Mercedes C63 Engine cooling fan running on high

I recently bought a 2009 C63 that had a minor accident on the front end. I replaced the condensor and fan, and upon turning the keys to on the engine fan started on high before I even started the car. The AC and everything else was off in the car.

I checked all fuses that could relate to fan as well as tested with another engine fan and it does the sane exact thing. At this point Im really not sure what might be causing the fan to keep running on high right away. Any feedback is appreciated.

What is the climate temperature?

I park in a closed garage where it gets little air flow and temperature gets really hot (above 33 celsius) and humid. And the fan turn max , specially when the car had not fully cool down.
