    Pretty much all of them. It may be that there are some for embedded systems that use a single voltage, but anything for a PC will use several voltages.

    I SERIOUSLY doubt you have "opened the processor". More likely you have just opened the computer. The processor is the CPU chip and you can't "open" it without destroying it.

    Electrical components get hot and computers have particularly dense packing so there can be a lot of heat in a small space.

    The processor is lock based there are lot of pins

    Yes. So what is your point? What does "lock based" mean?
