Not really a sharer, but why not.
Removed the fans from a S9 and tested it with an inline duct fan, with reduced speed.
It is very very tolerable, i could say silent but not bedroom silent, definitely kitchen/TV room plausible!
Miner is underclocked at 8.6V/550mhz/1000W
http://prntscr.com/1s6mphwreminds mo of my portable AC, when the fan (plastic) breaks (the one that vents the compressor and condenser heat). i can't find the replacement fan so i used a duct fan to suck the hot air from the exhaust.
BTW it is a 2hp aircon getting cooled.
duct fans are
quieter than the vent fans and are pretty durable(bearing type).
just make sure to make routine/preventive maintenance on capacitors after 2-3years, they are the first one to go..always have spares.
