BITMAIN Antminer T9 S1 S3 S5 S7 S9 A3 D3 L3 V9 120mm High Temp Fan Duct 4 INCH USA Made (20 PCS)

Pack of (20 PCS) high-temperature fan ducts made in the USA for BITMAIN Antminer models T9, S1, S3, S5, S7, S9, A3, D3, L3 and V9. These 4 INCH ducts fit any standard 120mm fan and help reduce noise while keeping your Antminer running cooler — which extends component life and protects your revenue-generating hardware. Installation is simple: use the existing screws on your Antminer to mount the duct. For improved airflow control, connect a standard dryer hose, a Duct Stat Fan Thermostat and a duct fan. If you operate multiple Antminers, add a Y-connector to combine several ducts into one line. Compatible with any standard 120MM Fan.
