Thanks for your reply

I do have 2 fans atm one for AC and one for thermo, i have been using the AC to test it out as i just bought the car and the AC fan fixes the issue i'm talking about but i dont want to have to turn on the AC when the car is getting warm. I also think the system above is a brand i have not heard of but what about this system:

I've heard this brand name before.
It only takes moments for the fan to do its job once it is turned on which leads me to believe that the radiator is fine but i still might follow your suggestion to get it looked at.
