I've noticed that my GPU temperatures were getting significantly higher than they usually are and that my CLC 280 fans are quiet. Putting two and two together lead to find out that I can no longer control the radiator fan speeds and they don't follow the curve either. They are stuck around 1080-1020 rpm. I thought this may have been due to me putting my computer to sleep multiple times because that sometimes messes with Flow Control, but I restarted and still have the same problem. I've reinstalled Flow Control multiple times and it will not work anymore. I've never had a problem controlling the fans until now. The cable is connected to CPU_PUMP on my MSI motherboard.
