I bought an MSI prebuild PC with a MPG Z590M GAMING EDGE WIFI mainboard and CPU water cooling which I assume is a MAG CORELIQUID 120R.

The water cooling had some issues (don't ask), so I replaced it with a regular air cooler. I connected that new cooler fan to the "CPU_FAN1" connector on the mainboard. The "PUMP_FAN1" connector which was previously used by the water cooler is now unused.

The system runs perfectly fine now, even under continuous heavy CPU load.

However, every time I start the PC, the BIOS greets me with a red warning text saying "Pump fan error, Please check". I would like that warning to go away.

I already tried these things in the BIOS settings:

  • "CPU Cooler Tuning": Switched from "Water Cooler" to "Tower Air Cooler" (screenshot). This didn't do anything.
  • Switched the "CPU Fan Fail Warning Control" toggle off (screenshot). That did the trick, but I don't feel very comfortable disabling that setting, because I assume it will then no longer warn me if my new CPU fan fails for whatever reason.

Is there a way to stop my BIOS from complaining about the missing PUMP fan without also disabling warnings about any other fans?
