7970 coil whine, a way to fix it? *solved*

EDIT: found a fix:

a little update guys

As you know, my card had pretty bad coil whine. i was able to fix it simply by letting my pc stay overnight on a crysis main menu screen, where the coil whine was at its worst. Did this 3 nights in a row and now its whisper quiet.

Be careful tho, card heats up pretty fast using that method, so set up a custom fan profile or just use a solid 80-100% fixed fan speed. I used 70% fan speed, vrm's hit 80c, core 75c.

Worth a shot before rma smile.gif

Im running with gigabyte 7970 windforce oc gpu and it has a ***** of a coil whine. Ive been searching for an answer to my problem couple of hours now and seems like there's a way to fix coil whine. Nail polish or hot glue on capacitors/caps seems to be it.

I Applied a dab of hot glue on top of these as warked above, but it did nothing. Coil buzz was still there. Did i do something wrong or it just wont work for me?
Ive tried my card with 4 different psu's, earthwatts 500w, xfx core 850w, super flower golden green 600w and some chieftec psu. So the problem is not the psu.
I have the rma option still, removed hot glue without leaving any marks on pcb, but id rather not rma it cause my card overclocks so well, 1320/1650 benchmark stable without artifacts, 1.281v 1280/1600 fully game stable(few hours of bf3). Asic is little above 83
Do i have any other option left to try? Coil whine on this one is intolerable for 24/7 use, so i will try every possible way if theres any.

I've heard nothing about fixing the whine this way.. but even if it did fix it I wouldn't do it.

You're talking a $480 GPU here man.. if you have noise and you want to get rid of it - RMA it before you ruin it with nail polish and hot glue goop.

At least that's my opinion...

Either way, hope you get it quieted down!

There's no fix. High end cards have a tendency to whine a bit when pushed hard. Return it for another card if it is very annoying.

Well, if there's no way to ger rid of it, i will rma it. The nail polish/ hot glue trick worked on some nvidia and amd older gpu's so i gave it a spin.

Link above shows some guy got rid of that squeeling using nail polish. Hot glue is supposed to work too.

The nail polish trick is meant for open chokes, not sealed ones.

This makes a LOT more sense to me! Still wouldn't do it myself, if under warranty.. but after - sure why not!
