<I>"Processor Heat Dissipation by Craig "CCW" Woolmer:-
Introduction:

Processors need to draw power to run. Just like any other machine, energy needs to be put into it for useful work to come out of it. This inevitably ends up as heat energy which is potentially lethal to a processor. Basically, the cooler a processor is, the longer it can be expected to last. Most of today's processors are designed to operate at a maximum temperature of 85°C (185°F.)

Even the processors are apparently able to handle this temperature; this is not the best temperature to run a processor at and will severely limit the processors life span. Unfortunately, due to the non-ideal nature of physics even the best machines have design flaws. With a microprocessor, it is that more energy than is needed for the work.

This energy excess energy is released in many ways such as sound, heat and radiation, Heat is almost always a bi-product of work. Heat is, as mentioned before lethal to a processor. When a processor gets too hot, the tiny transistors that make it work cease working.

A CPU requires energy input to output useful work. Power, is the amount of energy input for a length of time. This is generally measured in watts (W) or horse power (hp). For the duration of this article, watts will be used as they are better suited to measuring the power usage of a microprocessor.

Many modern processors require in excess of 50 watts to run at their stock (rated) speed. This is why at least a 300watt PSU is recommended for all Intel Pentium 4 and AMD Athlon systems. Every processor also requires a certain amount of voltage to be passed over it for it to work properly.

Electrical devices work because a flow of current passes from one point to another. Current flows from a high potential to a low potential zone. This is can also be called a voltage zone. This equation: Power = Voltage * Current (P = V * I) directly affects the amount of power the device is drawing."</I>

I hope you'll find it much better than the abysmal original.

Thanks to Daniel for putting it on the front page!
