4090 - CoilWhine (is it bad?)

Coil whine is caused by the vibration of electromagnetic coils (Inductors) inside electronic components such as PSUs, Graphics Cards, Motherboards, etc. These coils are used to regulate the flow of electricity through the component and are an essential part of its operation.

Coil whine doesn’t directly affect your hardware, including your GPU, in a harmful way. However, it can be an indicator of underlying issues that could potentially lead to damage over time.
How old is card?
Does it only happen when you run a benchmark? None at idle?
I ran a benchmark where the FPS ranged from 350-400. The GPU: GAINWARD Phantom GS.

This is a common issue in GPUs, especially in high-performance models that have more powerful and complex power delivery systems. The noise is typically more noticeable when the GPU is working harder, such as during high-intensity gaming or benchmarking.
What refresh rate is monitor? One way is to limit the frame rate to just under you monitors max refresh rate as then it won't push card as hard unnecessarily. That can help with coil whine as GPU won't need to try as hard.

All my quotes are from here:

Is it annoying to you? You are the one who has to hear it. One answer is to use headphones and block it out. Though that doesn't always work, depends on headphones.
