coil wine or coil noise is a phenomenon observed by the owners of All
0:04
Electronics in general but in particular graphics cards that can be freaking
0:08
annoying I mean I'm talking more annoying than this voice I'm doing right
0:12
now sorry electromagnetic coils can act as Transformers or inductors and in the
0:16
case of video cards the coils in question are acting as inductors meaning
0:21
that they are trying to resist changes in the electric current passing through
0:25
the making power delivery more stable these coils have a a resonance at which
0:31
they can actually physically vibrate or resonance frequency and since electronic
0:35
components are going to be receiving variable current a varying magnetic
0:39
field exists around the coil and when these magnetic forces affecting the coil
0:43
become strong enough which in the case of video cards usually occurs when it's
0:47
working harder it will cause that coil to vibrate and in some cases that
0:51
vibration can emit a high-pitched noise
0:54
like it can be especially noticeable in certain applications like games where
1:00
video card will be under varying amounts of load which will cause the card to
1:04
whine at a variety of different high pitches and can degrade your overall AAL
1:10
experience while using particularly open back headphones or speakers so the next
1:16
question I always get is okay so lus I understand what coil wine is oh how do I
1:20
fight it how do I get rid of it the unfortunate answer is that once you got
1:24
it it's kind of like ants you want ants
1:27
no you don't there's not a lot you can do to to get rid of coil wine in some
1:31
products damping or even doing things like applying silicone over top of the
1:37
offending component has shown a reduction in the amount of vibration and
1:41
therefore coil wine produced and some power supplies have been known to react
1:46
better or worse with different other components in the system to cause more
1:51
or less coil wine in either of those components but this is a very extreme
1:57
solution replacing your power supply every time that causes coil wine with a
2:01
particular component and the unfortunate thing here is that outside of very
2:06
extreme cases of coil wine most manufacturers will not fulfill an RMA
2:11
for an affected product and even if they did it's likely that it would be
2:15
considered normal for that product and the one that you get in return is going
2:19
to be the same anyway so in the case of computer hardware your only real defense
2:24
is to look into the products that you plan to purchase beforehand and make
2:28
sure that other users are not reporting coil wine issues certain individual
2:33
products are definitely affected worse than others in the case of graphics
2:38
cards it might be a particular manufacturer or a particular board
2:42
design that might be used across a variety of Manufacturers but you want to
2:46
watch out for which ones are getting good reports from people and which ones
2:50
are not then don't assume you're safe
2:53
just because you buy a you know a non- reference card from a good manufacturer
2:57
as with anything in life check those reviews online line before dropping a
3:00
bunch of your hard earn money on a product that may disappoint you down the line or buy from somewhere with a solid
3:05
return policy so if you do need to swap it up for something else you will be
3:09
able to one more tip though about coil line is make sure that you've nailed it
3:14
down to the right component often with
3:17
very high frequency noises it's difficult to locate exactly where
3:21
they're coming from so you might think that the coil line is being caused by
3:25
the PCB of your graphics card but maybe it's actually the fan above it that's
3:29
winding or the motherboard chipset below it or or whatever else you got to really
3:33
get your ears in there and figure out where it's coming from speaking of
3:37
figuring out where it's coming from I bet you guys didn't see this sponsor
3:40
spot coming from me today's episode
3:44
sponsor is Cooler Master they've got a wide range of reliable cases power
3:49
supplies air and liquid coolers like their neptun 240m which we actually
3:53
talked about a fair bit is great for keeping your CPU cool and they've also
3:56
got peripherals for gamers and enthusiasts alike for example their Nova
4:01
touch tkl that everyone keeps asking what is that keyboard in your video what
4:05
is that keyboard in your video you guys got to check out our ultimate keycap
4:08
replacement guide over on the lonus tech tips Channel because we cover that
4:12
particular keyboard why it's so special and how you replace all the keycaps on
4:16
it and make it look freaking awesome all the information about how you can use
4:20
their products most effectively and what each of them is meant to accomplished
4:24
can be found over at The Cooler Master website or at CMU Cooler Master
4:28
University they got a bunch of really great educational articles over there
4:31
and what's good about it is it's not just OMG by Cooler Master all the time
4:36
every day it's actually seeking to help you make a more educated purchasing
4:40
decision regardless of what you're shopping for so thanks to Cooler Master
4:44
for sponsoring this episode as fast as possible you guys for watching and like
4:47
this video if you liked it dislike it if you disliked it leave a comment if you have suggestions for future fastest
4:50
Possible episodes just like this one or different from this one whichever you prefer that's the point of suggestions
4:54
it doesn't have to be exactly the same thing I mean if everyone suggested I keep making the same video over and over
4:58
again I would keep making the same video over and over again and no one wants to see that thanks for watching bye
