High-speed 120 mm PWM case fan

The BGears b-BlasterPWM 120 is a single 120 mm case fan built around a dual-ball bearing and a four-pin PWM controller. It targets builders who need a wide, software-controlled speed range for chassis intake or exhaust. The 25 mm frame fits standard mounting points.

Airflow capacity and pressure headroom

At full speed the fan moves 203 CFM and develops up to 13.0 mmH₂O static pressure, giving strong push-through for restrictive radiators or dense mesh. At the 1000 RPM floor it delivers only 21.5 CFM and 1.7 mmH₂O, so silent operation sacrifices most cooling capacity. The 14.4 W motor draws 1.2 A from the 12 V rail.

Dual-ball bearing and 5000 RPM ceiling

The two-ball bearing is the decisive spec: it tolerates the 5000 RPM top speed and continuous high-load duty better than sleeve or rifle alternatives, but it also produces more audible noise at mid-to-high RPM than fluid-dynamic bearings. Buyers who prioritise absolute silence over maximum airflow should look elsewhere.

Questions about this item

Will the 5000 RPM top speed overwhelm a motherboard header rated for 1 A?

The fan draws 1.2 A at 12 V, so a 1 A header would be exceeded; use a header rated for at least 1.2 A or a powered fan hub.

How can I confirm the 203 CFM airflow is being delivered after installation?

In the BIOS or fan-control software, set the PWM duty cycle to 100 % and verify the reported speed reaches 5000 RPM ±10 %.

Does the box include mounting screws or only the 120 mm fan itself?

The package contains the single 120 mm × 25 mm fan with a 4-pin PWM connector; mounting screws are not included and must be purchased separately.
