I myself looked into this, I want to get away from using ICUE which is Corsairs RGB and Fan control and got trapped into its eco system having bought its fans what I noticed and others reported icue has background processes which use up I feel too much I even tested I closed all icue services and in idle power usage is around 15-20watts lower and even the CPU idle temps dropped as it was getting random spikes from ICUE
So started looking into using something else to control RGB (will get rid of the corsair fans) and control case fans according to GPU temps which I cant fault icue on very easy to setup curves etc
I have an MSI 570x unify board so downloaded MSI Center plugged 1 fan into sys fan header it doesnt let you set the curves according to GPU temps only for CPU
but can control RGB , So searched and found program called FanControl which seems to work well and its free
https://github.com/Rem0o/FanControl.Releases
computer uses less power also CPU idle temps dropped and less background processes being used
Now deciding what fans to go for the uni sl120 have caught my eye , Will just use MSI center to control RGB and Fan Control to set case fan curves
