Had this problem for a while now really, with my temp gauge not really working right, going right to the end, and only sitting in middle when it should if im going around 50/60 mph.
But when sat in traffic for a long time my fan doesnt kick in, not really had a problem before as i don't have to sit in much traffic for too long, but last night at southend was in traffic for a good 20 minutes, and my water ended up boiling over.
I know theres a sensor on the side of the rad, and one going into fan, so gunna clean em up and see what happens, would it be a good idea to spray some wd40 on it??
Or could it just be the fact my fan is knackered?

connect the fan directly to thebattery to see if it works, then you can see if its the fan or the thermostat thats gone.

Could it be this? It's missing it's clip where it clips onto the actual sensor which then clicks into the rad.
Thought it could be this as it's loose, so will tape it up and see if it changes anything. Gave the senor a clean and the fan sensor a clean too. So will see how it goes

That picture looks like the plug that goes into the fan switch on the side of the radiator.
If you bridge the 2 pins on the plug that go into the side of the radiator then the fan should turn on. If so replace the fan switch. Less than a fiver 
If the fan isn't coming on and your overheating its the best place to start!
