Voltage and the Current draw at that Voltage and the ability to dissipate the heat.. You pretty much determine the voltage if you alter it from the BIOS determined value (Based on CPU)
So the varable is current. The current is based on several varaibles. (1) work down by the CPU based on what you + background programs are doing (Can Find % of CPU utilization. The freq used by the CPU ( stock vs OCed). Think of the CPU as a RCL circuit (RCL = Risistance, capacitance, inductive) When Freq goes up R - no effect, Xc (AC Resistance of a capacitor) goes Down, Xl (AC Resistance of an inductor) goes up. The bottom line here is that as Freq goes up the CPU Impeadeance (Fancy name for AC resistance) goes Down = Higher Current. The Temp also has an effect. IF Modern CPUs did not shut down above a given temp a condition called thermal runaway could occur. Semiconductors have a negative temp coeffient (As Temp goes Up R goes down). This means thas as the temp hits a given point the resistance goes down, so Current goes up causing MORE heat, R goes down more, I goes up more untill it goes POOF and gives that burning oder.
Power = Current x Voltag and Voltage = Current / Resistance

Intel CPU temperature
Intel have an inbuilt thermal protection system allowing the CPU to reach temp's above 100 and still be fine. But this does not mean you should allow this to go on for a long time.
Idle: 40 - 55 Load : 55 - 85
(intels are known for running hot so dont stress too much unless your close to 100 or so, you can setup alerts for when your CPU hits a certain temp)
AMD CPU temperatureIdle: 30 - 45 Load: 50 - 70 
Reasons CPU is overheating
It is not uncommon for a CPU to run hot and usually it is quite an easy fix the following are the most common reasons
1. Thermal Paste underneath your CPU has been applied poorly and not in a nice thing layer, if this is the case you can simply go out and buy some more , its very cheap and look for a thermal paste that comes with a brush to make applying it easier.
2. Your CPU needs a desperate clean and is clogged with dust , this is very common in old houses that get dusty easily, simply clean it out with a brush or can of compressed air. My secret method , cheap method is too use a simple manual foot pump for a swisse ball.... works great and cheaper than buying cans of compressed air.
3. You CPU cooling system has not been fitted properly or is generally poor, this being said the stock fan's that come with CPU's are usually adequate aslong as you aren't overclocking or doing anything extreme.
Signs of High Temperature on CPURunning your CPU constantly at a high temperature can be very damaging and may have the following implications
- Reduce the Life of your CPU
- Randomly Freezes or Resets your computer
- CPU totally burns out (this would take some time, at very high temps to occur, remember intel cpu temperature can get very hot especially prescott series)
Another great way to monitor your cpu temperature is to include desktop widgets to monitor your CPU temp at all times.
Let me know if you have any questions as I've played around with CPU temperatures a lot overclocked a few CPU's and have setup some watercooling too cool some of the hotter CPU's. goodluck :)
