120mm 2000 RPM case fan

The BGears b-Blaster 120 is a 120mm case fan built for desktop cooling. It uses a dual ball-bearing design rated for extended life at high speed. The three-pin connector provides a speed signal to the motherboard. A 3-to-4-pin Molex adapter is included for direct power-supply connection.

Airflow and noise at 2000 RPM

At 2000 RPM the fan moves up to 103 CFM of air while producing 35 dBA of noise. That airflow level handles typical chassis exhaust or CPU heatsink duties. The fixed 2000 RPM speed means output does not scale down for quieter operation. Systems that need variable speed or silent idle will not be served by this model.

Upgrade from sleeve-bearing or lower-CFM fans

The dual ball bearing replaces sleeve-bearing fans that tend to wear faster at high RPM. The 103 CFM rating replaces lower-airflow 120mm fans when more heat must be moved. The jump is worth it when the build can tolerate 35 dBA and does not require PWM control.

Questions about this item

Will the 120mm 2000 RPM fan fit alongside older 120mm mounts in my case?

Yes, it uses the standard 120mm frame with 25mm thickness, so it aligns with existing mounting holes for 120mm fans.

How can I confirm the fan is running at its rated 2000 RPM after installation?

Connect the 3-pin header to the motherboard and monitor the RPM reading in BIOS or fan-control software; it should report close to 2000 RPM under full voltage.

Does the box include the 3-to-4-pin Molex adapter or must I buy it separately?

The 3-to-4-pin Molex adapter is included, allowing direct connection to a power supply without a separate purchase.
