this does not belong here it belongs in alt coins as it is for the l3
the l3 uses way less power then the s-9
this idea will not work for the s-9 you will burn the gear up
unless you put the s-9 on old firmware and clock it to use 800 watts

Dimensions 350mm(L) x 135mm(W) x 158mm(H)
Cooling 2x 12038 fans; Front fan: 6000rpm, Rear fan: 4300rpm
Operating Temperature 0°C to 40°C
Network Connection Ethernet
Frequency Automatically set 1372 x 1.1 = 1509 watts for the 14th s-9
1323 x 1.1 = 1455 watts for the 13.5th s-9
1274 x 1.1 = 1401 watts for yje 13 th s-9
all auto set fans and hash rate so your idea does not work for them
the ducts are way too small ,
this works
https://bitcointalk.org/index.php?topic=2245487.0but will drop the s-9 to around 67 db due to auto settings
