So i recently acquired an antminer s7 with bitmain's apw3-12-1600-b2 psu and immediately realised that it was loud. a bit too loud for my liking and i wanted to, somehow reduce the noise level, to make it bearable for me and the people around me.

I could possibly purchase 2 fans that'll have similar rpm, airflow, etc. I'm looking at the noctua nf-f12 pwm industrialppc-3000 as a candidate. another way is to build a noise-reducing cabinet (much like the one constructed by the one showcased in Fitzy's post here: https://bitcointalk.org/index.php?topic=1194785.msg13157846#msg13157846)

I'm no expert in the bitcoin mining community so help would be appreciated, thanks!

They are currently three contenders for high CFM / Static Pressure with acceptable noise level (around 40 dBA):
http://www.scythe-eu.com/en/products/fans/ultra-kaze-120.html @ 133 CFM
http://www.enermax.co.uk/fans/twisterstorm/ @ 154 CFM
http://www.silverstonetek.com/product.php?pid=711&area=en @ 173 CFM
The Noctua are just about 100 CFM and are not really powerful enough. I'll put the Grand Flex in the same category!
I'm running successfully overclocked S5 and slightly underclock SP20E with Twister Storm...
