    My Model X makes a loud fan noise when it is exposed to direct sunlight in warm conditions (>25° C) when A/C is on. It is very loud from the outside, unusual for a car. During driving, it is not a problem for me inside the car, but the environment is exposed to a noise louder than that of a gasoline car, which is a bit unexpected for an EV.

    When cabin overheat protection is on, the fan switches on automatically every time the car is parked in direct sunlight after some time. The fan is also very loud in this condition, making so much noise that my neigbors are disturbed. That's why I switched off the overheat protection. Are you experiencing the same problem with the loud fan?

    What is your VIN? The early builds has switched lines that caused this noise

    Mine is 41XXX and it makes the same loud AC noise. Attracts a different kind of stare than the FWD. It's a feature man. ;) For those who aren't looking, we MAKE you look with noise.

    Loud fan here. Service specifically verified lines are ok.

    It's just the A/C throwing off heat to the outside using a radiator and a fan. My Porsche did the same thing. Sounded like a vacuum cleaner and kept the garage clear of stray leaves. My X is about the same. It's noisy without any other noise covering it up.

    One batch of Tesla A/C's were installed improperly and have to work much harder to cool down the car. That could be a cause of excessive noise.

    I usually get the loud fan noise for the first 30 seconds when turning the car on in the heat. After that it seems to settle down.

    The loud fan noise is normal as there is only one large cooling fan in the front of the Model X (as opposed to two smaller ones on the S).
