h3po / onSataHotplug.py

Last active July 7, 2016 16:07

I have a Sata Hotplug Bay with a rather loud fan hotwired to the back of it. To keep the noise down, I use a udev rule in combination with this python script to only turn on the fan while there is one or more disks attached to the controller card that services the ports.

	#!/usr/bin/python

	"""
	turn the fan to dc mode and off when the fan controller is initialized
	/etc/udev/rules.d/97-hwmon.rules:
	ACTION=="add", SUBSYSTEM=="hwmon", DRIVERS=="nct6775", ATTR{pwm5_mode}="0", ATTR{pwm5_enable}="1", ATTR{pwm5}="0"

	declare the disk as hotpluggable and run the script

My lm_sensors config for the Nuvoton NCT6793D on my Asus Z170-Deluxe Motherboard. Haven't figured out the voltages yet. To get the nct6775 driver working with the monitor chip, you need to boot with acpi_enforce_resources=lax to ignore the ACPI address space conflict with the EFI.
