00:00:07.240 --> 00:00:13.480
now coil wine is something that I've complained about and talked about a lot

00:00:10.880 --> 00:00:18.800
on lineus Tech tips in general but I don't think I've ever actually

00:00:15.520 --> 00:00:21.519
demonstrated what it is so this is a

00:00:18.800 --> 00:00:26.880
graphics card this is a 7970 reference card and my observation with the

00:00:24.359 --> 00:00:30.320
reference cards for 7970 has been that there's a fair amount of coil wine so

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

00:00:33.920 --> 00:00:39.840
I should leave it to individual users to decide if it's something that will

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

00:00:41.879 --> 00:00:49.079
installed in a case right now so the case will help to reduce some of this

00:00:46.039 --> 00:00:51.039
noise and it's particularly offensive if

00:00:49.079 --> 00:00:55.160
you do have a high sensitivity to high-pitch noises whereas if you don't

00:00:53.359 --> 00:00:59.120
have that sensitivity then coil wine is a lot less bothersome once you have it

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

00:01:04.040 --> 00:01:10.159
pretty much it like some power supplies will react worse with the power delivery

00:01:08.439 --> 00:01:14.080
system on a particular video card and cause it to wind more or less um but

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

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

00:01:22.280 --> 00:01:29.200
around very ghetto solution for doing that okay sorry about that guys so I'm

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

00:01:31.759 --> 00:01:40.479
this case it's not a particularly demand demanding game this is Halo

00:01:36.880 --> 00:01:41.640
1 see there you go there's some Halo 1

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

00:01:43.520 --> 00:01:47.079
you think of it

00:02:00.640 --> 00:02:07.280
so this is why I don't like coil wine it's particularly bothersome in

00:02:04.640 --> 00:02:11.280
applications where it fine-tunes its whininess to whatever you're doing so

00:02:08.920 --> 00:02:11.280
check this

00:02:19.800 --> 00:02:25.959
out so you can see it actually corresponds to my movement so there you

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

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

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

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
