hmmm… thanks for infos… so powerfull enough components.
And you can still not enable DLSS and Frame-Gen ?
I recommend to let run stress-tools, which realy check all aspects of the card. These noise you mention, it can come from the PSU , but also from the GPU. In very high load it can possible happen ( may be the english word is: coil whine ? ) , but together with a reboot… hmmm…
In case you can never again reproduce the reboot situation and you executed some stress-tests, then you can may be relaxt and it was a “one time thing”. A real explanation about more fps without enabled Frame-Gen I not realy have in that case… may be the “reboot” cleaned somewhat what former caused low fps
