Coilwhine fix by drilling open chokes?

[Chemz11]

Some say to fix coil whine you have to undervolt, overvolt your graphics card, or change powersupply to fix the coil whine. Sometimes these solutions don't work. Has anyone thought about drilling those chokes open and putting in some compound to keep the coils from moving? I'm thinking about doing that, the compound I think I might use is arctic silver alumina. Should I or shouldn't I do it

Update:
I've just drilled through the first choke, I kinda struck the coil, just a little just a tiny scratch. Applied compound and ran it through heaven still whining, going to go through next chokes.

No you generally shouldn't use a drill on a GPU component of any sort.

You can try adding some silicone caulk to stabilize it perhaps, but that is about as far as I would go.

Yep, I've had good success just putting some hotmelt glue on them (assuming it's not near anything that get's too hot). As Eximo says, silicon caulk would be better.

Hi
Are you talking about drilling down the center of the coil ?
If so ,the center of the coil is generally a ferro magnetic former and if you drill it it the coil will cease to work.
Coil whine is caused by the coil vibrating at its resonant frequency and changing the load on the coil alters the frequency, which if it moves away from the resonant frequency will reduce or stop the coil whine.
As nitrium says another way is to stop or reduce the coil itself vibrating by using glue .

Did you put it on the chokes?

Only drilling the caps that are covering the coils so that theres an opening for me to apply the compound

In theory it may work,but you would need to be extremely careful when drilling that you did not drill into the coil by accident.

Yeah have done in the past. They don't get very hot in of them themselves, but obviously can do if they're close to the VRMs or RAM or whatever. It was a 8400GS and 8800GT I did it on BTW, so it's been a while! I'd use epoxy or silicon caulk if I was doing it now, since these glues are much more temperature resistant.
