1
00:00:00,120 --> 00:00:06,520
coil wine or coil noise is a phenomenon observed by the owners of All

2
00:00:04,120 --> 00:00:10,400
Electronics in general but in particular graphics cards that can be freaking

3
00:00:08,760 --> 00:00:14,440
annoying I mean I'm talking more annoying than this voice I'm doing right

4
00:00:12,080 --> 00:00:18,640
now sorry electromagnetic coils can act as Transformers or inductors and in the

5
00:00:16,760 --> 00:00:23,680
case of video cards the coils in question are acting as inductors meaning

6
00:00:21,000 --> 00:00:27,720
that they are trying to resist changes in the electric current passing through

7
00:00:25,279 --> 00:00:32,880
the making power delivery more stable these coils have a a resonance at which

8
00:00:31,000 --> 00:00:37,280
they can actually physically vibrate or resonance frequency and since electronic

9
00:00:35,120 --> 00:00:41,640
components are going to be receiving variable current a varying magnetic

10
00:00:39,640 --> 00:00:45,280
field exists around the coil and when these magnetic forces affecting the coil

11
00:00:43,520 --> 00:00:49,800
become strong enough which in the case of video cards usually occurs when it's

12
00:00:47,399 --> 00:00:54,600
working harder it will cause that coil to vibrate and in some cases that

13
00:00:51,320 --> 00:00:57,559
vibration can emit a high-pitched noise

14
00:00:54,600 --> 00:01:02,719
like it can be especially noticeable in certain applications like games where

15
00:01:00,000 --> 00:01:07,280
video card will be under varying amounts of load which will cause the card to

16
00:01:04,479 --> 00:01:12,840
whine at a variety of different high pitches and can degrade your overall AAL

17
00:01:10,680 --> 00:01:18,640
experience while using particularly open back headphones or speakers so the next

18
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

19
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

20
00:01:24,479 --> 00:01:29,560
it it's kind of like ants you want ants

21
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

22
00:01:31,720 --> 00:01:39,399
products damping or even doing things like applying silicone over top of the

23
00:01:37,159 --> 00:01:43,759
offending component has shown a reduction in the amount of vibration and

24
00:01:41,240 --> 00:01:49,759
therefore coil wine produced and some power supplies have been known to react

25
00:01:46,960 --> 00:01:53,759
better or worse with different other components in the system to cause more

26
00:01:51,640 --> 00:01:59,039
or less coil wine in either of those components but this is a very extreme

27
00:01:57,039 --> 00:02:03,680
solution replacing your power supply every time that causes coil wine with a

28
00:02:01,039 --> 00:02:08,840
particular component and the unfortunate thing here is that outside of very

29
00:02:06,520 --> 00:02:13,480
extreme cases of coil wine most manufacturers will not fulfill an RMA

30
00:02:11,120 --> 00:02:17,160
for an affected product and even if they did it's likely that it would be

31
00:02:15,239 --> 00:02:21,920
considered normal for that product and the one that you get in return is going

32
00:02:19,000 --> 00:02:26,239
to be the same anyway so in the case of computer hardware your only real defense

33
00:02:24,519 --> 00:02:31,080
is to look into the products that you plan to purchase beforehand and make

34
00:02:28,400 --> 00:02:35,959
sure that other users are not reporting coil wine issues certain individual

35
00:02:33,800 --> 00:02:39,720
products are definitely affected worse than others in the case of graphics

36
00:02:38,360 --> 00:02:43,599
cards it might be a particular manufacturer or a particular board

37
00:02:42,040 --> 00:02:48,280
design that might be used across a variety of Manufacturers but you want to

38
00:02:46,560 --> 00:02:53,319
watch out for which ones are getting good reports from people and which ones

39
00:02:50,319 --> 00:02:55,239
are not then don't assume you're safe

40
00:02:53,319 --> 00:02:59,239
just because you buy a you know a non- reference card from a good manufacturer

41
00:02:57,480 --> 00:03:01,720
as with anything in life check those reviews online line before dropping a

42
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

43
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

44
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

45
00:03:14,280 --> 00:03:19,599
down to the right component often with

46
00:03:17,319 --> 00:03:23,319
very high frequency noises it's difficult to locate exactly where

47
00:03:21,200 --> 00:03:27,319
they're coming from so you might think that the coil line is being caused by

48
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

49
00:03:29,480 --> 00:03:35,439
winding or the motherboard chipset below it or or whatever else you got to really

50
00:03:33,760 --> 00:03:38,959
get your ears in there and figure out where it's coming from speaking of

51
00:03:37,439 --> 00:03:44,599
figuring out where it's coming from I bet you guys didn't see this sponsor

52
00:03:40,959 --> 00:03:46,799
spot coming from me today's episode

53
00:03:44,599 --> 00:03:51,280
sponsor is Cooler Master they've got a wide range of reliable cases power

54
00:03:49,000 --> 00:03:54,879
supplies air and liquid coolers like their neptun 240m which we actually

55
00:03:53,319 --> 00:03:58,400
talked about a fair bit is great for keeping your CPU cool and they've also

56
00:03:56,640 --> 00:04:03,519
got peripherals for gamers and enthusiasts alike for example their Nova

57
00:04:01,040 --> 00:04:06,400
touch tkl that everyone keeps asking what is that keyboard in your video what

58
00:04:05,079 --> 00:04:10,239
is that keyboard in your video you guys got to check out our ultimate keycap

59
00:04:08,400 --> 00:04:14,480
replacement guide over on the lonus tech tips Channel because we cover that

60
00:04:12,680 --> 00:04:18,680
particular keyboard why it's so special and how you replace all the keycaps on

61
00:04:16,120 --> 00:04:21,959
it and make it look freaking awesome all the information about how you can use

62
00:04:20,239 --> 00:04:25,639
their products most effectively and what each of them is meant to accomplished

63
00:04:24,120 --> 00:04:30,080
can be found over at The Cooler Master website or at CMU Cooler Master

64
00:04:28,720 --> 00:04:33,639
University they got a bunch of really great educational articles over there

65
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

66
00:04:36,479 --> 00:04:42,520
every day it's actually seeking to help you make a more educated purchasing

67
00:04:40,120 --> 00:04:45,600
decision regardless of what you're shopping for so thanks to Cooler Master

68
00:04:44,120 --> 00:04:48,520
for sponsoring this episode as fast as possible you guys for watching and like

69
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

70
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

71
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

72
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
