now coil wine is something that I've complained about and talked about a lot
on lineus Tech tips in general but I don't think I've ever actually
demonstrated what it is so this is a
graphics card this is a 7970 reference card and my observation with the
reference cards for 7970 has been that there's a fair amount of coil wine so
I've had a lot of people kind of well suck it up Princess um so I but I think
I should leave it to individual users to decide if it's something that will
bother them or not bear in mind guys this card is on a test bench it's not
installed in a case right now so the case will help to reduce some of this
noise and it's particularly offensive if
you do have a high sensitivity to high-pitch noises whereas if you don't
have that sensitivity then coil wine is a lot less bothersome once you have it
there's really not a lot you can do about it some combinations of power supplies can help um that's that's
pretty much it like some power supplies will react worse with the power delivery
system on a particular video card and cause it to wind more or less um but
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
about as far away from the microphone as my voice is now so I'm going to turn my mic
around very ghetto solution for doing that okay sorry about that guys so I'm
going to position the mic right there and I'm going going to launch a game in
this case it's not a particularly demand demanding game this is Halo
1 see there you go there's some Halo 1
and I'm going to let you guys listen to the noise and you all can decide what
you think of it
so this is why I don't like coil wine it's particularly bothersome in
applications where it fine-tunes its whininess to whatever you're doing so
check this
out so you can see it actually corresponds to my movement so there you
go guys that's coil wine that's what it sounds like there's not a whole lot you
can do about it unless it's really really bad uh you usually won't get an
RMA for it so um just try and find a card that you know doesn't really whine
if you think that that kind of thing will bother you thanks for checking out this episode of lus tech tips and don't
