Bgears b-BlasterPWM 120x38 mm 2 ball bearing PWM fan with speed range from 1300 to 6500 RPM AirFlow 318 CFM 4pin 4wire PWM 12VDC fan.

The Bgears b-BlasterPWM 120x38mm is an extreme-performance PWM case fan designed for intensive cooling applications, featuring a thick 38mm frame and dual Japanese ball bearings for enhanced durability, high-speed stability, and extended lifespan under demanding conditions. With a 4-pin PWM connector, it offers precise motherboard-controlled speed adjustment ranging from 1300 to 6500 RPM (±10%), delivering massive airflow up to 318 CFM and strong static pressure for pushing air through dense radiators, heatsinks, or restricted case intakes. Operating at 12VDC with a power draw of approximately 30W at maximum speed, this fan excels in high-heat scenarios such as overclocked systems or mining rigs.



Engineered with a robust motor and optimized blade design, the b-BlasterPWM 120x38mm prioritizes raw airflow and pressure over low noise, making it ideal for users requiring maximum thermal dissipation in server-grade or heavy-duty PC builds. The dual ball bearing construction ensures reliable operation at elevated RPMs, while UL, CE, FCC, RoHS, and REACH certifications confirm compliance with safety and environmental standards.

Compatible with standard 120mm mounting points, the fan includes four mounting screws for straightforward installation in cases, radiators, or custom cooling setups. PWM functionality allows dynamic speed scaling based on temperature, balancing performance during load while reducing RPM (and noise) at idle.

Suited for enthusiasts and professionals seeking uncompromising cooling power in compact yet high-output configurations, the Bgears b-BlasterPWM 120x38mm stands out as a heavy-duty solution for extreme airflow demands where silence is secondary to thermal efficiency.
