Why do CPU's get hot ?

NM I think I got what I was looking for....

Why do CPU's get hot ?

Man I was scratching my ass all night thinking about this too. Im still scratching!

[STEvil]

something about resistance and capacitance of a circuit..

[Allubz]

They don't, it's a sensor bug.

lol this is the best thread in xtreme overclocking ever

[Tomasis]

it gest hot because it is sexy

[sin0822]

because they can

basically, the objects you are forcing electrons through are not perfectly smooth on the atomic scale so the electrons take a weird route and deposit some energy into the object because they have to change direction and speed
( this is partly the reason some electronics can be improved with more conductive materials, such as gold, silver )

if you want it really simple it gets hot from friction, essentially

now, what i think you really mean is why is my cpu hot, and that's probably because the heat-sink is dusty or the voltage is too high

CPU's get hot because reasons.

[massman]

if your cpu gets hot, you're doing it wrong

[kikicoco1334]

because there is electron flying though the dies and because it's speed and that creates fraction and that creates heat cuz it's energy needs to be released

[NKrader]

how do magnets work?

Come on everyone / this person's asking a serious questions that deserves an honest answer... Most newer CPU's get hot because they have plutonium circuits which require allot of voltage... This causes allot of heat which requires extra cooling...

Intel Core i7 2600K @ 5.0 GHZ

you should lower CPU frequency and voltage if it's getting hot

^^this.

the movement of electrons causes friction, hence the heat.

CPUs get hot so Paris Hilton has a purpose

[bmaverick]

The same reason why a wood chuck chucks wood and gets hot chucking all day long. If you were a wood chuck you would know why CPUs get hot too.

[Nikolasz]

Cpu are allways hot, some are well cooled and then are warm...

Cpu as for many years are known as cpu, but latley i can call cpu Spu=support processor unit.
Nowdas we got even "audio processing" inside graphics processors=gpu that can take extreme calculations away from Cpu.

You do realize that space between atoms is thousands times greater than size of electron right ?
There is no friction on that scale.

Agree, i dont create chips and cpus, i just use them

I guess here: http://www.allaboutcircuits.com/vol_1/chpt_2/5.html

In lamens terms the resisters required to produce the 0/1 series of instructions @ a transistor level have to have resisters up to them to deliver the power required to each one. Adding resistance to control the power flow to precise levels generates heat in addition to when the actual circuit switches for its clock speed. When the flow of power is cut off the excess has to go somewhere either in terms of heat, light or magnetism same with the other power that was wasted to get your previous 1.25v down from your AC power source or DC power source ie 12v. The higher the power power a chip needs the higher the flow has to be and the higher the flow the more power that is wasted getting it down it and the wasted power is turned into heat.
