Can you hear the fan clutch kick in when the engine is hot? Also, you can have a plugged radiator either internally or externally. On the outside chance you have a blown head gasket, but lets go over these guides which will tell us what is going on.

Please upload a short video in your response of the problem, so I can see what's going on
