Wow! Didn't expect so many quick replies!

SpeedFan not an option?
If it was for my own use SpeedFan would be fine, but for this person I'm trying to keep things as simple as possible.
In reality once I finish setting everything up I doubt owner will ever to anything beyone just using it. Probably won't even clean filters.

That way the mainboard checks at what PWM strength/DC voltage your fans start to spin.
Yes, both in windows and in BIOS.

Asus software regarding fan control its an insult to trash.
Use low noise adapters. The only thing i can come up with.....
It's what they got for me to setup, so can't change things. If I had low-noise adaptors I would give them a try, but I don't

I just looked at the manual, and it shows that Min Duty Cycle on the fans can only be set to a value of 60-100%. That is freaking absurd.
If you have one of the Phanteks hubs laying around, switch the header to PWM and use that. That may solve the issue.....the issue that shouldn't have existed in the first place. 60% minimum????
I missed that in manual .. and searching online. Mobo software does set PWM below 60%. Cooler PWM fan is spinning very slow and silent.
I tried one Phanteks PWM hub with 2x fans with same results. I'm going to try it again with all 4 case fans on it and see if that gets speeds down. Only think I like about this board is fan stop. Expecting users to run fans at speed over 60% defies all logic.
Forcing them to do so means I'll never buy another Asus motherboard.
Edit: Found below link, but when I tried it even in BIOS fan speed was still locked at >60%. Maybe I'll give it another try.
