--- Comment #1 from Christian Birchinger (joker at 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.
