Innosillicon T3+57T - PowerSupply

Context:

I try to replace the noisy fan on power supply, the fan using 4 wires: GND, 12v+, 5v PWM, RPM Signal.

I replace it with a Noctua 12v with 5v PWM, but it did not work.. And I put back the original fan, but the miner still do a error about psu Undecided

Problem:

Now I got error code 35 and power error code is 2048

Code:

    "err": {
      "err_code": "35",
      "err_msg": "0 2 1"
    },
    "power_vendor": "GP",
    "power_version": "1.70",
    "power_errorcode": "2048",

The error no 35/2048 refer to a stuck fan of powersupply.

Some one have already experiment with T3+

I also try to connect to the what is look like a serial port on microcontroller of PSU... but no signal

I also got log from the main api /stream/logs

If you have any idea let me know Cheesy

Update:

I found the problem with a signal analyzer, the proble come from the original fan, the RPM signal doesn't work anymore.
I bypass signal of RPM fan2 to the fan1, and now everything work!
