I think the thermofan only runs to supplement the regular cooling, and there fore only comes on when needed. Could be wrong.
On my track car I just removed it and taped up the hole and my water temps are fine. Oil temps are still high though.
I would check your coolant level again, as sometimes you get an air lock causing you to think it is full.
Also get some toyota red anti freeze/anti boil in there to as well.
I have never boiled my coolant, so there may be an issue. Some other things to do: 1. check you have all the undertrays- these aid cooling and aero. 2. get your radiator reconditioned. Mine cost about $200 at NATRAD and came back looking brand new. I have never had an issue in the track car since. 3. Install an oil cooler if you are going to do more track work. Higher oil temps leads to higher coolant temps. You turbos will last longer too. 4. Check the condition of the cooling system (fan, thermostat,etc.)

It could be the under trays, air is diving under car rather than passing through rad ,the front tray has small scoops to keep the pressure high in front of rad.
