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