After a few second Fan Stop turns on and evrything is as usual. Is it normal?
Sapphire Rx 570 pulse
Ryzen 5 1600
Gigabyte B450 Aorus M
Seasonic S12II 620W
20.2.2 driver
Please update to 20.4.2. It may help you sir.
My Rx 580 used to do this on boot up and during wake up events. The fans would spin up and then slow down. I think its likely normal. If you're worried contact tech support.
