Question Sys_fan2 not working

[DaFancy]

I just bought be quiet pure wings 2 and when i connect it to my motherboard (MSI B450M Gaming plus) into the sys_fan2 header, it wont work. When i turn on the computer it spins up for a second and then just stops.
Any suggestions are highly welcome.

Check that the SYS_FAN2 is set to PWM mode.

If you have BIOS v18 or older, update your motherboard to BIOS v19 or newer.
