Topic: Best exhaust fans for cooling 10kwh-15kwh (Read 501 times)

I have around  6 s4s and an asortment of Scrypt hardware A2s , Alcheminers and some Sp20s etc  In my basement

right now i am able to barely keep up with cooling requirements running the central Air constantly living room temp is around
85degerees so in the basement its closer to 90.

Asic temps waver between 40-60degerees.

I want to add more used hardware possibly anther 13k  watts and i will defintly need more cooling.   My problem is the basement is completely cement there is only a small gap between the poured basement and the surface no more than 10-15 inches so i could probbaly install a bunch of these :

13 inch  1000 cfm

13 inch 700cfm (i dont like this one since its a pull chain i don think it can be hooked up to a thermostat

it would require cutting into drywall above the basement and through siding to get the exhaust ports in so its a bit of a project.

on the other hand i have a sunken basement window that about 30 feet away from my servers , there are no obsurections since the basement is framed not finshed.  If i could install an industral type fan ( the windows is about  3 foot x 6foot)

i could probably mount something like this :

i noticed the wall cabinet type fans are more expensive that the wall panel type which type would i need to mount in a window ?

another issue is rain, when it rains water fills into the suken window chanel and sometimes flows into the room that could be really bad due to the motor getting exposed to water i imagine right ?

i really want a reversible fan like this but its quite expensive and a tad to big, but int the winter this would be aweomse for pulling cold air in.
