How to set cooling fans speed using IPMI? [duplicate]

Solution 1:

The last BIOS update for this serie allow a much better control from inside the BIOS.
Nothing is changed from the OS point of view, so you won't have more ability from IPMI or so.

To be clear: I don't know how to use IPMI from command line, so I don't know if it is possible to change fan speed.
