The voltage affects the temperature... more volts = higher temps
As for the "detail" bit what processor are you asking about?

Ummm, very basically...
As you increase the frequency of a processor, the processor works harder obviously. In order to power this increase in processing power, more voltage is required through the processor. So you up the cpu voltage slightly so it can cope.
This increase in voltage and increase in frequency of the chip makes the processor run hotter.
If the up the voltage too much, the transistors inside the processor cannot cope and they can blow causing the chip to die.
If you do not have sufficient cooling, then at around 95 degrees with intel i think the chip realises there is a problem and so shuts itself down to prevent overheating. If the chip does overheat the any solder points, along with micro transistors inside the chip can melt, again causing the chip to die.
You dont really need to know more detail than that, just know if you increase the clocks of the cpu, you need to increase the voltages to keep it stable, and doing this will raise temperature.
Every processor is different however due to 'silicone lottery' and so each will have a different thermal threshold and may require a higher voltage than others in order to get to the required clock speed the user requires.

Rub your hand against a coarse piece of fabric. As you increase the speed the heat you feel on your hand shall increase. That's how I interpret it, anyway. When you increase the voltages you're increasing the energy of the electrons passing through the chip and thus their speed. There's friction between your hand and the fabric as there is between the electrons and the silicone.
If this is completely wrong, i'm going to feel a fool...but I think that's right.

welcome to the forum,
as explained in above posts another to concider..
when intel had sandy bridge (32nm architecture) overclocking with
1.425-1.5v gave us some 72°-85° temperatures on air-cooling.
now intel hands us ivy bridge (22nm architecture) and the same
overclocking voltages yield a lot warmer temperatures. the smaller
components get the more concentrated the heat value can get with
the same voltages. thermal effieciency, varibles that promote heat
and thermal transfer are the major concerns for CPU voltage with
temperature control.
