CPU-Z is a great application, but it doesnt show the temperature of a CPU. GPU-Z is also a great application, but it doesnt show the temperature of the GPU. Core-Temp will show the temperatures of each computer core, but not much else.

So, the creators of CPU-Z have just released a new application called CPU-ID Hardware Monitor which seems to fill the holes that the above programs missed. CPU-ID Hardware Monitor is a stand alone, freeware utility which shows the voltages of the system on each rail, the system temperature (in total and on each core), the fan speeds and the temperature of the GPU. It will even show you the temperatures of each hard drive.
