I've got my active cooler plugged in it appears to be running at full speed all the time. My temps are ~35C. My understanding is that it shouldnt turn on until 50C. The fan state is set to 0 so it should be off.
I've read through a number of other posts on here and I'm convinced the fan is faulty with regards to the PWM wire. I can get the RPM so that means the other 3 wires work.
Any thoughts on next debug steps?

I can't even disable the fan with this command:cat /sys/class/hwmon/hwmon3/fan1_input
