Three sensors are available: fan speed, pump 20speed and coolant temperature. 21 22Fan and pump control, while supported by the firmware, are not currently 23exposed. The addressable RGB LEDs, present in the integrated CPU water block 24and pump head, are not supported either. But both features can be found in 25existing user-space tools (e.g. `liquidctl`_). 26 27.. _liquidctl: https://github.com/liquidctl/liquidctl 28 29Usage Notes 30----------- 31 32As these are USB HIDs, the driver can be loaded automatically by the kernel and 33supports hot swapping. 34 35Sysfs entries 36------------- 37 38======================= ======================================================== 39fan1_input Fan speed (in rpm) 40fan2_input Pump speed (in rpm) 41temp1_input Coolant temperature (in millidegrees Celsius) 42======================= ========================================================
