Peck. What psu are you using? Have you tried a different one?
I am using the bitmain power supply... 220 V
But the power supply on that particular S9 machine is not the new apW3++
SO I will swap power supplys and see if that helps .. Thanks for the idea!
I just have a hard time believing it is getting to hot... I have miners ranging all over the place from mids 70's to pushing 100 (all in the same exact location)
Does not seem to make any difference to them... lots of people on bitcoin say they run them up to 100 degrees with no problem..(I'd prefer they not be at that but it cant be the room temperature if some are completely cool and some running that much hotter?
Maybe it is something to do with that 13.5 batch?
Running out of ideas... I am running some cooler air back there now but does not seem to change much...
But that machine would stop hashing before, now it keeps running, just those fans revving up and down...
Not sure what is going on with that fan speed reading..my guess it it a faulty reading...
Thanks for all the help! Will let you know what I find out...
Is it possible to go back on the S9 firmaware to the older versions where I can control fan speed and freq?
Again thanks to all!!

Switch the PDU/PSU, see if it follows it or stays with that particular s9. I have three of them and one runs a little hotter and "faster" than the other two, no matter which PDU/PSU or 110/220 I try. They're not all built the same.
