New GTX 770 Makes a Weird Buzzing Noise when Benchmarking

Hey guys,

I upgraded my PC just 4 days back and I now have an ASUS DirectCU II OC GTX 770 w/ 2 GB, an Intel i5 4670K and an ASUS Z97 motherboard. It has been gaming fine and I otherwise have no issues but today I decided to run benchmarks on the card.

Both my CPU and GPU are at their stock clock settings as I have not overclocked them yet. However, when I ran the Unigine Heaven 4 benchmark I noticed that the card makes a brief 20 second buzzing noise near the beginning of the benchmark.

It starts off faint, but eventually gets noticeably louder. It then becomes faint again and disappears for the remainder of the benchmark.

I am not sure if this sound is due to the fans of my GPU or the coil but from the examples of coil whine I have heard from videos on Youtube, this sound appears to be completely different. It is a lower pitched buzzing noise as opposed to the high pitch squeals due to coil whine.

Strangely enough, when I ran 3DMark and Furmark, it did not make these noises at all even on the highest of settings. Also, it doesn't make the sound when I play games either.

To show you guys exactly what I am hearing, I have posted the recording on Soundcloud. The noise starts off at the 24 second mark and gets louder over time and then disappears.

Is this a problem I should be worried about, or is it normal? I can still get it replaced from the store I bought it from so that isn't a problem but should I even bother in the first place?

Thanks in advance for the help! :D

[EDIT:] I Just realized that when I run 3DMark I also get that same noise when I ramp up the 3DMark settings.

I have an MSI GTX 770, mine makes buzzing noises at high loads as well. I'm pretty sure that's just the sound of your GPU sucking up as much power as it can, mine always makes a low buzzing sound when I'm running at max or near max load.

I first noticed it while playing Fallout/Skyrim with ENB's enabled. I got worried and started searching around and saw that it happens to many other ENB users, so I started monitoring my GPU stats all the time with my keyboard. (LCD display on it!) I eventually started to notice that the GPU starts to buzz while it was at 90+% power usage, it would buzz in stress tests and in intensive games.

I've had my card for a few months now and it's running just fine. I don't think you need to worry about the buzzing noise.
