Disable BIOS error messages on Boot

I have a small number of Optiplex models that indicate the rear fan has failed when the PC is cold booted.

Having run full diagnostics on them via F5, the results show no issues with any of the hardware.

The fan does appear to be working but the machine will not boot until the user has pressed F1.

I have updated the BIOS to the latest revision available and also cleared the log but the message persists and stops the PC from booting.

Is there anyway to turn off these warnings so there is no need for user intervention?
