
  • Single continuous body, no assembly

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 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.

Frequently asked questions

When is 8-inch worth it over 6-inch?

When the run is long, when it has more than one or two bends, when several machines share a trunk, or when an 8-inch inline fan is in the path. On a short straight shot out a nearby wall, the 6-inch version is smaller, cheaper and perfectly adequate.

Can I step down to 6-inch at the wall?

Yes. Run 8-inch for the length of the trunk and step down at the penetration with an 8″ to 6″ reducer. Reducing at the end of the run costs you much less than reducing at the start.

Does this fit the M30S / M50S / M60S?

It is dimensioned to the shared M-series 140 mm fan flange, so it should carry across those generations. Fit is not yet hardware-validated on every model, so measure before ordering — and the file is open if you need to adjust it.
