Made with premium material manufactured in the USA.

This is our own updated design of the 6" Fan duct for Antminers 120mm Fan.

The fan ducts take approximately 2 hours to print and are printed using the standard setting, not high speed. Each fan duct weighs approximately 68 grams each.

Fan Ducts:

  • ·       Protect your miners from heat. The original destroyer of electronic. 
  • ·       Uses original screws. Easy fit, if you do purchase different screws, make sure to be careful of the length. Antminers have capacitors     behind some of the screw locations, if too long you can blow the hashboard.
  • ·       The fan ducts help reduce noise, and enable you to vent heat away from miners. 
  • ·       Its printed using PLA so no risk of fumes, like you can with ABS and heat.
  • ·       Printed in Black just to make life easy for all.
  • ·       Handling time may vary depending on how many we have printed and how many you order. We will try to ship same day if quantities allow.

Please Note - this listing is for the black adapter ONLY, this listing does not include anything else ( flexible ducting or hose clamp or iphone)

Before you purchase, please verify the heat requirements that you need.

The 3 materials I use are listed below with the temperatures the material will start to go soft (Glass Transition Temp)

PLA Pro (PLA +) - 54C = 130F

HIPS – 80C = 176F

Polycarbonate (PC) - 112C = 233F

I am not responsible for the material going soft above the GT Temp.

There are many reasons a miner can run hot, ducting, bends/kinks, length of the run, air pressure to name a couple.
