- Description:
- ------------
- ASUS mainboards publish hardware monitoring information via WMI interface.
- ASUS WMI interface provides a methods to get list of sensors and values of
- such, which is utilized by this driver to publish those sensor readings to the
- HWMON system.
- The driver is aware of and reads the following sensors:
- * CPU Core Voltage,
- * CPU SOC Voltage,
- * DRAM Voltage,
- * VDDP Voltage,
- * 1.8V PLL Voltage,
- * +12V Voltage,
- * +5V Voltage,
- * 3VSB Voltage,
- * VBAT Voltage,
- * AVCC3 Voltage,
- * SB 1.05V Voltage,
- * CPU Core Voltage,
- * CPU SOC Voltage,
- * DRAM Voltage,
- * CPU Fan RPM,
- * Chassis Fan 1 RPM,
- * Chassis Fan 2 RPM,
- * Chassis Fan 3 RPM,
- * HAMP Fan RPM,
- * Water Pump RPM,
- * CPU OPT RPM,
- * Water Flow RPM,
- * AIO Pump RPM,
- * CPU Temperature,
- * CPU Socket Temperature,
- * Motherboard Temperature,
- * Chipset Temperature,
- * Tsensor 1 Temperature,
- * CPU VRM Temperature,
- * Water In,
- * Water Out,
- * CPU VRM Output Current.
- 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.
