I'm not sure about this and if it is possible. I need to read CPU (normal computer) into an Arduino. This could be possinble (at least I think) by connect some kind of sensor that can be placed between heatsink and cpu, where the thermal paste is placed. Or, second option is to read values from the system somehow, or from the motherboard. I hope I'm not talking about stupid things. I need some advices about this.
