acpi fan does not lower speed when CPU temp is back to low

[Saulius Menkevicius]

Hi

Is there a way to find why the ACPI code does not lower
CPU fan speed when temperature drops back to low (as set in BIOS)?
It does turn the speed to 100% when temperature gets high.

Can it be a buggy BIOS ACPI? Though it's working fine in Windows.

The motherboard is Abit IS7, desktop with a P4 2.4C.
Running 5.3-BETA4.

Thanks.
