-CPU (Tctl): This is the T_control temperature available on AMD CPUs only. On several generations before Zen (Ryzen), this is not a reliable representation of the temperature. On AMD Zen series this is the temperature used to control cooling and is a fixed offset from the real CPU temperature. Offset is used mostly on X-series and some Threadripper CPUs; in such case two values are shown: Tctl and Tdie. If no offset is used, then only a single value is shown as Tctl/Tdie, which equals the real temperature.
-CPU (Tdie): This value is shown in case the CPU uses an offset from Tctl and represents the real temperature (Tdie = Tctl - Tctl_offset).
-CPU Package: Shown on Intel CPUs represents a 256-millisecond average value (calculated by CPU) of the hottest temperature sensor within the CPU package.
-CPU Package (TSI): Available on pre-Zen AMD CPUs is the CPU temperature obtained via TSI interface.
