Sorry for bad english. I dont know were is Russian AMD forum.
My videocard MSI radeon r9 290 gaming 4g
I used driver 17.5.1 and I could regulate temperature and fan speed.
After I update AMD drivers it's gone.
I reinstall windows 10 and install 17.5.1 driver but nothing has changed.
How can I return these settings?
This is something we cannot reproduce inhouse, so I'm at a loss to understand what could be the root cause.
May I recommend you try the latest driver available for your product and see if that helps?
