Some of the sensors 23are only available via the EC. 24 25ASUS WMI interface provides a method (BREC) to read data from EC registers, 26which is utilized by this driver to publish those sensor readings to the 27HWMON system. The driver is aware of and reads the following sensors: 28 291. Chipset (PCH) temperature 302. CPU package temperature 313. Motherboard temperature 324. Readings from the T_Sensor header 335. VRM temperature 346. CPU_Opt fan RPM 357. Chipset fan RPM 368. Readings from the "Water flow meter" header (RPM) 379. Readings from the "Water In" and "Water Out" temperature headers 3810. CPU current
