I've build a small miniITX system with Pentium 4 processor. It works fine but there's extremely hot temperature is shown by the CPU sensor, around 120 C. Of course this is causing the fan run extremely fast as well making the whole system very loud. I tried to touch the CPU radiator but it is very cool so this should be some kind of error. Could you please give me an advice on how to troubleshoot this?

If the CPU heatsink is "very cool" you may not have good physical contact between it and the CPU. Only way to troubleshoot this particular case is to remove remove/reapply the thermal paste between the two and hope it improves the situation. I would try updating the BIOS first as per Sadface's suggestion.

Have you tried updating your BIOS? In some cases, this fixes sensor readings (or corrupts them, as it did for me once :)

Also you could try verifying that reading with different applications - CoreTemp showed accurate readings for me.
