Not all 80mm fans have PWM control. PWM (Pulse Width Modulation) allows for automatic speed adjustment based on temperature, providing efficient cooling. Check the fan specifications for this feature if you want dynamic speed control.

Can 80mm fans be used for both intake and exhaust?

Yes, 80mm fans can be used for both intake (bringing cool air into the case) and exhaust (expelling hot air out). The direction of airflow depends on how you mount the fan in your case.

How long do 80mm case fans typically last?

The lifespan varies based on build quality and usage. Generally, a good quality 80mm fan can last from 30,000 to over 150,000 hours. Fans with high-quality bearings and solid construction tend to last longer.
