Hello,
I know that I've away for a while, but I dont want anyone to burn their miners :-)
I still think that it is a good idea and there are Fans less expensive, ~20€ with the same CFM that solve the noise fan problem forgetting all the boxs and all the others things.
But beware with high CFM... I tried with 400 CFM, and when I turn on the fan with the miner off, the FRONT fan started moving quickly... When I turned on my miner, after some minutes it went off... I still think that is a good idea, but if the REAR FAN (inline 20€) as a big higher CFM, the front Fan will burn or will burn the board
... Dont make the same mistake that I did...
if someone buy one of these inline fans, it will solve the noise problem with 20€, but choose one with the CFM closest to miner REAR FAN CFM as possible :-)
