Radiator fan runs at high speed within five to ten seconds after I start the car and stops after about twenty to thirty solid seconds and goes back to normal (I presume only because my temperature is normal).

PS: This is every time I start the car.

Please help I’m young and still learning.

If the A/C is on when you start the vehicle up then most likely it is normal. If it is not then the cooling fan module is starting to fail. I believe the module is part of the cooling fan assembly. As it gets worse you may have a condition where it stays on all the time at high speed even with the engine off causing the battery to drain.
