Fan Control on MaximusXII Hero WiFi?

I have an AIO for the CPU hooked into the CPU fan header. I also have an AIO from my gpu hooked into the auxiliary cpu fan header. What is the least intrusive way to control these? I am leary of ASUS software due to instability and bloat. So far I had EXCELLENT results using mokichu's packages. Unfortunately he does not have packages for these accessories like ASUS fan control or AURA. I can live without the bling (I use coretemp with an addon and openRGB to set the LED colors to reflect cpu temp). Is there a way to monitor gpu temp and adjust pwm voltage of a fan header accordingly?
