Hello all! Been lurking this thread for the last few days so I decided to join just to share my experience.
Initially got a 4080 FE and had it paired with an RM850x as well as a RM1000x that I purchased in anticipation for a 4090. The 4080 FE was virtually silent under full load.
Managed to get my hands on a 4090 FE and have tested it on a RM1000x and a HX1000i PSU.
Unfortunately, the 4090 FE has some coil whine. Not the worst I have experienced but still disappointing to see on such an expensive card. I am currently running a 13700k, MSI Z690 Edge mobo, and a 3440x1440 @ 100hz monitor. With the 4090 I enable DSR at 1.75x which is some resolution I can’t even remember, so a majority of the time I am running the card at 99% usage.
What puzzles me is that my coil whine is completely different in every application. I’ve only had the card for a few days so I haven’t tested a vast amount of titles but here is what I have gathered..
Cyberpunk max settings with DSR @ 1.75x, DLSS Quality, Frame Gen on, psycho RT. This particular case produces the loudest coil whine in this GPU. I will link a video.
Hitman 3 max settings with DSR @ 1.75x, DLSS Quality, RT on the highest setting. Some coil whine, practically inaudible unless I mush my head right up against the mesh opening of my case and listen for a few minutes. Sitting just a few feet away from my PC I can’t hear it.
Battlefield 2042 Ultra settings, DSR @ 1.75x, RT on. Practically no coil whine that I can tell.
Furmark with GPU at 100% usage and I hear nothing, same goes for Timespy.
This is a very poor quality example but this is the coil whine when playing Cyberpunk. You can hear the difference when I leave the main menu and return to the game. And yes, my computer sounds like a jet engine. I plan on disabling all of my case fans to get a better capture of the coil whine when time permits.
