I have a 2005 Yukon that at idle overheats. I've changed out the water pump thermostat and check the radiator and make sure there's nothing clogging or blocking it. Fans are running fast, I have no idea where to go next, any help would be truly appreciated.

its an 05 so im going to assume it has a fan clutch ?
that would be my next step because even though the fan appears to be running if the fan clutch has never been changed chances are the fan clutch is worn out there usually good for about the life of the water pump
