Fan set FRACTAL DESIGN 120M PRISM AL-12 RGB PWM 3P

This Fractal Design Prism AL-12 RGB PWM kit gives you three 120 mm case fans aimed at mid-range to more serious gaming and work configurations. They combine high airflow of 85.71 CFM with PWM control via a 4-pin connector, allowing you to easily balance between cooling and noise depending on the load. The addressable RGB lighting allows you to synchronize them with other components and arrange the look of the case as you like. The black housing and standard thickness of 25 mm make them compatible with most cases and radiators, as long as you have space for 120 mm fans.

What you get

With a range of 500–2000 RPM, the fans can run almost idle during light work and ramp up serious airflow during gaming or rendering. The maximum static pressure of 2.78 mmH2O is sufficient for mounting even on denser filters or front panels with fewer openings, without “choking” the airflow. The noise level up to 32.7 dB(A) is a reasonable compromise for such RPM and flow – they won’t be silent at maximum, but they won’t “buzz” constantly if you set the PWM curve correctly. The LLS bearing and declared MTBF 100,000 hours are a sign of long life during 24/7 operation, especially if your machine is constantly on for gaming, streaming, or torrents. The consumption of 2.16W per fan is light for any modern system and won’t overload the power supply.

• Three fans in the kit – 3 x 120 x 120 x 25 mm, sufficient to fill the air intake/exhaust in most mid-tower cases.
• Wide speed range from 500 to 2000 RPM, giving you flexibility between quiet mode and aggressive cooling.
• Airflow up to 85.71 CFM, suitable for strong ventilation of the case with powerful GPUs and CPUs.
• Static pressure 2.78 mmH2O, which helps when mounting behind filters, dense panels, or thicker radiators.
• Maximum noise level 32.7 dB(A), easily controlled via PWM profiles depending on the load.
• LLS bearing with MTBF 100,000 hours, ensuring long life and lower risk of rattling and vibrations over time.
• Addressable RGB lighting at 12V / 5V, for synchronization with the motherboard and other RGB components.

Who it is suitable for

This kit is suitable if you want to create a well-ventilated gaming or work PC with controllable noise and organized RGB aesthetics. It is also suitable for warmer configurations with powerful GPUs, where serious airflow is needed. If you are aiming for an absolutely silent system and want the fans to be inaudible even under load, you might consider a model optimized entirely for low RPM.

The most sensible thing here is the combination of three 120 mm fans with high CFM, PWM control, and long life, plus addressable RGB, so you can cover both cooling and aesthetics of the case with one kit.
