Fan at my 7850, that 4 monts old, didn’t spin until temperature rise up to 91°C. Than it start spinning with 100% speed until the temperature drop to 65°C. Than – stops.I try use OverDrive to set up speed manualy, but i can change speed of the fan only between 78-100%. if I set the speed below 78% – the fan stops.
Update motherboard BIOS? – Yes
Update drivers? – Yes
Uninstall drivers with DDU in safe mode, and than install latest? – Yes
Uninstall all other VGA related additional software? – Yes
Nothing doesn’t help.
What else i can do?
