M30B35 fan setup?

(I'll post this in technical help also as more folks will see it.!)

Just got a completed M30 project car, nicely done everything working as it should, fast.!

Only issue is the fan setup, its currently controlled via an on/off switch on the dash, I keep having to turn it on when the car temp is in the middle, then off when it drops to a quarter. Very annoying, I'm afraid I'll forget and it will overheat.

Is there anyway I can get some kind of temperature controlled switch that turns the electric fan on when the water reaches a certain level and turns off when its too cool? My wifes e46 318i has a setup like this.

The radiator has a fitting for a temperature sensor could I use this? If anyone could point me in the right direction to a kit or parts it'd be much appreciated.!
