Anyway, a sensor that is enabled may actually be not53connected and thus provide zero readings.54 55 56Limitations57-----------58 59The following features are not supported in current version:60 61 - SmartFan control62 - Watchdog63 - GPIO64 - external temperature sensors65 - SMI66 - min/max values67 - many other...68
