The two are related because the power delivery changes, and neither is a "fault". It is commonly heard obnoxiously when the work being done by a GPU is slight, and FPS is high, but the reverse can also be true too, I suppose. because the power being used by the GPU when this happens has changed. The coil whine changing when the FPS drops is natural. It's not really a problem, just something that happens because of the switching frequency of the power delivery, and as such, it's largely unavoidable 100%.

Might it be that the SF450 PSU I have in my build is not providing the GPU with enough voltage/a steady stream of voltage?
However, when I pair the GPU in a different setup with a TX750V2 PSU, the coil whine is not being emitted. It's basically like the frame freezes for some ms, then continues on.Īnyone have suggestions for solutions in regards to this? Give the GPU more voltage/undervolt it? Raise/decrease the power limit? I have isolated the coil whine to the GPU, as the noise is 100% coming from there. That is - at the exact point when the game micro stutters, the coil wine stops, then starts up when it's all smooth again. When I play games, I can hear coil whine from my GPU in sync with when it stutters. My finished mini-ITX build works great except for this weird micro stutter going on when I play games.
