Fan FRACTAL DESIGN 120MM PRISMA AL-12 RGB PWM

FRACTAL DESIGN Prisma AL-12 RGB PWM is a 120 mm case fan that combines high airflow with addressable RGB lighting. It operates in a wide range of 500–2000 RPM, giving you flexibility – from quiet mode to serious cooling under load. At maximum, it provides up to 85.71 CFM of airflow and 2.78 mmH2O of pressure, sufficient for effective air exchange in gaming and work configurations. The black color and RGB backlighting make it a good choice if you want a clean internal look plus controlled lighting.

What you get

With a range of 500 to 2000 RPM, you can set the fan from nearly silent idle mode to aggressive cooling when the CPU and GPU heat up. The airflow of 85.71 CFM, combined with 2.78 mmH2O static pressure, is suitable for mounting as a front, rear, or top fan in a case, including through finer mesh filters. PWM control via the 4-pin connector allows the motherboard to dynamically control the RPM based on temperature, so you don't have to listen to unnecessary noise during light work. The Addressable RGB lighting at 12V / 5V allows you to synchronize effects with other RGB components, provided you have a compatible controller or motherboard. The LLS bearing and declared MTBF of 100,000 hours mean long life under 24/7 operation.

• Size 120 x 120 x 25 mm – standard form factor for most modern cases, easy to mount at the front, back, or top.
• RPM 500–2000 – wide range that allows for both quiet operation at low speeds and strong cooling under load.
• Airflow 85.71 CFM – provides serious airflow for effectively exhausting warm air from the case.
• Max. pressure 2.78 mmH2O – suitable for operation behind filters, grilles, and denser front panels, without losing much airflow.
• Noise level 32.7 dB(A) – balances noise and performance at maximum RPM, especially if controlled with a PWM profile.
• Addressable RGB lighting – allows individual control of effects and colors through a compatible RGB controller or software.
• LLS bearing and MTBF 100,000 hours – ensure long operational life, even under more intensive use.

Who it is suitable for

This fan is suitable for gaming and enthusiast configurations where you seek a combination of stable cooling and RGB aesthetics. It is suitable for upgrading a case with weak stock fans or for building a new build with an emphasis on airflow. If you are aiming for an absolutely silent system and will keep the fan constantly at low speeds, its potential at 2000 RPM may remain unused.

With a good combination of airflow, pressure, PWM control, and addressable RGB, FRACTAL DESIGN Prisma AL-12 RGB PWM is a practical choice if you want reliable cooling and a tidy, illuminated interior of the case.
