Blæser Noiseblocker B12X-PS-BL

The Noiseblocker B12X-PS-BL is a 120 mm case fan combining advanced Noiseblocker eLoop blade technology with programmable ARGB lighting and an energy-efficient hub design. It is engineered for PC builders and modders who need reliable airflow and enhanced static pressure for radiators and water-cooling applications while maintaining low noise levels. The compact 120 mm x 25 mm profile and black finish suit a wide range of system layouts.

Advantages

The fan offers bionic eLoop blades for improved airflow and reduced turbulence, a semi-passive option for near-silent idle operation, and enhanced static pressure to improve cooling on radiators and heatsinks. Integrated programmable ARGB LEDs with energy-saving hub lighting provide customizable accent lighting compatible with common motherboard ARGB headers and controllers. The unit is lightweight (0.125 kg) and optimized for efficient cooling at 5 V operation.

Suitable for

• PC cases requiring a 120 mm fan
• Water-cooling radiators and closed-loop coolers
• Gaming rigs and custom PC builds with ARGB lighting
• Quiet workstation and home PC systems

How to use

Install the fan in a compatible 120 mm mounting location using the supplied screws or vibration-damping mounts if provided. Connect the power and ARGB LED cables to the appropriate 5 V fan header and 5 V ARGB header on the motherboard or to a compatible controller, observing correct pin alignment. Configure fan speed and ARGB lighting through your motherboard software or ARGB controller. For best results, orient the fan so airflow direction matches your case ventilation scheme.

Recommendations

Use the semi-passive option when low-noise operation is preferred; enable higher RPM or configure a fan curve under load to maximize cooling for demanding applications. Ensure ARGB connections match your controller voltage (5 V) to avoid compatibility issues.
