Cool, and i thought i was the only one fustrated and worried about temps in my comp.
OK if your looking for a program that covers almost everything you must get:
This program not only shows the temperature of your cpu, or if you have two cpu, it can show temperature of parts in your motherboard, harddrive and more. You can also see the fan speeds and even adjust them or overclock. Speedfan also has the capability to find voltages and you can play around with that too, but it is very not reccomennded. I LOVE this program and i use it in my desktop xp, and Speedfan has detected, almost everything, you can minimize it to the traybar and have it start from startup. If you wanna know how to ask me.
Next if Speedfan doesnt detect anything other than your cpus, (may be result to a motherboard doesnt like to be detected, or maybe an unsupported hardware.)
If thats the case, i use CoreTemp, i use it on my laptop, as SpeedFan can only detect the two cpus, so why install Speedfan, but have a much smaller utility CoreTemp.
So have fun deciding
