I've run Speedfan on my laptop and desktop. The third temperature seems to indicate around 67 degrees with both machines, but doesn't say which device is which temperature. Everest (which I far prefer) shows all the sensors that it finds, says what they are, and what the temperature is.
My laptop CPU was getting up to 90 degrees C before I opened it up and put some thermpath between the CPU and heatsink. Now it's between 40 and 50 most of the time.
The desktop is stable at somewhere around 10 degrees hotter than the room for the CPU, and 5 degrees hotter for the HDD. I don't know what temperature the graphics processor is, because there seems not to be a sensor for that.
