I found that my radiator fan isn't working. What could have gone wrong? It was all fine until I noticed when temperature needle was going up and my radiator fan didn't turn on.

Check if whether your fan relay is properly working. Sometimes if wire to the fan relay is broken, then this issue comes up.

Most common reasons for a radiator fan not working will be a blown fuse, a bad relay, or a broken wire. It can also be caused by a faulty coolant temp sensor, low coolant level or the fan itself can be damaged. Your cooling fan is controlled by a thermoswitch on the radiator. It grounds out at around 95 degrees and completes the ground circuit to the fan. Note that the fan has power all the time from the ignition switch.
