I will buy 5000 m3 fan system to supply fresgh air for 10x the Antminer S9.
is it enough ?

I have read in multiple places on this forum that each S9 puts out about 250cfm of air. So if you got 10 of them you'll need to exhaust 2500 cfm of air. If your fan is 5000 cfm, then you should be good. I would consider two fans if I was you. 5000cfm for exhaust, and 5000 cfm for intake. At least that is the setup I am trying to go for.
I am using 4 of these fans. 2 for intake 2 for exhaust.

The fan in the link he gave is 5000m3/hr which is equal to 2942cfm not 5000cfm. With 10 S9 giving off 250cfm each.. he is still good with that fan.
Thanks for catching that. Its been a long day for me, I shouldn't be on here but was doing some light browsing before bed. Your correct he should be good with that fan.
