Welcome Kymco Owners!
Well if it is relay controlled it is either a sticking relay or bad sender. Find the temp sender, and disconnect it. That should stop the fan unless the relay is stuck closed. I would replace the OEM relay with a Bosch anyway. They are cheaper, and available everywhere. http://www.google.com/products/catalog?client=opera&rls=en&q=bosch+30a+relay&oe=utf-8&channel=suggest&um=1&ie=UTF-8&tbm=shop&cid=5981072858508301476&sa=X&ei=DUzJT9SpNYWE8ATjo534Dg&ved=0CKMBEPMCMAE
