Astralcooler Cooling Fan 120mm Black

Product Function

• To remove heat from the radiator:
  • A water cooling radiator is composed of dense metal fins and winding coolant passages. Without a fan, heat exchange on the fin surfaces depends mainly on natural convection, where sluggish airflow allows a "thermal boundary layer" to form, greatly hindering heat transfer. The fan’s high-speed blades create a directed airflow that forces air to sweep across the fins at high speed, constantly replacing warm air with cool air at ambient temperature. This dramatically lowers thermal resistance and enables efficient heat transfer.

Featured Design

• Balance of High Rotational Speed and Silent Design:
  • Even at speeds reaching several thousand RPM, the fan effectively suppresses wind noise and vibration through optimized blade aerodynamics and fluid dynamic bearing (FDB) or magnetic levitation bearing technology. Combined with intelligent PWM speed control, it dynamically adjusts the rotational speed based on load, keeping noise levels below 28 dBA while delivering powerful airflow.
    
• Ultra-High Static Pressure (≥300 Pa):
  
  • With a maximum static pressure exceeding 300 Pa, the fan can easily overcome the resistance of radiator fins, dust filters, or dense chassis grilles. It is particularly suitable for water cooling radiators, tower air coolers, or high-impedance chassis intake applications, ensuring that airflow "presses through" every cooling fin and avoiding airflow drop-off.
    
• High Airflow (≥80 CFM):
  
  • Delivering over 80 cubic feet of air per minute, the fan rapidly expels hot air accumulated inside the chassis or supplies ample fresh cool air to heat sources such as the CPU and GPU. The combination of high airflow and high static pressure significantly reduces chassis temperatures whether the fan is used as an intake or exhaust fan.
    
• Long-Life Bearing:
  
  • Utilizing dual ball bearings or advanced ceramic bearings, the fan offers excellent wear resistance and high-temperature tolerance. The MTBF (Mean Time Between Failures) can exceed 50,000 hours, allowing for stable operation for several years even under 24x7 continuous use. The sealed bearing structure effectively prevents dust ingress, further extending the service life and eliminating issues such as abnormal noise or speed degradation over time.

Premium Material

• The fan frame made of PVC composite material achieves an ideal balance between structural strength, vibration damping & noise reduction, and durability. This material is modified from traditional PVC by adding elastomers, toughening agents, or glass fibers, which not only enhances impact and bending resistance—ensuring the frame does not crack or screw holes strip under long-term high-speed operation—but also effectively absorbs blade vibration and reduces chassis resonance noise thanks to its high internal damping coefficient. Furthermore, the optimized formulation offers excellent heat resistance (dimensionally stable from -20°C to 80°C) and a flame retardancy rating of UL94 V-0. Even when used on radiators for extended periods, it resists aging and deformation, balancing safety with long service life.
