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.
