This is ridiculous on your end tbh.
If you disable V-sync/frame caps with ANY modern GPU and let it go wild to that extent you'll get coil whine. That's far, far beyond the refresh rate of any current monitor and absolutely the one you've claimed to use. You need to start capping your frames to your monitors refresh rate, it should substantially reduce any problems. You can do this via RTSS/Afterburner or other means if you don't want to enable v-sync. You're also running your card far outside of any adaptive sync tech ranges, your test is not viable and will not help you RMA.
There's such a thing as tech issues but what you're describing is self inflicted.
In the now distant past there used to be a benefit to going frame-wild as they could improve your personal performance on certain engines in multiplayer, that's really not the case anymore. Higher frames might reduce latency in some titles at best, but again unless you're hyper competitive with a monitor to match in very particular games it's irrelevant.
