Raspberry Pi OS • Re: How can I retrieve fan speed ?

Hi

I've installed the light version of Raspberry Pi OS (0.4G image, no graphical UI) on my Raspberry Pi5. It in an argon one v3 nvme case.
I want to retrieve the current fan speed of the system.
I've read somewhere that you can get this value from /sys/devices/platform/cooling_fan/hwmon/hwmon2/fan1_input but I don't have this:

Code:

ls /sys/devices/platform                                     107c580000.hvs   axi        cam_dummy_reg  'Fixed MDIO bus.0'   phy     pwr_button     rp1_vdd_3v3     serial8250      timer 3fd165c0.nvram   cam0_reg   chosen          kgdboc              power   reg-dummy      sd_io_1v8_reg   snd-soc-dummy   uevent arm-pmu          cam1_reg   cpufreq-dt      leds                psci    regulatory.0   sd_vcc_reg      soc             wl_on_reg

Do I need to install some package to get this value ?
