Single Internal Fan: The PS4 Fat 1000 1100 typically includes a single internal cooling fan, positioned near the rear of the console. This fan is responsible for drawing cool air into the console and expelling hot air out through ventilation grilles.

Variable Speed Operation: Similar to other PS4 models, the cooling fan in the PS4 Fat 1000 1100 operates at variable speeds. The fan adjusts its RPM (revolutions per minute) based on factors such as system load and internal temperature. During heavy gaming sessions or demanding tasks, the fan may spin faster to increase airflow and dissipate heat more effectively.
