Phanteks M25 Gen2 140mm DRGB Reverse Airflow PWM Triple Fan Pack - Black

You can control fan speed through the PWM connection to your motherboard, using the BIOS settings or fan control software.

Ensure your case supports 140mm fans. Also, check for the clearance of the reverse airflow configuration.

You can use your motherboard's software (such as ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, etc.) or the Phanteks DRGB controller, if you have one.
