What temperature does the fan kick in ? I have an 70 or 75 degree switch and the fan was on constantly, so have changed it back to a higher one ! I am thinking of getting one of those variable switches.
Cooling when parked up / sat in traffic is when the temp starts going up and difficult to get back down, so this is useful knowledge. Any more ?
