Hello,

Just recently purchased a used S9, 1 board not hashing. I had the previous owner reboot the device and saw it come back to hashing on 2 cards. He had it hooked up with an APW3++ to 220v. I brought it home, hooked it up to the APW3++ on 110v, but left the non hashing card unhooked (knowing the power limitations of the APW3++ on 110v). Here's what happened:

1. I let it sit for over an hour. No hashing. Checked the kernel log, recognized both boards, but started cycling through checking the fans and said "Fatal error: fan speed too low"
2. Unhooked I/O cable for 2 boards, leaving board #1 connected. Boots up, starts hashing within 5 minutes.
3. Disconnected board #1 and connected #2, started hashing with 5 minutes.
4. Hooked both boards back up, kernel log shows fan error.

Any ideas?

Flash the device with different firmware? Try a different fan port on the controller?

Stop buying industrial miners, running them at home, and then complaining about the noise.

No, only 1 fan is working. The one reading 720 is only spinning because of the other fan forcing air through it. Usually it is the exhaust fan that dies.

You are right, but it is not always the exhaust fan that dies. In my high corrosion area the intake fan fails maybe 4 out of 5 times.

The higher numbered fan sockets are closer to the edge of the controller board. Just follow the wire from the socket to find out which fan you need to replace. (So in your case, fan[3] is lower and its socket is farther from the edge of the board).

Ignore scammers on Skype, Telegram, etc. I will only ever contact you via forum PMs. See profile for fingerprint.
