Honestly I just use the latest drivers with my AMD cards, as they have support for newer games. I currently have some R9 290s, R9 Furys, an RX 580 and an RX Vega Nitro 64. All worked fine with newer drivers.
What exactly is the issue you are having with them?
------------------------------------
Fan Control is just one issue R9 200 and 300 unlocked Hawaii Radeons have regarding Adrenalin Wattman. Here's an eg:

Another issue is implementing a stable VDDC and power limit. Aside from having a horrible interface, Adrenalin Wattman &^$#'s Radeon R9's.
For your info I'm running Win7 Ultimate 64-Bit SP1 totally updated. In about a years time, if 7nm arrives, I 'm considering building a new rig with Win10. In the mean time I'm not about to discard Win7 64-Bit/Sandy Bridge/Z68/i7 2700k and X-Fire 290X that has run for years consistent at 4800 to 5100 Mhz with X-Fire 290X's maxed stable without artifacts at 1105/1600/150/50 - Of course under water and you need at least a 1000 Watt PSU.
The best driver I had was the amd-catalyst-14.6-rc2-windows-june23. Worked fantastic with TRIXX until MS started updating .Netframework 4.5. Now Catalyist will not install nor will most Crimson with Wattman - Is it Win7/8 specific ? - I do not know.
I'm discussing Reference & AIB R9 200 and 300 Series Radeon's - Not modified. AMD needs give the option to disable Wattman with their Adrenalin Driver for these Cards for Win7 and 8 - Considering MS is abandoning.
1st response from DrMrLord gave me a working ground - Not Perfect but doable - Got to give that Man credit because he read my search and answered responsibly.
Big jump from a power hungry 28 Nm to 7 Nm core after 12 years running the same frequency - Humm - Big changes are about to happen within the next 2 years - Hope I live that long ;o)
Forgive my editing as I'm rather dyslectic but I know a 13 year old 28Nm ATi AMD Hawawii R9 290X Radeon can perform just as well as a Modern nVidia GTX 2070Ti, if we are allowed to do it.
