Getting a couple S9's online, 14TH batch. Any way to adjust the fan speed and Clock anymore? cold basement and chips are 68-71. I'd like to turn fans down for noise and run chips around 88-92. I remember seeing a URL link to still access the fan and clock settings, latest shipped FW does not have those options anymore.
http://miner.ip.addr/cgi-bin/minerAdvanced.cgiThat's as good as it gets but not fan speed directly just a small amount of control over the max frequency
Well that sucks, I was able to run a quiet 2900-3200 RPM in the past, now these suckers stay at 4250. Don't know if I can take the humming
Issue solved, my son built me a arduino based modulator/controller that spoofs the fan speed to the miner at 90% and I can enter any fan speed I want. For me 45% is perfect, quiet and temps between 70-75. Actual RPM now is about 3600 and miner thinks its 90%. What a difference in noise. If anyone wants one of these fan speed modulators, please PM me. It spoofs the speed to the miner so it keeps hashing and allows you to enter any percentage you want to run, realtime edits. Watch your temps and keep dialing down the fan speed till you get he sound and temp to where you want them.
