I run a mechanical temp gauge (like a thermometer basically) and a thermostatic controller for the fan.
Not a big deal at all really but since they agree with each other on the temps it makes it kind of a verification that is nice.
The thermostat for the fan comes on at 210 according to the settings on it, and when the fan comes on the gauge says 210 on the nose.
There is no way you will do anything but guess until you can verify temps in degrees.
