Why is my car overheating?
I left out some prudent information in my last details so here it is refined.
My thermostat opens at the correct temp. It's brand new.
My cooling fans kick on at operating temperature, my coolant temp sensor is fairly new as well.
My radiator is clean through and threw. It's 6 months old and has only had 50/50 mix in it.
My water pump still pumps and doesn't leak and sounds fine.
No air pockets are in my cooling system, coolant cycles through it properly it just overheats and water boils into my reservoir. My radiator cap is brand new and works at the correct pressure.
There are NO leaks. I'm not loosing coolant.

sounds like you have done everything possible,so I have to wonder if you have a blown head gasket,check the colour of your engine oil and water, if the water looks sludgy, and your oil is discoloured,,then this will lead to more problems starting it in time

Head gasket blown, or cracked cylinder head. The water boiling into the header tank is due to cylinder compression. ie: there is a crack, or the gasket is blown, between the cylinder(s) and the coolant galleries. Head needs to come off. If it's the gasket, then you should be able to see where the leak is. If its the head, then this could be less apparent, as the crack could be 'internal' – for example between a water gallery and exhaust port – hence the overpressurisation of the cooling system. A cracked block is also a very, very, remote possibility.

I'm afraid I only speak English, and you don't, so it's difficult.
How have you measured the temperature that the thermostat opens at? Ditto the cooling fan?
clean through and threw?
How have you checked the flow rate of the water pump?
How full do you fill the header tank?
