I am using Argus monitor on my Prime Z270-A. No problems whatsoever - the only software which allows to properly control some fans by maximum(GPU, CPU) temps and smooth out Kaby Lake temperature spikes (because fan delays in ASUS BIOS are rubbish.

Its just an arbitrary restriction by Asus, same as limiting curves to 75 degrees top. Here they've decided AIO header should be only controlled by CPU.It's not a hardware restriction - header itself is perfectly capable of controlling itself with any...
