Hey all,
I have been mining bitcoin for some time, and as such I am the owner of a few Antminer rigs. However, I had some issues keeping the miners cool in the tight space that my wife said I could keep them. This led to poor efficiency and very loud miners (not good).
I wanted to share my Antminer fan ducts that hook up to standard 4" and 5" hoses and have been excellent at keeping the miners cool and noise levels down. They are designed to use the existing hardware and just attach to the miner. They are 3D printed using ABS plastic, so they are durable and strong They can be used on the intake and exhaust fans. Here are some pics:
