<p>[QUOTE="fatima, post: 1433033, member: 22143"]The heat isn't generated by the + & - DC power pins on the chip. The heat is generated within the chip when transistors are switched. During this transition you get a instantaneous short between positive & negative. On paper this means infinite current for a very short amount of time. In reality their is some resistance which prevents it but this is where the heat comes from. It's infinitesimally small, but in a chip with millions of transistors being operated at the gigahertz range the heat rises fast. Look inside your computer. The heatsinks are mounted right on the processing and graphics processor chips because this is where all the switching takes place. The rest of the computer is relatively cool in comparison. As I mentioned above, the switching takes place on silicon based semiconductors. There is no place where silver would benefit this. </p><p><br /></p><p>In regards to the wiring in the circuit board, which is almost 100% copper, DC resistance isn't the issue. The address bus, data bus, control lines, etc are all moving at very high frequencies. This is where impedance & capacitance are important and that has more to do with the shape and position of the circuit wiring relative to each other and ground planes. The properties of copper are well understood in this realm and until a different technology comes along it won't be replaced. </p><p><br /></p><p>I am a bit rusty with it, but over the last 20 years, computers chips have been speed up by making the circuits smaller and thus they can be placed closer together. The other places where a moderate amount of heat are generated inside a computer are with the power supply. You could build a silver power supply but why? It would be like using silver cables for car wiring and it wouldn't prevent the heat. And heat is generated by the hard drives mostly due to the heat of the motors.[/QUOTE]</p><p><br /></p>
