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.
