coil wine or coil noise is a phenomenon observed by the owners of All
Electronics in general but in particular graphics cards that can be freaking
annoying I mean I'm talking more annoying than this voice I'm doing right
now sorry electromagnetic coils can act as Transformers or inductors and in the
case of video cards the coils in question are acting as inductors meaning
that they are trying to resist changes in the electric current passing through
the making power delivery more stable these coils have a a resonance at which
they can actually physically vibrate or resonance frequency and since electronic
components are going to be receiving variable current a varying magnetic
field exists around the coil and when these magnetic forces affecting the coil
become strong enough which in the case of video cards usually occurs when it's
working harder it will cause that coil to vibrate and in some cases that
vibration can emit a high-pitched noise
like it can be especially noticeable in certain applications like games where
video card will be under varying amounts of load which will cause the card to
whine at a variety of different high pitches and can degrade your overall AAL
experience while using particularly open back headphones or speakers so the next
question I always get is okay so lus I understand what coil wine is oh how do I
fight it how do I get rid of it the unfortunate answer is that once you got
it it's kind of like ants you want ants
no you don't there's not a lot you can do to to get rid of coil wine in some
products damping or even doing things like applying silicone over top of the
offending component has shown a reduction in the amount of vibration and
therefore coil wine produced and some power supplies have been known to react
better or worse with different other components in the system to cause more
or less coil wine in either of those components but this is a very extreme
solution replacing your power supply every time that causes coil wine with a
particular component and the unfortunate thing here is that outside of very
extreme cases of coil wine most manufacturers will not fulfill an RMA
for an affected product and even if they did it's likely that it would be
considered normal for that product and the one that you get in return is going
to be the same anyway so in the case of computer hardware your only real defense
is to look into the products that you plan to purchase beforehand and make
sure that other users are not reporting coil wine issues certain individual
products are definitely affected worse than others in the case of graphics
cards it might be a particular manufacturer or a particular board
design that might be used across a variety of Manufacturers but you want to
watch out for which ones are getting good reports from people and which ones
are not then don't assume you're safe
just because you buy a you know a non- reference card from a good manufacturer
as with anything in life check those reviews online line before dropping a
bunch of your hard earn money on a product that may disappoint you down the line or buy from somewhere with a solid
return policy so if you do need to swap it up for something else you will be
able to one more tip though about coil line is make sure that you've nailed it
down to the right component often with
very high frequency noises it's difficult to locate exactly where
they're coming from so you might think that the coil line is being caused by
the PCB of your graphics card but maybe it's actually the fan above it that's
winding or the motherboard chipset below it or or whatever else you got to really
get your ears in there and figure out where it's coming from speaking of
figuring out where it's coming from I bet you guys didn't see this sponsor
spot coming from me today's episode
sponsor is Cooler Master they've got a wide range of reliable cases power
supplies air and liquid coolers like their neptun 240m which we actually
talked about a fair bit is great for keeping your CPU cool and they've also
got peripherals for gamers and enthusiasts alike for example their Nova
touch tkl that everyone keeps asking what is that keyboard in your video what
is that keyboard in your video you guys got to check out our ultimate keycap
replacement guide over on the lonus tech tips Channel because we cover that
particular keyboard why it's so special and how you replace all the keycaps on
it and make it look freaking awesome all the information about how you can use
their products most effectively and what each of them is meant to accomplished
can be found over at The Cooler Master website or at CMU Cooler Master
University they got a bunch of really great educational articles over there
and what's good about it is it's not just OMG by Cooler Master all the time
every day it's actually seeking to help you make a more educated purchasing
decision regardless of what you're shopping for so thanks to Cooler Master
for sponsoring this episode as fast as possible you guys for watching and like
this video if you liked it dislike it if you disliked it leave a comment if you have suggestions for future fastest
Possible episodes just like this one or different from this one whichever you prefer that's the point of suggestions
it doesn't have to be exactly the same thing I mean if everyone suggested I keep making the same video over and over
again I would keep making the same video over and over again and no one wants to see that thanks for watching bye
