Please do not forget to CLICK ON a positive rating.
the fan runs at full speed when there is a cooling system fault, this is expected and does not reveal anything specific
there are MANY possible causes of an overheat, the most likely in your situation are:
cooling system not properly bled after repairs
water pump defective
faulty thermostat
blown head gasket
blockage / restriction
