Anyone running lower temp fan switch on TE310?

So my fan kicks on at about 190F like it’s supposed to, however my clutch starts dragging at like 180-185F. 190 seems super high to me. In a car that’s encroaching on overheating/warped head territory. Has anyone fitted a lower temp sensor to have the fan kick on earlier?

My fan never starts. Might be because I live in north of Sweden . First time I heard the fan was when I ended a race a really hot summer. I looked at it and thought, ”HEY you are working after all” .

If you have the Mikuni EFI the ECU turns on the fan based on coolant temp; there isn't a separate fan switch. It could probably be retrofitted with some kind of add-on temp switch, but you wouldhave to find a place to put the new sensor.

I have not been able to find a setpoint for thr fan embedded in the ECU that could be used to adjust the fan setpoint.

FYI, if you unplug the sensor, the fan kicks on. Other than controlling the fan, I have not seen that the coolant temp sensor effects EFI operation. It will throw a fault code that will clear when the sensor is replaced.

If your 310 is a 2013 redhead you can always put a switch on the thermostat and manually control the fan whenever you deem it necessary without waiting for it to turn on by itself
