HWMonitor (1.66) is a free hardware monitoring program for computers. It reads your system's sensors and displays real-time temperatures, fan speeds, and voltages. 
It is extremely useful for checking the “health” of the computer, preventing overheating, and identifying cooling problems.
Temperatures: In CPU (processor), GPU (graphics card), hard drives and motherboard.
Fan Speed (RPM): How fast your fans spin to adjust their performance.
Consumption & Trends: The Watts and Volts consumed by the main components.

You can download it directly from the official CPUID company website.
