Available sensors are pump, internal and external17(controller) fan speed in RPM, their duties in PWM, as well as coolant temperature.18 19Attaching external fans to the controller is optional and allows them to be20controlled from the device. If not connected, the fan-related sensors will21report zeroes. The controller is a separate hardware unit that comes bundled22with the AIO and connects to it to allow fan control.23 24The addressable LCD screen is not supported in this driver and should25be controlled through userspace tools.26 27Usage notes28-----------29 30As these are USB HIDs, the driver can be loaded automatically by the kernel and31supports hot swapping.32 33Sysfs entries34-------------35 36=========== =============================================37fan1_input Pump speed (in rpm)38fan2_input Internal fan speed (in rpm)39fan3_input External (controller) fan 1 speed (in rpm)40fan4_input External (controller) fan 2 speed (in rpm)41fan5_input External (controller) fan 3 speed (in rpm)42fan6_input External (controller) fan 4 speed (in rpm)43temp1_input Coolant temperature (in millidegrees Celsius)44pwm1 Pump duty45pwm2 Internal fan duty46pwm3 External (controller) fan duty47=========== =============================================48
