Reaaltemp Ti also gives you operating frequency, clock, multiplier and load, VID or CPU power or time, c-state statistics, and can alarm on temperature. It is more compact than hwinfo64 and can be started minimized displaying max core temperature in the system tray. HWinfo64 can do all of this except for the processor c-state statistics. Hwinfo64 can also display time series graphs for any of the items it monitors, including disk and gpu values. I use both depending on my needs, realtemp being more lightweight.
