Is there a way to edit fan parameters on Dell BIOS?

[inimigor]

I have a Dell Optiplex 380 with a Xeon E5450, and I put a noctua fan on it, but since it slots down A LOT when under low usage, the PC usually shows a warning that a Fan Failure has happened, but I know it's nothing serious because the fan runs at a much lower speed.

I'd like to find a way to remove this warning, or at least relax the paramateres enough for it to not be a problem with the fan speed.

I've been a bit of a lurker for a while, but never really created an account, then created it and continued lurking
