The 3D printed case is paired with a 4090 fan and can be connected to the motherboard via a PWM interface ^^ The thin size of 120x120x18mm can still bring up to 86.9CFM of air volume, suitable for use in small spaces and maintaining good heat dissipation ^^ The use of FDB bearings can bring a longer service life and can be adjusted up to 3300 rpm via PWM ^^ The fan blades adopt an integrated outer ring design, and the airflow noise will be reduced when the speed is lower than 1500 rpm. ^^ Includes two specifications of screws, which can be used for liquid cooler screws or Case
