Unsure if this was happening before the update or after but here it goes:
I have the sapphire radeon 7870 HD card, with two fans.
One fan works, the other fan does not. On start up, both fans do a quick spin, with the working one continuing to spin.
If I open Radeon global overdrive settings, I am able to manually boost my fan speeds up to 80%, causing the second fan to finally work.
Anything less than 80% and the fan does not work.
My first guess is that it is a power issue with my PSU? It is a brand new 750w EVGA nova
Second guess is that it is a new default, where if the card gets too hot, the second fan kicks in (which I doubt is the case).
any insight to this is helpful, and I've already submitted a ticket, just thought I would pick some community members brains.
