Most the time the cause for an engine to run out of it's normal range is due to electronic sensor failure.
If your engine is not mixing the exact air to fuel this will cause operating temperature problems. If you have maintained the car well you should look into the sensors such s as knock, MAF, and oxygen.
If one of these is bad the engine could run lean which would cause extreme combustion tempts and frequent, fast, overheating.
Many times I have customers replace cooling system parts unnecessarily. Modern engines have a very small window of which they will run as designed without fault and passing emission standards.

Perhaps your airconditioning condensor fins are severely smashed, and therefore not allowing air to flow through the condensor and then through the radiator.

If ur radiator is good and u checked ur fans, they work, take off ur thermostat. run ur car with no thermostat and see what happens. if it overheats than take it to the shop.
