Deliver exceptional cooling performance with this 12cm high speed PC case fan. Engineered with a 4-pin PWM connector for precise speed control, it generates large air volume for efficient heat dissipation while maintaining quiet operation. This fan is an excellent choice for DIY enthusiasts and professionals seeking reliable cooling at an accessible price point. Features and Benefits
- 4-Pin PWM Control - Allows for automatic, motherboard-regulated speed adjustments from whisper-quiet to maximum airflow, balancing cooling and noise.
- High Static Pressure Design - Optimized blades and frame efficiently push air through dense heatsinks and radiator fins for superior thermal transfer.
- Large Air Volume - Moves a significant volume of air to rapidly exhaust hot air from your chassis, lowering overall system temperatures.
- Hydraulic Bearing - Provides smooth, durable, and quiet operation with a long service life, ideal for 24/7 use.
- Anti-Vibration Rubber Pads - Minimizes resonance and prevents vibration transfer to the case, reducing audible noise. Applications
- CPU Cooler & Radiator Upgrade - Directly replace stock fans on air coolers or AIO liquid cooling radiators for improved thermal performance and acoustics.
- Case Airflow Optimization - Install as intake or exhaust fans to establish positive air pressure and eliminate hot spots within desktop PC builds.
- Server & Workstation Cooling - Provides reliable, high-volume airflow for critical systems requiring consistent cooling under sustained loads.
- Silent PC Builds - The PWM functionality enables near-silent operation at low loads, making it suitable for home theater or office environments.
