I've had this issue before with Samsung refrigerators. The sound of the fan is usually it hitting against an ice build-up, which means no air-circulation, which means no cooling. The best solution to try first is to do a complete defrost (unplug the fridge and leave the doors open for 72 hours, removing any ice build-up that you can see/find). This worked for my fridge.
