Why do games cause coil whine and benchmarks dont?

[Cyber2B]

When I run RB6 I hear super coil whine but when I ran superposition I only heard the whirring of my fans

Any reason for this? Don't benchmarks push the hardware even more then games?

different 3d rendered images put different amounts of load on the components. coil whine is the result of vibration and the whine can differ in pitch depending on the load on the component producing the sound.

depends on the power draw and frequency resonance

coil acts like an electronic spring, resisting current changes
different load/spikes will cause it to vibrate (and make noise) if the coil is not potted well

if you try a different bench it may make more or less noise

Benchmarks are useful but don't answer all questions. I assume what you experience is a whine coming from a higher framerate (looking at walls and such).
Basically there is always a whine, but most of the time outside of our humans audible frequency range, and different loads can change that. And the problem with the coils (or inductors) from a physical standpoint is that the only way to lower their vibration means to increase their temperature (or simply buy a card that is known to have very little whine).

Concerning benchmarks i can also add that i just recently increased my VRAM frequency and Superposition was working just fine with a higher score. But after playing half an hour of Dying Light i encountered artifacts. Its a complex matter and one test never gives the whole picture.

I had coil whine with a gtx980 I used to own.

As mentioned coil whine is usually caused by high fps. Some badly programmed games don't limit the fps in menu's so it can go above 500 fps or perhaps the game is easy to run so high fps. Superposition likely gets less than 60 fps as it is harder to run, so no coil whine.

I'm not sure about AMD but Nvidia has an option to force vsync on for individual games. It might help with rb6.

What solved it for me was using phono outputs to balanced xlr inputs of my speakers.

Just try using Nvidia adaptive or fast sync for your games. Configure this within nvidia control panel
