No coil whine but noisy fan

The Supernova series seem to handle coil whine quite well which was the main reason for getting the G3.

Confirmed there is no coil whine with the Asus Ranger VIII motherboard and MSI 1070 Gaming X, this unit is solid.
However, than fan is noisier than any other fan in my system, even at medium load.
The fan will not spin under 20% load but once it goes over this, the fan spins up quite fast, assuming in an effort to move hot air quickly before it starts settling down. The other problem is that this happens too quickly and too often. At a power draw of around 200W (30%) the fan would keep spinning up every 20 minutes or so (ambient temp of 23c) This is quite an aggressive fan curve and would have been far less intrusive if the fan just spun more constantly at a lower RPM.

My system is relatively quiet so this was unacceptable, especially for a PSU that's being advertised as "whisper silent"

I've since bought the Corsair RM750i, granted it's a stronger unit, the fan is still super quiet at it's lowest RPM and I can't hear it unless my ear is right against the unit.
