Purpose-built cooling shroud

This 3D-printed ABS duct replaces the standard fan guard on compatible Bitmain Antminer units. It channels exhaust directly into a 4-inch vent hose to lower operating temperatures and improve mining stability. The pack contains six shrouds for multi-unit rigs.

120 mm fan compatibility

Each shroud mounts to a standard 120 mm fan using the existing screw holes, so no new hardware or modifications are required. The design is verified for Antminer S9, S9i, E3, T9, V9, X3, L3+, D3 and A3 models, but will not fit the single-fan S7 variant.

Hose-ready exhaust

The 4-inch outlet accepts common vent hose and a clamp (neither included), letting builders route hot air out of the rack or room immediately. Because the shroud is printed in ABS, it withstands sustained high exhaust temperatures without deforming.

Questions about this item

How does the 120 mm fan duct affect temperatures inside an Antminer?

The duct replaces the standard fan guard and channels airflow directly into a four inch vent hose, removing hot exhaust air from the miner and lowering internal temperatures.

What hose standard does the duct connect to and what does that limit?

The outlet is sized for standard four inch vent hose, so maximum airflow is capped by the hose diameter and any bends or length you add.

Which mounting points does the shroud use on the miner?

It attaches with the existing screws that hold the 120 mm fan guard, requiring no new holes or brackets.
