@SaintStefan the ramping fans is a thing that has existed in laptops forever. My former CAD laptop had this issue, so does my current employer HP laptop and my new GL703GS. The best fan solution i've ever had was with my old G751JY laptop which has a constant low hum and a gentle fan ramp.
I'm not really expecting ASUS to release any sort of a fix for this, it's a design feature. the only thing i hope is that we would have the ability to permanently undervolt CPU and GPU in bios instead of having to rely on extra software running constantly in the background. GL703GS is almost half the thickness of G751JY and thus has to push more rpm to move the same amount of air.
I think after the quiet years of my 751, it's time to move back to using more headphones....
