Whining

[Lethalrise750]

I was curious if anyone has any fixes to coil whines. I've been told to use Hot Glue or Nail polish on the Chokes and Distributors but sort of unsure. My card has solid ferrite chokes so the coils are covered and such.

What ? I am really confused ?

Graphics cards have Ferrite Chokes, these chokes are wound coils of copper wire. When large amounts of power go through them, they can vibrate and cause noise.

Coil whine is mechanical resonance of the coil with the frequency of the signal passing through it. Physically, a coil is just loops of wire, sometimes with a core other than air. If the frequency of the signal is in resonance with the physical wires of the coil, the coil may vibrate. Oft times, the vibration is beyond human hearing (yokes in TV's can do this), other times it's in the range of human hearing.

There are many electrical parts/circuits which can cause whining noises, so don't just assume you are hearing coils. "Annoying buzzing/electrical sound" are unlikely to eminate from a coil - you have something else making noise. Whining is caused by a part (or parts) physically vibrating.

Unto itself, voltage is not going to cause a whining sound. Voltage is electrical potential (actually, EMF); current through a device is dependent on the voltage across it. With a CPU, changing the voltage probably changes the operating frequency of various components within the processor (I really don't know what is changed), however something is probably in resonance with the signal. If you can narrow down the source of the noise, you may be able to reduce or eliminate it. Try using the paper tube from a roll of paper towels to "listen" to various parts of your system to locate the source.

Good luck!

just something i dragged up from another site.

OH now I know what you are talking about . HOT glue take care of that . It works for me .

I've never tried it but blu-tak (poster tack/sticky tack) or kneaded eraser? My ferrite chokes are hot enough to melt hot glue.

(Bad Picture, I know.. My cameras battery is dead.)

The red square is where the buzzing/whining is coming from. Nothing else is whining, I'm not sure if I cover it in something will it stop the sound or not.

Maybe supper glue ? I would say if they are hot like that maybe a fan cooling them might just quiet them up some ?

I may try Super Glue since it is Acrylic.

I just added one. Mine don't make any noise though so shutting them up is the least of my worries.

FYI sticky tack and kneaded eraser are apparently a type of designer rubber. (Not the Versace kind you put on your John Thomas.)

If I were you I would just leave it alone. I used to have HD3850 that whine like a pig. I played with a hot glue and all it did was one big mess. I ended up stripping the glue off of the card. The whining you hear is normal, on both ATI and Nvidia video cards.

amen to that^
u really dont wanna risk your hardware

Yeah I ended up not doing anything and leaving it be Seemed like too much effort to fix a natural occurrence.
