Antminer 120mm Fan Duct for 4 Inch Vent Hose

This 3D-printed ABS shroud replaces the standard fan guard on compatible Antminer models using existing screws. It channels exhaust into a 4 inch vent hose to lower operating temperatures and support sustained mining efficiency. The duct fits a 120mm fan frame and is manufactured in the USA by MG3D Designs.

Suits miners venting heat through ducting.

The shroud works with Antminer S9, S9i, E3, T9, V9, X3, L3+, D3 and A3 models that use a standard 120mm fan layout. It will not fit the Antminer S7 single fan design. Builders needing a different hose diameter or a non-ducted cooling approach should consider other solutions.

No hose or clamp included; ABS handles mining heat

The package contains one duct shroud only — vent hose and clamp must be sourced separately. ABS thermoplastic resists the high temperatures produced by mining hardware, unlike PLA which can soften and pose a fire risk. Colour may be black or blue depending on stock.

Questions about this item

Will this shroud attach to the 120mm fan on my Antminer S9 using the screws already on the unit?

Yes, the duct is designed to fit standard 120mm fans and installs with the existing screws, replacing the fan guard directly.

Can I use this duct on an Antminer S7 that has a single fan design?

No, the product notes state it will not work with the Antminer S7 single fan design; it is intended for dual-fan models such as the S9, S9i, E3, T9, V9, X3, L3+, D3 and A3.

After fitting the shroud, how can I confirm air is moving through the 4-inch vent hose as intended?

You should feel steady airflow at the hose end and see lower reported temperatures on the miner's dashboard compared with the open fan guard.
