I always use Windows 10 x64 for mining. I m thinking about to use Simple Mining OS because I bought a SRRv2. I know there is 2 USD fee for per rig. No problem. All of my GPUs are NVIDIA. I use EBWF miner.
-How to overclock for GPUs ? I use MSI Afterburner on Windows OS.
-How to change fan speed of the GPUs ? (I have to use %85 fan speed on one of my rigs.)
As easy as this

Make sure you use the slider to adjust the power. Don't manually type it in because it will not work. If you manually type it, the changes won't be applied.
