I've got a bunch of pulled fans from S5 and S7 if you're looking for a stock replacement. If you're trying to make a miner quieter, good luck.
I have 1 Hashboard and 1 controller with 2 fans,
something has to be plugged in the fan sockets or it wont turn on
I have it in the lounge and its quite as a lamb
With an ordinary 500 watt power supply
blowing on the board
Its such a waste the fan on the supply goes nowhere so ive turned it on the hashboard
Its whats called open plan (there are no covers like a gpu miner)
Works a treat and decibels in the 40 and temp is 55
