Ebay Item I am using this on my Miners both side.
Amazon Item Using that on both side. One duct in the back of miner which will come all the way from my cold room (Might be you can use same way to your intake instead of cold room you can use either one vent of AC or directly from outside) and the front one goes to Heat room which is sealed and had 2 exhaust fan for air exhaust.
Thanks. One question, can I cut the Aluminum Foil Duct? or should I buy one for each side?
