=head1 NAME
fanspeed - set fanspeed using IPMI
=head1 SYNOPSIS
B<fanspeed> I<degrees>C
B<fanspeed> I<percent>
B<fanspeed> bios
=head1 DESCRIPTION
B<fanspeed> will set the fanspeed using IPMI.
=head1 OPTIONS
=over 9
=item I<degrees>C
Run fans at 40% unless temperature goes above I<degrees>. When that
happens: Let BIOS control the fan for 30 seconds.
=item I<percent>
Run fans at I<percent> percent.
=item bios
Let BIOS control the fans.
=back
=head1 EXAMPLES
=head2 EXAMPLE:
Run fans at 40% unless temperature is above 60C. When temperature is
above 60C, let BIOS control fans.
fanspeed 60C
=head2 EXAMPLE: Run fans at 50%
fanspeed 50
=head2 EXAMPLE: Let BIOS control fans
fanspeed bios
