Fans are required at the front of the car. Please be sure these are aimed at the radiators in the front bumper.
The 992 Turbo / Turbo S and 982 718 models contain air vents behind the door or on the rear wheel arch. Please insure that fans are blowing air into those vents to properly cool their systems.
992 Carrera and Turbo models have their intercoolers located in the center section of the rear decklid, so airflow directly to there may be difficult. Ideally, it's best to get fresh cool air to the top of the center of the rear decklid, but if this is not possible we recommend having a fan aimed from the bottom of the rear of the car upward. Be mindful not to be directly blowing hot exhaust gasses in the intercoolers as you will just be introducing hot air to the system.
