  • Helps maintain lower operating temperatures on supported miners
  • Mounts to standard 120mm fans using existing hardware
  • Constructed from ABS thermoplastic rated for high-temperature environments
  • Compatible with S9, S9i, E3, T9, V9, X3, L3+, D3 and A3 models

Fan Duct for Antminer Models

This 3D-printed ABS shroud replaces the standard fan guard on compatible Bitmain Antminer units including the S9, S9i, E3, T9, V9, X3, L3+, D3 and A3. It attaches using the existing 120mm fan screws to direct exhaust into a 4-inch vent hose. The single-piece design is manufactured in the USA by MG3D Designs.

Thermals and Noise

The duct channels hot air directly into a 4-inch vent hose so heat leaves the immediate area instead of recirculating. By keeping exhaust flow focused, it helps lower internal temperatures during continuous mining operation. No fan or power supply is included, so acoustic output and power draw remain unchanged from the stock configuration.

What the Accessory Changes

Installation swaps the original fan guard for the duct without additional hardware, creating a sealed path to external venting. The ABS material withstands the high temperatures produced by mining equipment, unlike PLA alternatives that can deform. The package contains four shrouds; the 4-inch vent hose and clamps must be sourced separately. It does not fit the single-fan Antminer S7 design.

Questions about this item

How do I install this fan duct on my Antminer's 120mm fan?

Remove the existing fan guard, align the duct with the fan's screw holes, and reattach using the original screws. The design fits standard 120mm spacing so no new holes are needed.

Will the ABS material degrade or need replacement from the miner's exhaust heat?

ABS is a durable thermoplastic chosen for high-temperature resistance. It handles sustained mining heat without warping, so routine replacement is not expected under normal operation.

At what point does the 4-inch hose connection become the airflow bottleneck?

The duct's outlet matches a standard 4-inch vent hose. If the hose runs too long, adds sharp bends, or uses a restrictive clamp, static pressure rises and the miner's fan hits its flow limit first.
