Question Sapphire Rx 570 4gb display is working normally, but fans and led not working

[Uncle_Klevv]

I have a Sapphire Rx 570 4gb Nitro+ that I've been using for about 3 years.

A graphic driver error occurred while booting recently, the fan and LED have not worked since then.

But the display works normally.

I tested it with occt, but the fan didn't work even if it went over 158°F. (70°C )

I updated the graphics driver, but it was the same.

It didn't work the same on other computers.
