  • Uses existing fan screws for tool-free installation
  • Compatible with multiple Antminer models including S9, T9, L3+, D3
  • Two-piece set enables dual-fan ducting configuration

Fan duct for Antminer 120mm cooling

This 3D-printed ABS shroud replaces the standard fan guard on compatible Antminer models using the existing screws. It channels exhaust airflow directly into a four-inch vent hose to lower operating temperatures and improve mining efficiency. The thermoplastic material withstands the sustained heat generated by mining hardware. Supplied as a pair for dual-fan configurations.

For miners venting heat through ducting

Suits operators who need to route hot exhaust from Antminer S9, S9i, E3, T9, V9, X3, L3+, D3 or A3 units into a four-inch hose system. Not suitable for the Antminer S7 single-fan design because the mounting pattern differs. Buyers who require the vent hose or clamps must source those separately.

120mm fan mounting compatibility

The duct fits any standard 120mm fan frame using the original mounting holes, so installation needs no new fasteners or adapters. This single dimension determines whether the shroud will attach to your specific miner or custom cooling setup.

Questions about this item

Does the ABS plastic shroud soften or deform when the Antminer exhaust runs hot all day?

The duct is 3D-printed from ABS thermoplastic chosen specifically to withstand the high exhaust temperatures produced by mining equipment without softening.

How much extra fan noise or airflow restriction does the duct add during continuous operation?

The shroud replaces the standard fan guard using the existing screws and is shaped to keep air moving freely, so it adds no measurable restriction or noise beyond the stock fan.

Which mounting hardware must already be on the miner for the shroud to attach?

The duct uses the four standard 120 mm fan mounting screws already present on compatible Antminer models; no additional brackets or fasteners are required.
