Fractal PRISM AL-18 RGB PWM 180mm Fan

Fractal PRISM AL-18 RGB PWM is a large 180 mm case fan aimed at more serious builds where you want a lot of air at lower speeds. With a size of 180 x 180 x 38 mm and PWM control, it allows fine tuning between silence and cooling according to needs. The airflow of 43.1 – 146.8 CFM and static pressure up to 2.50 mmH2O make it suitable for front intake in cases with limited openings or dense mesh panels. The added Addressable RGB lighting gives you visual control over the look of the entire build.

What you get: thanks to the range of 300 – 1200 RPM, you can run it almost silently for light idle and daily work, and under load, you can increase the speeds and achieve maximum 146.8 CFM for lower component temperatures. The noise level of 14.9 – 37.4 dB(A) means that at lower speeds, the fan remains almost unnoticeable, which is important for quiet or living room configurations. The LLS bearing is a good balance between long life and smoother operation, so you won't have to think about replacement soon. With a 4-pin PWM connector, you connect it directly to the motherboard or fan hub and let the BIOS or software manage the curves according to temperature. The separate 3-pin 5V ADD-RGB connector gives you synchronization with the motherboard for effects, scenes, and color profiles.

• Large format 180 mm fan provides high airflow at lower speeds compared to standard 120/140 mm.
• Range of 300 – 1200 RPM allows flexible balance between maximum cooling and quiet operation.
• Airflow of 43.1 – 146.8 CFM is suitable for cases with fewer intake openings or for highly ventilated front panels.
• Maximum static pressure up to 2.50 mmH2O helps air pass through mesh, filters, and denser front panels.
• Low noise level 14.9 – 37.4 dB(A) makes the fan suitable for quiet systems and gaming cases close to a workspace.
• LLS bearing provides longer life and smoother rotation compared to basic sleeve bearings.
• Addressable RGB with 3-pin 5V connector allows synchronized addressable effect with the rest of the RGB in the system.
• 4-pin PWM control gives precise speed control through the motherboard or controller.
• Classic black color that fits almost any build, from minimalist to full RGB.
• 24 months warranty gives you peace of mind for long-term use.

This fan is suitable if you are building a more serious case with space for 180 mm fans and want strong airflow without excessive noise. It is ideal for front intake in large gaming cases, for configurations with a powerful GPU and many drives, where heat quickly accumulates. If your case only supports 120 or 140 mm, this model simply will not fit physically, and you should check compatibility beforehand.

The most sensible aspect here is the combination of large 180 mm format, wide RPM range, and good airflow with addressable RGB, so you don't have to compromise between cooling, silence, and aesthetics. If you are looking for a serious intake fan for a large case, this Fractal is right in that niche.
