Weird Fan Problem on RNDP6000 with 6.4.0
Hello,
When I have my stock 120mm rear fan (or aftermarket) plugged in, it will spin fast at boot up, but it will not spin after that.
I thought the fan was bad, so I purchased a Noctua replacement, which did the same thing. The fan spins at bootup, then once booted no more.
I saw a thread about a CPU fan and there is a BIn file called ToggleSwitchProFan_1.0-x86.bin, but I have not used that yet. The fan is plugged in correctly to the stock connector. I even tried the other unused connector on the daughtercard, that does not work either. Either 120mm fan will spin fine when using any other power supply.
While I just noticed this recently, I am not sure how long it has been happening. I did a complete factory reset when I went from 4.x to 6.4.0. I am not sure if this existed before or after the upgrade.

Thanks for the help.

I fixed it, this is the post that tells you what to do:
Add the following line to the system.conf file (I added to the end of the file& beginning) in the /etc/sensors.d folder:
ignore fan3
I actualled added both ignore 2 & 3, not sure which did the trick. There is also a file called pro6-fan.conf, so I added there as well.
Here is my entire system.conf file:
root@RNDP6000:/etc/sensors.d# more system.conf
chip "coretemp-isa-0000"
label temp2 "CPU"
ignore temp3
ignore fan3chip "w83627dhg-isa-*"
