Fractal Design Prisma AL-14 – The Silent Powerhouse for High‑Performance Cooling

The Fractal Design Prisma AL-14 is engineered to deliver exceptional cooling while maintaining a whisper‑quiet profile. With its 140 mm diameter, seven‑blade design and advanced Long Life Sleeve (LLS) bearings, this fan strikes the perfect balance between airflow, static pressure, and longevity.

Key Performance Metrics

  • Airflow: 31.67 – 103.85 CFM – ideal for both low‑noise setups and demanding overclocking scenarios.
  • Maximum Static Pressure: 2.38 mmH₂O – ensures efficient airflow through restrictive radiators or dense case filters.
  • Speed Range: 500 – 1700 RPM – adjustable via PWM for precise control over noise and cooling.
  • Sound Level: 15.1 – 34.1 dBA – remains quiet even at full speed, thanks to optimized blade geometry and bearing design.
  • MTBF: 100,000 Hours – guarantees reliability over the lifespan of a high‑end PC build.

Design & Build Quality

The fan’s 25 mm depth and lightweight construction (200 g) make it an excellent fit for tight case configurations. Its screw fixing system, complete with included screws, allows for secure mounting on any standard 140 mm chassis or radiator.

The Prisma AL-14 features a sleek, semi‑transparent housing that showcases the integrated LED lighting while protecting the internal components from dust and debris.

Advanced Lighting: Six Addressable RGB LEDs

  • ARGB Control: Fully addressable RGB allows for dynamic lighting effects synchronized with popular motherboard ecosystems such as Asus Aura, Gigabyte Fusion, MSI Mystic Light, and ASRock Polychrome.
  • Color Range: Multi‑color illumination provides vibrant hues that can be customized via software or hardware controls.
  • LED Voltage: 5 V – compatible with standard ARGB headers found on modern motherboards.

PWM & Connectivity

The fan includes a single 4‑pin PWM connector, enabling precise speed regulation directly from the motherboard or an external controller. The 500 mm cable length offers ample reach for most case layouts, ensuring clean cable management.

Optimized for Silent Computing

By combining LLS bearings with a low‑friction blade design, the Prisma AL-14 achieves a noise floor as low as 15.1 dBA at idle speeds. Even when pushed to its maximum 1700 RPM, it remains below 34.1 dBA, making it suitable for quiet workstations, home theaters, and gaming rigs that demand both performance and silence.

Versatility Across Platforms

The fan’s universal 12 V power rating and standard 4‑pin connector make it compatible with a wide range of motherboards and chassis. Whether you’re building a compact mini‑ITX system or a full‑tower enthusiast rig, the Prisma AL-14 adapts seamlessly.

Installation & Compatibility

  • Dimensions: 140 × 140 × 25 mm – fits standard 140 mm mounting points on cases and radiators.
  • Screw Fixing: Included screws ensure a secure fit without the need for additional hardware.
  • Cable Length: 500 mm – provides flexibility in cable routing, reducing clutter inside the case.

Why Choose the Prisma AL-14?

For users who demand high airflow and static pressure without compromising on noise levels, the Fractal Design Prisma AL-14 stands out as a top choice. Its combination of LLS bearings, PWM control, and vibrant ARGB lighting makes it a versatile component that enhances both performance and aesthetics.

Whether you’re building a silent workstation, an overclocked gaming machine, or a media center, the Fractal Design Prisma AL-14 delivers reliable cooling, customizable illumination, and quiet operation in one compact package.
