Like i said earlier, my black base coupe's fan started a faint little squeak everytime the cooling fan came on and it started getting louder the noise. Eventually the fan seized on me in the middle of highway traffic and the car overheated. They replaced the fan and it took about 20 minutes. After i lemon'd that car, my replacement XFire started doing the same thing and before the fan seized, i quickly took it to the same service advisor of the black coupe. He replaced the fan as a preventive measure to not have the same thing happen. It's been working fine since with no squeaks.

Its the fan control module that fails and the fan wont come on.
