Chassis is SC846-R1200B. I replaced all 5 fans with Arctic F8 PWM (AFACO-080P0-GBA01). The Arctic fans have a 4pin PWM plug and the fans end up looking like shown in this post - My (near) silent SC847
The fans are all plugged into the MB header and not into the backplane. This is what I used to see before -
However now in the bios there's a brief message like - 'System fan control disabled, not enough fans detected' and in the 'health monitor' in bios no fan speeds are shown. Since I'm using PWM fans why is this happening? The fans all power on so I know the connection is made.
