[SOLVED] can't control front fans speed

[Mockss]

context - today i moved my setup into a new case ( corsair icue 220t rgb airflow) im up and running all good but my front fans are clearly running full speed and i have no way of changing them. in bios i have option of cpu fan , system fan 2 and 1 , 1 is my back fan but 2 which in my old case would change the front ones says 0 rpm. the actual fans are connected into a fan splitter directly into power supply splitter? something like that but from what i see its nowhere into the motherboard. somewhere i read said this means they auto run full speed but it was the same on my old fans?
any advice would be nice.
my mobo is a b450m gaming

If your fans are plugged directly to your PSU then you can’t control them. You need to plug to motherboard Or get a fan controller.
