[SOLVED] What is maximum rpm fan for a gpu?

[Privates]

Hello

got XFX RX 480 8GB Black Editions, it got switch button for performance or steatlh (i dont have enough information which side to A or B)

first come bios switch in on the right side, testing on Assassin's Creed Odyssey set ultra got 45-50 fps playing on 1920x1080 and see metric overlay in radeon software, and got result
Temperature 90 degree 'ish
Fan like 2000-2500 rpm

change my bios switch to left side and testing same game with same setting, got
Temperature 70 degree 'ish
Fan blowing like 3500 - 4000 rpm
(so i'm guessing left side switch is performance mode)

but i'm curious what is maximum rpm for a gpu? Because 4K rpm is very loud and i'm worried it will break/bounce at some point, i dont know how to change rpm to percentage in radeon software setting, i think it's not there because i'm looking here and there and found nothing.

or, should i use stealth mode, fan is silent or stealth, but it sure hot as hell because i can feel the heat touch my arm (i'm putting my case in the right side of monitor where my hand near it because using mouse. Is it safe to using gpu at 90 degree 'ish? because some times it hit 94

Use MSI Afterburner you can control the fan. 90C+ is definitely high clean the gpu and try undervolting.

I run my RX480 @ 1305MHz and 1040mV. Under load, it sits around 74C @ 1200rpm. Roughly 24C ambient temp in my room.

Well, clearly there is something wrong with my gpu, in order to get 70C my fan hitting 4K rpm. Time to change thermal paste?

I should've included that a year ago I repasted my GPU because it was hitting 85C @ 2400rpm fans. It wasn't throttling, but it was louder than I wanted. I can't even tell/hear my GPU fans are running at 1200rpm. (they obviously turn off below 60C(?))
