PHONE COOLER CHROMA Profile Quiet

Hi, it seems the profiles * Auto * Standard * High have little to no difference in RPM. I am looking for a function to manually adjust fan speed for given temperature. Is that possible to implement..? Alternatively a Fan Speed setting named * Quiet would be helpful too, because the noise is uncontrollable and uneasy Sone. I tried decompiling and looking into the apk source, I found some settings however they are quite complex, for what the cooler actually regulates..
