When installing these new drivers idle clock speeds are not working properly. What used to be idle clocks of 300/150 is now 500/1375 or lower depending on your card resulting in higher temps and a louder fan usage.
A fix has been discovered that will allow you to use the new drivers and also still benefit from having lower clocks until AMD release a hotfix driver.
First install the drivers+caps.
Once that is done start up CCC, go to overdrive and apply 300 core and 150 memory clocks.
After this go to preset, add preset, name the preset idle, put the tooltip as 2dclocks, under location leave all items ticked, then assign a hotkey. I used F5. Click save.
After that go to preferences in the top right of CCC, then hotkeys. Click idle and go to edit. In with Hotkey press F5, Click ok.
Now whenever you quickly need to apply idle clocks, just press Alt+F5 twice.
