Need help. Fans running at 18 to 20 percent and cant get them to manually speed up. I have tried trixx and msi. I also used -fanmin 80 in claymore and nothing will work. I had the latest drivers installed and thought that might be the issue so i uninstalled and reinstalled 15.12. Im on windows 10 and this rig has 2-290 and 2-380x cards in it. Any suggestions 
If you have AMD cards, you need to plug in a monitor or dummy plug in to the VGA connected to primary VGA PCI-E x16 slot for the AMD drivers to be able to read and set the cards fan speeds and temps.
Also you will need to set the default video in the bios to PCI-E as it will be set to VGA.
