Hello, they made some bug on that recently update through Armoury Crate (AC) and it broken AiO fan control in AC. I can tell you to wait for the them to be fixed. Same thing happens to me with Ryujin but my fans stays the same, coz it works with bios and uefi controller and settings should be stored in system memory for AiO, so I can´t change fans but it stays the sma like before...Maybe coz of your new FW it has been set to factory defaults...
On the other hand I am able to control Ryujin 360 with AiSuite 3, why u don´t is mystery.... Does Ai3 works for you?
