770 Phantom buzzing under extreme load

[GAM8LE]

Hi guys,

Bit of a weird one. I was running a test on 3dmark and I noticed a faint buzz that started when the test started. Its hard to explain the noise, its quite faint but is a buzzing sound, or maybe if you imagine the sound of an electric cable, very very faint version of that, almost inaudible.

It happens when the gfx card hits 60% power usage and max core usage.

Should I be concerned?

I stopped the test and put the two gfx card cables on different rails, and changed the cables in case something was damaged but its still there.

Maybe its normal under extreme load, I don't know. It could even be the processor in it ticking away in really not sure

It was hitting around 60 degrees and the fan was on 37%. If I put the fan on 100% now.....just did, no unusual noises.

I did a bit of googling and found something called coil whine when it really gets pushed high so im thinking it might be that, which apparently isn't a sign of anything bad, just an annoyance.

Hmm, anyone with the same card or equivalent experience the same under almost 100% power load and core load?


Regards

Yeah , my 290 makes a buzzing noise , my 780ti makes a buzzing noise, in fact EVERYONE i know with a high end card be it a 7990 or a 780 makes a buzzing noise when vsync is off and the cards are loaded, i think the people who claim their cards don't emit any coil whine are either deaf or they have fans that drown it out.

I think some cards just have noisier caps/coils than others , its totally normal and nothing to worry about.

Not everyone has coil whine. Depends the psu.

You can fix coil whine with some neutral cure silicone rubber on the chokes

Thankyou very much for replying! I was a bit worried.

Based on your advice I performed a test.

3dMark - the noise is there but there is no vsync as my global setting is "off"

3dMark - Global v-sync setting to "On" and program setting to "On" - no noise with the same power usage.

Phew, I knew I would get a quick knowledgeable response on this forum.

Thanks a lot
