The correct shroud for dual-140mm Antminer exhaust
This PETG shroud captures the main heat leaving two stock 140mm Antminer exhaust fans and combines it into one standard 8-inch duct connection. It uses the miner’s stock fan screws and does not require a separate mounting kit.
Fit rule: This design fits every Antminer model that uses two 140mm exhaust fans. Measure the outer fan frame edge-to-edge; choose this product only when it is approximately 140mm. This product does not capture PSU exhaust.
Purpose-built around the larger fan frame
True 140mm geometry
This is not the dual-120mm adapter resized at the duct. The mounting side is designed for two 140mm exhaust fans.
One 8-inch outlet
Both ASIC exhaust fans feed a single round connection for routing heat out of the mining space.

Frequently asked questions
How do I know whether my fans are 120mm or 140mm?
Measure the square outer fan frame from one edge to the opposite edge. Choose this page only when the frame is approximately 140mm.
Which Antminer model names does this fit?
Compatibility is determined by the hardware. If your Antminer has two 140mm exhaust fans, this is the correct 8-inch design.
Does it capture PSU heat?
No. It routes the main dual-fan ASIC exhaust only.
Are ducting and clamps included?
No. The listing is for the PETG shroud. Supply the 8-inch duct and clamp appropriate for your installation.
Installation note: Never work on an energized miner. Keep duct runs open and supported, avoid sharp restrictions, and monitor temperatures and fan behavior after any airflow change.
Not sure whether your fans are 120mm or 140mm?
Use the CryptoCloaks ASIC Shroud Finder and measure the fan frame before ordering.

Excellent quality exhaust shrouds for dual 140mm fans on an Antminer s21XP. I was able to use the stock 45mm M4 screws to secure the shroud.
