Is my cooler not the original?

I have a processor Intel Core Duo E6300@1.8Ghz Socket Lga 775, and I saw that the cooler is a Cooler Master [link]http://www.coolermaster.com.br/html/product.php?prod=302[/link], I think its not the original coz this is a Cooler Master, and not a Intel.
Someone has this processor and could help to say what cooler is?
There is difference between OEM and BOX processor? I dont know one of them doesnt have cooler! :-?
I'm asking it, coz my processor stays in 50
