The easiest is to restart the system and then press F2 repeatedly when the splash screen first appears.I did see ASUS AI suite 3 inside the armoury crate to download. I’ll give that a try.
How would I do this inside the bios? Is that an F2 press at boot up? @NoddyPirate
Once you are in your BIOS you will see Q-Fan at the bottom of the main screen:
Click on the QFan Control button there and it will take you into the Q Fan settings.
AI Suite 3 contains the Fan Expert facility - which is a good bit easier to use. There is an extremely remote chance I think that one of your fans might not be controllable from within there and a BIOS setting might need tweaking, but we can cross that bridge if we come to it - which I doubt we will!
This is what Fan Expert looks like - when you open AI Suite 3, select the three lines on the left margin to find it.
