Driving it home it would overheat while idling. After doing some research I realized my car doesn't have a fan on the front of the engine.
It does have one on the front of the radiator which I assume is the aux fan. Is it necessary to have the engine fan?
Yes with a m50 swap its needed. A spal puller fan is a great option. However, you can work the aux fan using the AC switch (the one with the snow flake on it) inside your car. If you press the button and the fan does not come on, you will need to check the aux fan/wiring.

Note: The aux fan may not be enough.

What radiator are you using? M42?
