Well as everyone knows the best way to cool something is to reduce the amount of heat that needs to be removed, right? Since electricity flowing through a wire generates a small amount of heat because of resistance in the wire, why not replace all the accessible wires in the case with larger gauge. E.g. go from 18 gauge to 14 or 12. If you're pushing the same amount of current through, its going to give you less vdrop and less resistance which = less heat to get rid of.

I've also heard of molex connectors *melting* which would indicate that the amount of heat generated by resistance is substantial.

Purchasing the wire needed to do this would probably cost a little more than just adding another fan, but wire doesn't make noise! (at least, not normally...)

Well, sounds good in theory, but I really don't think PC (well, mine anyhow) is creating much of its head due to wire resistance. the main reason is economics and space. How am I suppose to stuff heavier gauge wires behind my mobo tray for management?

CD in response to whether folding is a waste:

It would only be worthwhile to do it on high current wires (e.g. power to your graphics card), but I don't think you will see much (if any) difference. Grab the cables to your graphics card and see if they feel warm.

Most of the wires that this applys to are actually in the processors and other ICs.

It doesn't really matter how hot the wire that brings the electricity is, because if you up the voltage than you would get as much current as if the wire was colder. What's more important is cooling the actual mobo/gfx card where you can't up the voltage, so the voltage chips (I'm tired, forgot the name) are the main thing behind the Vcore.

edit: Although in the world of thousand-dollar gaming machines, doubling the price of each wire to have one about 2.5x the thickness isn't too bad.
