Engine fan wont turn off

I'm not really arguing, but I didn't see where the tuning issue came from with an engine fan not turning off. Honestly, you can still blow a head gasket with perfect tuning. I'm not concerned about it at the moment, as the guy that tuned this one, tunes the trucks for his own fleet and they all seem to be running good too. I have no issues with it whatsoever.
