This is our own design of the 8”Fan duct for Antminers double 120mm Fan.

I've also been told that these will fit on a Antminer L7 & S19 Pro, eBit 10.2, GoldShell LT5 Pro Goldshell CK6 & CK5 and Avalon 1166/1166 pro & 1246 as well.

Our design have our initials on them ALWAYS!

Made with premium material manufactured in the USA.

These take approx 6 hours to print, they are printed using standard setting, not high speed. they weigh approx 450g each.

Don't be fooled, not all 3D material is the same.

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.

If you want/need these printed in a different color or material, please message us for a quote. (this may add time to manufacture)

After Testing, we can not offer a 4" version, due to it limiting the air flow too much causing over heating on the miner. We do offer a 5" 6” version as well as a 7" version.

Design may vary slightly from photo, but changes will only be cosmetic!

Please Note that USPS charges are much higher than FedEx for larger quantity orders, will always offer a choice, but FedEx will always be much cheaper than USPS for any larger packages!
