00:00:07,240 --> 00:00:13,480
now coil wine is something that I've complained about and talked about a lot

2
00:00:10,880 --> 00:00:18,800
on lineus Tech tips in general but I don't think I've ever actually

3
00:00:15,520 --> 00:00:21,519
demonstrated what it is so this is a

4
00:00:18,800 --> 00:00:26,880
graphics card this is a 7970 reference card and my observation with the

5
00:00:24,359 --> 00:00:30,320
reference cards for 7970 has been that there's a fair amount of coil wine so

6
00:00:28,640 --> 00:00:36,399
I've had a lot of people kind of well suck it up Princess um so I but I think

7
00:00:33,920 --> 00:00:39,840
I should leave it to individual users to decide if it's something that will

8
00:00:37,960 --> 00:00:43,520
bother them or not bear in mind guys this card is on a test bench it's not

9
00:00:41,879 --> 00:00:49,079
installed in a case right now so the case will help to reduce some of this

10
00:00:46,039 --> 00:00:51,039
noise and it's particularly offensive if

11
00:00:49,079 --> 00:00:55,160
you do have a high sensitivity to high-pitch noises whereas if you don't

12
00:00:53,359 --> 00:00:59,120
have that sensitivity then coil wine is a lot less bothersome once you have it

13
00:00:57,879 --> 00:01:05,640
there's really not a lot you can do about it some combinations of power supplies can help um that's that's

14
00:01:04,040 --> 00:01:10,159
pretty much it like some power supplies will react worse with the power delivery

15
00:01:08,439 --> 00:01:14,080
system on a particular video card and cause it to wind more or less um but

16
00:01:12,640 --> 00:01:19,080
that's pretty much all there is to it so what I'm going to do is I'm going to position the graphics card itself uh

17
00:01:17,600 --> 00:01:24,640
about as far away from the microphone as my voice is now so I'm going to turn my mic

18
00:01:22,280 --> 00:01:29,200
around very ghetto solution for doing that okay sorry about that guys so I'm

19
00:01:27,040 --> 00:01:33,840
going to position the mic right there and I'm going going to launch a game in

20
00:01:31,759 --> 00:01:40,479
this case it's not a particularly demand demanding game this is Halo

21
00:01:36,880 --> 00:01:41,640
1 see there you go there's some Halo 1

22
00:01:40,479 --> 00:01:47,079
and I'm going to let you guys listen to the noise and you all can decide what

23
00:01:43,520 --> 00:01:47,079
you think of it

24
00:02:00,640 --> 00:02:07,280
so this is why I don't like coil wine it's particularly bothersome in

25
00:02:04,640 --> 00:02:11,280
applications where it fine-tunes its whininess to whatever you're doing so

26
00:02:08,920 --> 00:02:11,280
check this

27
00:02:19,800 --> 00:02:25,959
out so you can see it actually corresponds to my movement so there you

28
00:02:24,239 --> 00:02:30,319
go guys that's coil wine that's what it sounds like there's not a whole lot you

29
00:02:27,360 --> 00:02:35,239
can do about it unless it's really really bad uh you usually won't get an

30
00:02:32,599 --> 00:02:38,319
RMA for it so um just try and find a card that you know doesn't really whine

31
00:02:37,120 --> 00:02:45,400
if you think that that kind of thing will bother you thanks for checking out this episode of lus tech tips and don't
