Title: Loudness of S9
Post by: Shane2821 on October 04, 2016, 11:02:47 AM
The s9 is an extremely loud miner. What can one do to make it more quiet? 70+db :(

Underclock it and turn the fans down to a manual percentage. Acoustic ducting either end to deaden the sound. I saw a video that one guy changed the exhaust fan to a corsair or something as the original fans ran at slightly different speeds and was causing some kind of resonance in the miner.

Don't change the fans  the gear needs air.

 downclock from  600 to  400 lower fans

or downclock from 550 to 350 lower fans.




you could buy this  and down clock less

 set it up like this

inserting units inside the duct may reduce the acoustic side, however, probably increase the dead unit risk as S9 is just like any other electronics.  You have to consider ESD effect and little jolts from dry air season.  DUCT does reduce noise that is for sure tho but please prepare for some hash PCB loss or control module loss in a longer term. 

S9 fan speed is manually changeable, however, if you do not have heavily air conditioned room, please be very careful with manually adjusting the fan speed.  Fan speed adjustment can bring you 2 possible benefits that is Noise and Electricity Consumption.  There is a con to that of possibly damaging the S9 if something goes wrong.  If you are in USA/Russia/Ukraine, repair is locally available to you, however, its not free. 

If the noise is the problem R4 is the way to go

Try underclocking the S9 and see if it helps...

good points  the s7  was able to do this, but  due to the smaller chip size  the s9  is a bit more delicate then the s7.

If you go the route of ducting an s9 it could damage due to static charge.

the line of the duct is static resistant temp plastic the center is fiberglass also static charge resistant,
but  the outside of the duct is aluminum so  if you ground the outside it would be less likely to spark static electrical discharges.

I have used ducting with s7's  pretty much perfectly for all of last winter.  Yet to do it with an s9
