`hddfancontrol -d /dev/sda /dev/sdb -p /sys/class/hwmon/hwmon1/device/pwm2 /sys/class/hwmon/hwmon1/device/pwm3 --pwm-start-value 200 200 --pwm-stop-value 75 75 --min-fan-speed-prct 10 -i 60 --spin-down-time 7200 -b -l /var/log/hddfancontrol.log`
## Systemd service
A systemd service file is provided to control the daemon easily.
If you installed hddfancontrol from a distribution package, you likely already have it installed, otherwise you can install it from the sources of this repository with:
```
sudo cp ./systemd/hddfancontrol.service /usr/lib/systemd/
sudo mkdir -p /etc/conf.d
sudo cp hddfancontrol.conf /etc/conf.d/hddfancontrol
```
Then you need to edit the `HDDFANCONTROL_ARGS` variable in `/etc/conf.d/hddfancontrol` to set the parameters (drives, temperature range...).
You can then start the daemon with `sudo systemctl start hddfancontrol`, see its status with `sudo systemctl status hddfancontrol` and enable automatic startup at boot time with `sudo systemctl enable hddfancontrol`.

# HDD fan control daemon startup arguments
# -d DRIVE_FILEPATHS [DRIVE_FILEPATHS ...], --drives DRIVE_FILEPATHS [DRIVE_FILEPATHS ...]
# Drive(s) to get temperature from (ie. /dev/sdX)
# (default: None)
# -p FAN_PWM_FILEPATH [FAN_PWM_FILEPATH ...], --pwm FAN_PWM_FILEPATH [FAN_PWM_FILEPATH ...]
# PWM filepath(s) to control fan speed (under /sys)
# (default: None)
# --pwm-start-value FAN_START_VALUE [FAN_START_VALUE ...]
# PWM value (0-255), at which the fan starts moving. Use
# the -t parameter, or run pwmconfig to find this value.
# (default: None)
# --pwm-stop-value FAN_STOP_VALUE [FAN_STOP_VALUE ...]
# PWM value (0-255), at which the fan stop moving. Use
# the -t parameter, or run pwmconfig to find this value.
# Often 20-40 lower than start speed. (default: None)
# --min-temp MIN_TEMP Temperature in Celcius at which the fan(s) will be set
# to minimum speed. (default: 30)
# --max-temp MAX_TEMP Temperature in Celcius at which the fan(s) will be set
# to maximum speed. (default: 50)
# --min-fan-speed-prct MIN_FAN_SPEED_PRCT
# Minimum percentage of full fan speed to set the fan
# to. Never set to 0 unless you have other fans to cool
# down your system, or a case specially designed for
# passive cooling. (default: 20)
# -i INTERVAL_S, --interval INTERVAL_S
# Interval in seconds to check temperature and adjust
# fan speed. (default: 60)
# --spin-down-time SPIN_DOWN_TIME_S
# Interval in seconds after which inactive drives will
# be put to standby state. (default: None)
# -v {warning,normal,debug}, --verbosity {warning,normal,debug}
# Level of logging output (default: normal)
# -l LOG_FILEPATH, --log-file LOG_FILEPATH
# Filepath for log output when using daemon mode, if
# omitted, logging goes to syslog. (default: None)
# --hddtemp-daemon Get drive temperature from hddtemp daemon instead of
# spawning a new process each time temperature is probed
# (default: False)
# --hddtemp-daemon-port HDDTEMP_DAEMON_PORT
# hddtemp daemon port if option --hddtemp-daemon is used
# (default: 7634)
#
# HDD fan control daemon startup arguments, for use as a systemd service
# This file should be located at /etc/conf.d/hddfancontrol
#
# Run 'hddfancontrol -h' to see help about all available arguments.
# Note that the parameters -b/--background, -l/--log-file and --pid-file should not be used here, as systemd handles both daemonization of the process and logging.
