Can't figure out why truck is overheating

What is your question?

My truck is overheating and I have replaced the radiator,water pump,fan and fan clutch,unclogged the burning up catalic converters and it's still overheating,it runs strong,there's no loss of compression so I can't figure out why it's overheating,no leaks or noises,just overheating

What makes this problem better or worse?

It’s always the same
