Anyone know what the below is?

Obvious guess is an adjustable fan switch......

Rainbow is a Korean thermostatic switch manufacturer

You want to have it set to cut in about at least 8 to 9 degrees above the thermostat temperature and cut out at least 4 degrees above or the fan
will run continuously.
Cheers all, that makes sense tbh. Temperature runs perfectly and it has a nice overrun on the fan when i turn it off so im just going to leave it as
it is 
If thats temp in centigrade that it comes on at (and is accurate) it must be running nearly all the time. You might want to turn it up. The fan
shouldn't need to be on unless you're stationary/in traffic, as long as the cooling system is adequate. If I leave mine running by mistake
(got a manual override) when moving the temp actually goes higher (assume the fan is disturbing the air flow). I'd turn it up and see how the
temp copes when driving, then adjust it so it comes on as they rise when stationary. Fans normally come on around +90c.
Or it could be the sensor for your gayness gauge

You now know what it does
If it ain't broke etc,
Really bad idea to have it set at too low a temperature..
The fan running on after the engine is stopped has no value except for cars with turbo chargers or air-conditioning.
The lower engine coolant temperature range is determine by the thermostat, if thermostat is closed the fan running is cooling the radiator not the
engine. Modern engines (anything built since 1965) run the coolant in 88 to 105c range the oil should run within 10 degrees of the oil temperature.
