HWMonitor is a freeware hardware monitoring program from CPUID for the PC that reads the voltage, temperature, and fan speed (displayed as RPM). The program can handle most common sensor chips, can read modern CPU’s on-die core thermal sensors, hard drive S.M.A.R.T, and the video card’s GPU temperature. The picture below is an example of the CPUID HWMonitor screen and output. The current value, and the recorded minimum and maximum values, are listed in the chart.
