Why heat the processor?: Joule effect
I'll try to explain what is the effect of Joule , that happens to us every time we will increase our processor clock, vga, etc.
Joule effect is an effect of hot conductive material produced by the friction of the electrons with their mass (the driver). When electric current begins to flow through a processor, such is the speed the flow of electrons through its various transistors generate heat. That is why we noticed a rise in processor temperature when subjected to overclock and increases in voltage.
If a power driver circuits, part of the kinetic energy of the electrons is transformed into heat due to the collision who suffer with the molecules of the driver on the circuit, raising the temperature. This effect is known as Joule effect after its discoverer, the British physicist James Prescott Joule, who studied in the 1860's.
Joule effect can be expressed mathematically as:
Q = I ^ 2 * R · t
Where:
Q: heat energy generated
I: current intensity
R: electrical resistance of the conductive material
t: time Applications
Joule Effect:
Most of the time the joule effect is undesirable, for example, overclock, and that this phenomenon is necessary to use a suitable cooling system to keep the unit. Although it also has positive uses such as soldering irons, which operate by heating a metal part based on the joule effect, also the plates and a lot of devices that run "hot."
Now we know that heat processors normally do but also because when we raised the voltage and in this case is an undesired effect.
I hope they have been useful, Patagonian .
