+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the TDA8444 DAC used to control the fan speeds
+in Sun Blade 1000 and Blade 2000 systems.
+The speed of the CPU fan and of the system fan are automatically adjusted
+every 20 seconds, based on the currently reported CPU and system
+temperatures, respectively.
+.Pp
+The speed-related values are made available through the
+.Xr envstat 8
+interface.
+The range of the values are:
+.Bl -column -offset indent ".Sy System temperature" ".Sy Minimum" ".Sy Maximum"
+.It Sy  Ta Sy Minimum Sy Maximum
+.It Li CPU temperature Ta <=57 Ta >=67
+.It Li System temperature Ta <=20 Ta >=30
+.It Li Speed value Ta 12 Ta 63
+.El
+.Sh SEE ALSO
+.Xr admtemp 4 ,
+.Xr envstat 8
+.Sh BUGS
+The temperatures are reported as
+.Sq internal
+and
+.Sq external
+instead of
+.Sq system
+and
+.Sq CPU ,
+respectively.
