BITMAIN Antminer T9 S1 S3 S5 S7 S9 A3 D3 L3 V9 120mm High Temp Fan Duct 4 INCH USA made (1 PCS)

Worked for me with AC Infinity Flexible 4-Inch Aluminum Ducting. Used to route exhaust fan away from computer to keep it cooler. Wish the inside was black too.... Worked fine. Just seems a little over priced.But would buy again......

The media could not be loaded.  Most my fan shrouds dry up and crumble within a year and need to be replaced. They are done on home 3d printers. This product is not. It is PRO and will take a beating with the high heat (90+C) output of some miners. I also use them for adopting air intake filters that DO NOT put any stress on the fan and will double the life of your unit. They are also available on amazon. 4 inch car racing cone filters (dry).

Great product!! It just took to long to get to me!!

These fit a 120mm fan perfectly. Allows for easy adapting a computer fan to ductwork. Feels pretty durable. No complaints!
