Another dumb connector
graphics do coil whine now the motherboard will be a giant inductor... lol
The (any) MOBO is already a giant inductor. Well, technically it's an RCI (resistive-capacitive-inductive) circuit. All electronics are RCI circuits. Looking at it from the power supply's perspective, virtually all electric appliances and electronics are RCI circuits since there's a resistive component and a variable (based on load) power factor value. Inductive components don't _cause_ coil whine, they merely provide a means by which the combination of intra-circuit RCI loops which are pushing a lot of current and generating a lot of harmonics (because, simply put, there's no such thing as a square wave or saw tooth or triangle wave in the strict sense, they are the by products of harmonics [which are all sinusoidal] which are simply decaying multiples of the fundamental frequency). The inductor body (usually formed from ferromagnetic "dust" homogenized with some form of epoxy, to mold and bake the desired shape) act like the magnetic nub in the center of the cone of a speaker, the whine is a product of the ferrite body of the inductor resonating at it's natural (resonant) frequency, or very close to it, because when there's noise on the lines in the low end of the microwave spectrum there's a lot more harmonics arising from the fundamental, and the power throughput is so high, it's virtually unavoidable. All the inductors in all our computers have always resonated to some degree, it's just that the ampacity on a given line was never so high as it is now, what with 500 watt GPUs and 250 watt CPUs, and the voltage level being so low (<1.4V usually) Ohm's Law can't be negated. So a given line might only be 1.1 or so volts at 20, 30, 40 Amps over a short run.
But really, who the hell cares about coil whine, like, seriously? It's only an issue if it starts to warble, indicating an inconsistent power delivery line. With all he fans in the system, how can one even HEAR it over the cooling solution, Or are people sticking their heads inside their builds specifically to catch the coil whine, because I don't get it. Of course. unlike everyone else, my concern is function, not pretty things, so I have no panels on my system and I don't try to precisely control fan speeds. I use Noctua industrial PPC fans, and use very basic fan profiles. So they're already squelching out the noise by their own mean operational dB. Or maybe it's all the fans using PWM (pulse width management) these days to control their speed, and the sheer number of fans you need in a closed case to keep it cool with out having (oh em gee) too much fan noise in the background, because in my system I only use PWM for the radiator fans, and I run all the fans for a given rad off one header. The rest of the fans are set to DC max speed (12V) and don't ramp up and down because they're not very strong or very fast.
Finally, this whole "having to hide my cables" nonsense. Seriously. Are the PC cable management police going to hunt you down and fine you for "poor" cable management? IT'S A COMPUTER, IT'S A MEANS TO AN END, IT IS NOT AN ENDS IN ITSELF - WHO CARES ABOUT THIS CRAP? You buy or build a computer for it's function, whether it's to play video games or do some form of content creation or whatever. All that matters is it's performance and stability, not how pretty in pink it is. All these uselessly complicated builds with RGB and fifteen fans because god forbid you leave the cover off, and all these other gewgaws - are you using the PC, or are you watching it like a fish tank - seriously. I know in today's impolitely "polite" society I'm supposed to shrug and say some limp ism like "to each his own" or "whatever floats your boat". I happen to disagree with such wheedling absentee opines.
And yes, I am well aware everyone has a rectal sphincter. That doesn't invalidate my tightly argued oppositional proposition.
