Had some trouble installing the AL120s on the AIO but there was a tutorial and it helped me in the end lol.
As soon as I booted the pc with the AIO, fans were running at full speed and had to turn on PWM in the BIOS and it fixed the issue.
Yes, there isnt any consistency in the fans brands in this build but it doesnt bother me. I'll change if I feel the need to later on.
