Welcome to the party! Thanks for the cat tax!
Sucks about the 4090. Maybe you can play around with undervolting it to see if you can minimise the sound a bit. Underclocking and/or undervolting won’t get rid of coil whine completely, but you’ll observe noticeable improvement.
it's not affecting me that much when i'm fully immersed in VR due to wearing headphones, but when i'm using it with local LLM for chats the noise can be unbearable. Not sure how undervolting can affect that particular use case yet so i've never done it.
Do you get coil whine on idle? Or only under load? Maybe just a frame rate limit might reduce your coil whine
Totally no whine on idle, only under load. Like i said in other reply, on stable frame rate it can almost be like white noise due to constant noise, but when running LLM it makes a very distinctive rhythmic noise, and the noise pattern is different with every model and its VERY annoying.
Yeah maybe frame rate limit, power limit, under volt, under clock... Those kinds of things might help
