BITMAIN Antminer 120mm High Temp Fan Duct 4 INCH USA Made — T9 S1 S3 S5 S7 S9 A3 D3 L3 V9 (6 PCS)

This listing is for BITMAIN Antminer T9 S1 S3 S5 S7 S9 A3 D3 L3 V9 120mm High Temp Fan Duct 4 INCH USA Made (6 PCS). Heavy-duty ducts designed to channel airflow from any standard 120mm fan, helping to lower noise and focus exhaust away from your mining setup. By improving ventilation, these ducts help maintain lower operating temperatures and extend the life of internal components — protecting your mining hardware and investment. Recommended configuration: attach a standard dryer hose, add a Duct Stat Fan Thermostat and a duct fan for controlled, efficient exhaust. If you run multiple Antminers, use a Y-connector to combine several ducts into a single vent. Installation is simple: secure each duct using the existing screws on your Antminer. Compatible with any standard 120MM fan for flexible, tool-free integration.
