sounds like capacitor noise, real high pitched, and only happens when playing 3d, core clock seems to not affect it. when i removed the mod, the sound went away.
it was too noisy to live with.

anyone elses 7900gt make funny noises after 1.4v mod?

rawr, someone is cranky....
yeah, the extra voltage might (probably is) causing more heat, so the fan probably sped up. quite normal. btw, how much more OCing did you get out of it?
Actually, I'm getting the same sort of noise with my X1800XL that's watercooled so it might not be the fan.
I have only ONE variable speed fan in my system which is the CPU fan but just when I start a 3D app the CPU fan speed doesn't change cause I checked. The other fans in my system are fixed speed. The sound only started coming after I switched to this video card. I heard the sound when it was aircooled so I figured it was the fan. After I switched to watercooling I still get the sound so it wasn't the fan.
Understand???
im not retarded, i have a artic cooling NV silencer on my card. its not a fan noise, its very clearly a leaky capacitor or similar electronic noise.
A capacitor can make noise and eventually explode if over-volted too much!
But, it would be odd if this happened by just 0.1V over-volt.
Manufacturers usually use components with some margin. If the voltage across the cap is 1.3V, they don't use a 1.4V cap (even if it existed).
How much over-volt are we talking about here?

So can a card running at stock can make a capacitor noise?? Cause mine made the noise even at stock.
Can I suggest that you guys open the case carefully; power on your PC; start the 3D application that causes the noise; after the noise starts, stop the fan momentarily with your finger placed on the center of the spinning fan (don't touch the end of the blade as it can hurt)?
Just to make sure that it is not the fan.

A capacitor that makes noise is not a happy capacitor! It is either defective or is being used incorrectly (too much voltage across it).
Seriously?? Cause like I said, it was making the noise whenI first got the card and tried it at stock levels.
I may have given incorrect information. 
An electrolytic capacitor will make noise and eventually explode if you power it up with wrong polarity. I don't know if the same thin can happen by just applying extra voltage to it.

***EDITED: Whoops the quotation was not intended***
I know what you are talking about, ive read about it before, there was even a thread created on here not long ago where someone experienced this with their X1900 series card. It sounds like a high pitched squeal, in fact i have the same problem with my new DELL laptop when plugged into the mains, although it is intermittent.
I dont believe it has anything to do with the capacitors that are used, its something to do with the voltage regulation on the card itself, as a larger amount of current is being drawn. Don?t forget the voltage supplied to the GTX is higher than the GT with the 7900?s, so the components used (specifically with regards to voltage regulation) will differ on the two cards.
Its clearly being stressed and produces this high pitched squeal, the same thing happens to Power Supplies that are highly stressed and put under heavy load.

YES! I remember that discussion vividly! What I forget is whether the OP had a friend or himself seriously believed the "let the smoke out and it dies" theory, or if it was just a joke! Either way, good times
.Someone doesn't understand how circuits work. Coil whine is a cause of annoying sound in certain computer configurations at specific voltages...
Sounds just like a stressed out voltage regulator. You will probably be okay as I've seen quite a few high end cards do this through out the years...
I have to agree with the power regulator/coil explanation. I know very little about electronics, but I work on high power industrial circuits (light rail vehicles actually) and have an electrical background and I can say I have never heard a capacitor make a sound, except when it explodes... Coils, transformers and induction circuits however all produce a hum, buzz or I suppose on a small scale, a squeal.
