Can anyone tell the average Cubic Feet per Hour of an ASIC miner please?

I expect to receive my first larger asic miner soon. In order to not mess up with my neighbors because of the strong noise in residential area, I plan to place it in the center of an auxillari building.
My plan is to create an air duct between the ceiling joists and to press some fresh air from the north side roof overhang, and let it flow through the miner out on the south side roof overhang.
Because of the limited available power in that building I will be able to put 3 to max. 6 large miners.

I have for free a HVAC Duct fan that moves 19400 cubiq feet per hour.

Can anyone please tell me if this amount of air movement is enough for 3 to 6 large asic miner?

The average Asics fan pushes 200cfm per fan so that’s 12,000cfh per fan. So no the air duct does not have enough volume of air.

I have one of these, https://www.amazon.com/dp/B07J64TCBQ?ref=ppx_yo2_dt_b_product_details&th=1, and measured 1730 cfm on the hot side of my LT5 Pro.

My LT5’s two exit fans neck down to a single 6" duct (2:1 fan shroud available on eBay) so it should be a fair representation of air flow - assuming the instrument is properly calibrated.

thank you both for your feedback.
at least I know that I need to look out to organize a much larger fan.

Look up your noise ordinance. Mine is 65 db at property line. The 11 machines in the garage make 45 db at the line. The neighbor might not like it, but nothing he can do

…well, that is different here!
