Bios overclocking and fan reading issues?

Do the fans support RPM output? Check if the fans have three wires (three should mean yes).

Good catch, Nailz!

Yes, the third wire provides the signal for reading the RPM.

I have the same problem happen. I attach RPM sensor fans and my BIOS displays the fan speeds as '0' still.

Does this problem occur for all fans?

Yep. Neither CPU fan displays RPM.
update: Flashing the RV bios seems to have made it work. And I needed it for ACPI power-off anyway.
