Aux fan temp?

what temp does the aux fan come on at? i have a 87 TII. i'm asking because thats about where my temp likes to ride, right when the aux fan turns on.

I've had cooling problems befor and they tell me that 1/4 way up on the stock s4 gauge is OT (180degrees), but my aux comes on about 1/2 way up the gauge.

OEM thermostat starts opening at 177*f-182*f, fully open at 203*f.

Electric fan on at 207*f or when A/C operates.

It's all in the FSM.
