Radiator Fan

I just had a local machanic replace the alternator and belt tensioner about a week ago. Ever since then my radiator fan, which is electric, has been very loud like it is running at max speed almost constantly. I don't see the cars temp going above 85c, and I don't ever remember hearing the fan like I do now.

anyone have any ideas what to check?

Failing that, check back with your mechanic & have any necessary repairs done at his expense.

Thanks for the reply, I have checked the fan and it doesn't look damaged and spins freely. I'll have check around for the wires, and stop by the shop and let them have a look at it.
