I would also, if possible, compare the temperature as read via OBD with that displayed on the gauge (the OBD temp is the temp as read by the ECU).... The gauges on 156 have been known to be off.The temp doesn't go down with the fan running.. So I'm more inclined to think it goes opposite of what you're saying - that it maybe only runs on low speed.
I will check fan speeds later today.

Fans etc are controlled by the ECU, which uses a separate temp sensor. Gauge has it's own sensor.
