A drop off to 0 rpm under 1185, that can't be right. It seems to only be giving you half the controllable range. The SP120 should do 1650 rpm max also, not 1106.
What is the H-AMP header? Have you tried putting them on individual fan headers and running fan tuning again?
as opposed to
I believe it is reading RPMs wrong as there are 3 fans connected, where as MSIs software was reading it correctly.
I want to use one header, because the three fans are at the bottom, and the sensor for the QFAN(chipset/PCH) is there.
If I use different headers, the will use different QFAN sensors and also run/ramp up & down at different speeds, and that can get really annoying..
Is this speaking to the same issue?
New version of ASUS AI Suite that works with KB4056892 availabe - Page 3 - Windows 10 Forums
I'm planning on buying the X Hero and 8700K also so have already downloaded the manual. It says something about disabling Q Fan features when connecting 3 pin DC fans to the H_AMP header, have you checked that? What does H_AMP stand for anyway?

High Amperage= for anything over 1 amp, which the other headers use.
Say you connect 2 or more fans to one "normal" header, and their power draw is more than 1 amp, that could burn out the header eventually. ie> .40 + .40 + .40 = 1.20 amps
Also there are some high powered monster fans out there too.
I think disabling QFAN will just run them at max speed.
There must be some reason why they recommend PWM fans on the H_AMP header or to disable Q Fan when running DC fans on that header. Maybe you will need clarification from Asus as to what that is all about...
I'm not exactly sure what they mean by disabling Q Fan features. Can Q Fan be disabled for a particular header only?
It could be some bug in the software or some quirk with the H-AMP header.
Have you tried support in the Asus forums? I'm not sure what else to suggest. It must be driving you crazy having those 3 fans running constantly at 1000 rpm+. Good luck!
Being I have tinnitus, at least the noise helps that
It just bugs me, a much more expensive ROG board, doesn't offer the granular DC fan control, I had on the cheaper(but still good) MSI PC MATE.
But other than that, I'm usually listening to music when on the PC, so don't really hear them.
