--- Comment #1 from Christian Birchinger (joker@netswarm.net) --- This issue is also present on my system with the same card (Sapphire Radeon RX580 Nitro+ Special Edition) on a recent vanilla kernel (5.8.6).

"pwm1_enable" is 2 after a clean boot. Writing "2" to it again makes the fan speed switch between 2 speeds rapidly causing a high pitched annoying noise.
