00:00:00.120 --> 00:00:06.520
coil wine or coil noise is a phenomenon observed by the owners of All

00:00:04.120 --> 00:00:10.400
Electronics in general but in particular graphics cards that can be freaking

00:00:08.760 --> 00:00:14.440
annoying I mean I'm talking more annoying than this voice I'm doing right

00:00:12.080 --> 00:00:18.640
now sorry electromagnetic coils can act as Transformers or inductors and in the

00:00:16.760 --> 00:00:23.680
case of video cards the coils in question are acting as inductors meaning

00:00:21.000 --> 00:00:27.720
that they are trying to resist changes in the electric current passing through

00:00:25.279 --> 00:00:32.880
the making power delivery more stable these coils have a a resonance at which

00:00:31.000 --> 00:00:37.280
they can actually physically vibrate or resonance frequency and since electronic

00:00:35.120 --> 00:00:41.640
components are going to be receiving variable current a varying magnetic

00:00:39.640 --> 00:00:45.280
field exists around the coil and when these magnetic forces affecting the coil

00:00:43.520 --> 00:00:49.800
become strong enough which in the case of video cards usually occurs when it's

00:00:47.399 --> 00:00:54.600
working harder it will cause that coil to vibrate and in some cases that

00:00:51.320 --> 00:00:57.559
vibration can emit a high-pitched noise

00:00:54.600 --> 00:01:02.719
like it can be especially noticeable in certain applications like games where

00:01:00.000 --> 00:01:07.280
video card will be under varying amounts of load which will cause the card to

00:01:04.479 --> 00:01:12.840
whine at a variety of different high pitches and can degrade your overall AAL

00:01:10.680 --> 00:01:18.640
experience while using particularly open back headphones or speakers so the next

00:01:16.119 --> 00:01:22.520
question I always get is okay so lus I understand what coil wine is oh how do I

00:01:20.799 --> 00:01:27.640
fight it how do I get rid of it the unfortunate answer is that once you got

00:01:24.479 --> 00:01:29.560
it it's kind of like ants you want ants

00:01:27.640 --> 00:01:34.159
no you don't there's not a lot you can do to to get rid of coil wine in some

00:01:31.720 --> 00:01:39.399
products damping or even doing things like applying silicone over top of the

00:01:37.159 --> 00:01:43.759
offending component has shown a reduction in the amount of vibration and

00:01:41.240 --> 00:01:49.759
therefore coil wine produced and some power supplies have been known to react

00:01:46.960 --> 00:01:53.759
better or worse with different other components in the system to cause more

00:01:51.640 --> 00:01:59.039
or less coil wine in either of those components but this is a very extreme

00:01:57.039 --> 00:02:03.680
solution replacing your power supply every time that causes coil wine with a

00:02:01.039 --> 00:02:08.840
particular component and the unfortunate thing here is that outside of very

00:02:06.520 --> 00:02:13.480
extreme cases of coil wine most manufacturers will not fulfill an RMA

00:02:11.120 --> 00:02:17.160
for an affected product and even if they did it's likely that it would be

00:02:15.239 --> 00:02:21.920
considered normal for that product and the one that you get in return is going

00:02:19.000 --> 00:02:26.239
to be the same anyway so in the case of computer hardware your only real defense

00:02:24.519 --> 00:02:31.080
is to look into the products that you plan to purchase beforehand and make

00:02:28.400 --> 00:02:35.959
sure that other users are not reporting coil wine issues certain individual

00:02:33.800 --> 00:02:39.720
products are definitely affected worse than others in the case of graphics

00:02:38.360 --> 00:02:43.599
cards it might be a particular manufacturer or a particular board

00:02:42.040 --> 00:02:48.280
design that might be used across a variety of Manufacturers but you want to

00:02:46.560 --> 00:02:53.319
watch out for which ones are getting good reports from people and which ones

00:02:50.319 --> 00:02:55.239
are not then don't assume you're safe

00:02:53.319 --> 00:02:59.239
just because you buy a you know a non- reference card from a good manufacturer

00:02:57.480 --> 00:03:01.720
as with anything in life check those reviews online line before dropping a

00:03:00.599 --> 00:03:07.519
bunch of your hard earn money on a product that may disappoint you down the line or buy from somewhere with a solid

00:03:05.519 --> 00:03:12.239
return policy so if you do need to swap it up for something else you will be

00:03:09.560 --> 00:03:17.319
able to one more tip though about coil line is make sure that you've nailed it

00:03:14.280 --> 00:03:19.599
down to the right component often with

00:03:17.319 --> 00:03:23.319
very high frequency noises it's difficult to locate exactly where

00:03:21.200 --> 00:03:27.319
they're coming from so you might think that the coil line is being caused by

00:03:25.400 --> 00:03:32.000
the PCB of your graphics card but maybe it's actually the fan above it that's

00:03:29.480 --> 00:03:35.439
winding or the motherboard chipset below it or or whatever else you got to really

00:03:33.760 --> 00:03:38.959
get your ears in there and figure out where it's coming from speaking of

00:03:37.439 --> 00:03:44.599
figuring out where it's coming from I bet you guys didn't see this sponsor

00:03:40.959 --> 00:03:46.799
spot coming from me today's episode

00:03:44.599 --> 00:03:51.280
sponsor is Cooler Master they've got a wide range of reliable cases power

00:03:49.000 --> 00:03:54.879
supplies air and liquid coolers like their neptun 240m which we actually

00:03:53.319 --> 00:03:58.400
talked about a fair bit is great for keeping your CPU cool and they've also

00:03:56.640 --> 00:04:03.519
got peripherals for gamers and enthusiasts alike for example their Nova

00:04:01.040 --> 00:04:06.400
touch tkl that everyone keeps asking what is that keyboard in your video what

00:04:05.079 --> 00:04:10.239
is that keyboard in your video you guys got to check out our ultimate keycap

00:04:08.400 --> 00:04:14.480
replacement guide over on the lonus tech tips Channel because we cover that

00:04:12.680 --> 00:04:18.680
particular keyboard why it's so special and how you replace all the keycaps on

00:04:16.120 --> 00:04:21.959
it and make it look freaking awesome all the information about how you can use

00:04:20.239 --> 00:04:25.639
their products most effectively and what each of them is meant to accomplished

00:04:24.120 --> 00:04:30.080
can be found over at The Cooler Master website or at CMU Cooler Master

00:04:28.720 --> 00:04:33.639
University they got a bunch of really great educational articles over there

00:04:31.919 --> 00:04:38.520
and what's good about it is it's not just OMG by Cooler Master all the time

00:04:36.479 --> 00:04:42.520
every day it's actually seeking to help you make a more educated purchasing

00:04:40.120 --> 00:04:45.600
decision regardless of what you're shopping for so thanks to Cooler Master

00:04:44.120 --> 00:04:48.520
for sponsoring this episode as fast as possible you guys for watching and like

00:04:47.400 --> 00:04:52.080
this video if you liked it dislike it if you disliked it leave a comment if you have suggestions for future fastest

00:04:50.639 --> 00:04:56.000
Possible episodes just like this one or different from this one whichever you prefer that's the point of suggestions

00:04:54.720 --> 00:04:59.440
it doesn't have to be exactly the same thing I mean if everyone suggested I keep making the same video over and over

00:04:58.199 --> 00:05:04.080
again I would keep making the same video over and over again and no one wants to see that thanks for watching bye
