If your radiator fan is electric, loss of electrical power can cause it to stop working such as a break in one of the wires. There can also be a fault in the speed controller thermostat that is not signaling the fan to turn on. If the fan won't move at all and cannot be manually tuned, the internal bearing may have failed.
If your radiator fan is mechanically attached to the engine, the fan clutch can be faulty and not engage.

What could cause smoke coming from the Radiator Fan?
If the smoke is coming from the electric fan itself, then it needs replacing. It could be the smoke is steam that the fan is drawing from the radiator, and you have a coolant leak at the radiator.
Could a fuse cause overheating?
No, if a fuse were to overheat it would blow. A shorted circuit can cause a fuse to blow. Yes. If the fuse for the electric cooling fan should blow, then the fan will not turn on and remove heat from the radiator at low speeds. At higher speeds, there will be enough air movement to cool the radiator. Also if your experiencing problems with your car overheating you should look into other causes, such as making sure your anti freeze reservoir is full
