are you sure the fan doesn't turn on? What kind of temperatures have
you been seing? As Karol noted, the fan isn't controlled the way the
spec intends (which would require implementing n fan devices for an
n-level fan, I think). Instead, TCHG is called every time the
temperature changes, which sets the fan speed directly based on some
threshold temperatures which vary based on cooling mode
(active/passive). That's the only place you can take influence wihtout
modifying the DSDT, though changing the mode to passive will increase
the thresholds. IIRC, these temperatures are quite high, though I don't
remember exact values. In the region of 70°C, for the lowest, I think.

Cheers
Robert
