Just look fan speed and temperature

, ambient temp is arround 22c , Very good resultat !!! and very low noise, the psu make more noise :p, by very low cost (free) just make 2 hole (arround 50-60mm)

Just for precision, on my "calculs' is very important do no make more larger of hole for assure to make air pressure at center hashboard at low speed fan, make hole at perfect center of miner at two side (look picture, so in absolute, juste turn the "in" fan).
For finish, VERY IMPORTANT, air flow for the two fan point external... so, air flow take on miner ant outake external ! the fan blade need place in interne... just see picture ! for assure, on power on, the air need to outake on 2 fan ! no admission, admission is NOW on two news hole !

And, VERY IMPORTANT to, you need TWO SAME fan !!! if not, the air flow is not correct, and is possible one part of hashboard is not in air flow, and overheat !
