3D Printed Fan Shroud for Bitmain Antminers that use 120mm fan including AntMiner S1 S3 S5 S7 S9 L3+ D3 A4.
Fan shroud is used to attached a 6 inch duct to exhaust air. This item is for only the fan shroud. The picture of the Antminer is for demonstration purposes only.
This shroud decreased our Antminer S9 temps by 10 degrees compared to when we were using a 4″ duct.
Printed in PLA. We’ve tested this on an Antminer S9 for days and there is no signs of warping.
Requires longer screws that can be purchased at Home Depot. The exact size you need is #8-32 x 1-3/4 Inch
DO NOT use longer screws other than the ones specified or you may damage the boards, specifically the top left screw… if a longer one is used there is the possibility of the screw damaging a capacitor on the board.
