+
+Known Issues:
+ * The WMI implementation in some of Asus' BIOSes is buggy. This can result in
+   fans stopping, fans getting stuck at max speed, or temperature readouts
+   getting stuck. This is not an issue with the driver, but the BIOS. The Prime
+   X470 Pro seems particularly bad for this. The more frequently the WMI
+   interface is polled the greater the potential for this to happen. Until you
+   have subjected your computer to an extended soak test while polling the
+   sensors frequently, don't leave you computer unattended. Upgrading to new
+   BIOS version with method version greater than or equal to two should
+   rectify the issue.
+ * A few boards report 12v voltages to be ~10v.

+Kernel driver nzxt-smart2
+=========================
+
+Supported devices:
+
+- NZXT RGB & Fan controller
+- NZXT Smart Device v2
+
+Description
+-----------
+
+This driver implements monitoring and control of fans plugged into the device.
+Besides typical speed monitoring and PWM duty cycle control, voltage and current
+is reported for every fan.
+
+The device also has two connectors for RGB LEDs; support for them isn't
+implemented (mainly because there is no standardized sysfs interface).
+
+Also, the device has a noise sensor, but the sensor seems to be completely
+useless (and very imprecise), so support for it isn't implemented too.
+
+Usage Notes
+-----------
+
+The device should be autodetected, and the driver should load automatically.
+
+If fans are plugged in/unplugged while the system is powered on, the driver
+must be reloaded to detect configuration changes; otherwise, new fans can't
+be controlled (`pwm*` changes will be ignored). It is necessary because the
+device has a dedicated "detect fans" command, and currently, it is executed only
+during initialization. Speed, voltage, current monitoring will work even without
+reload. As an alternative to reloading the module, a userspace tool (like
+`liquidctl`_) can be used to run "detect fans" command through hidraw interface.
+
+The driver coexists with userspace tools that access the device through hidraw
+interface with no known issues.
+
+.. _liquidctl: https://github.com/liquidctl/liquidctl
+
+Sysfs entries
+-------------
+
+=======================	========================================================
+fan[1-3]_input		Fan speed monitoring (in rpm).
+curr[1-3]_input		Current supplied to the fan (in milliamperes).
+in[0-2]_input		Voltage supplied to the fan (in millivolts).
+pwm[1-3]		Controls fan speed: PWM duty cycle for PWM-controlled
+			fans, voltage for other fans. Voltage can be changed in
+			9-12 V range, but the value of the sysfs attribute is
+			always in 0-255 range (1 = 9V, 255 = 12V). Setting the
+			attribute to 0 turns off the fan completely.
+pwm[1-3]_enable		1 if the fan can be controlled by writing to the
+			corresponding pwm* attribute, 0 otherwise. The device
+			can control only the fans it detected itself, so the
+			attribute is read-only.
+pwm[1-3]_mode		Read-only, 1 for PWM-controlled fans, 0 for other fans
+			(or if no fan connected).
+update_interval		The interval at which all inputs are updated (in
+			milliseconds). The default is 1000ms. Minimum is 250ms.
