High-Airflow 120 mm 38 mm Case Fan

The BGears b-Blaster 120x38 is a 120 mm square frame fan with a 38 mm thickness. It uses a dual ball bearing and spins at 4500 RPM to deliver 218 CFM of airflow. The unit connects via a standard 3 pin header and includes four mounting screws.

Suited for High Static Pressure Needs

This fan targets builders who need maximum airflow through restrictive CPU heatsinks, dense radiators or chassis with limited intake paths. The 45 dBA noise level at full speed makes it a poor choice for quiet-focused workstations or silent living-room PCs.

Critical Spec 38 mm Thickness

The 38 mm depth is the single dimension that decides fitment. Verify that your case fan mounts, CPU cooler shroud or power-supply cavity can accept a 38 mm thick frame before ordering.

Questions about this item

How much air does 218 CFM actually move through a case?

At 4500 RPM the fan pushes 218 CFM, delivering very high volume through a 120 mm frame; expect strong cooling for dense heatsinks or restricted chassis layouts.

What does the 3‑pin connector limit for speed control?

The 3‑pin header supplies 12 VDC and a tachometer signal; voltage‑based regulation works, but PWM duty‑cycle control is not supported.

Will the 38 mm thickness fit standard 120 mm mounting holes?

Yes — the 120 mm square frame uses standard hole spacing; the 38 mm depth only requires clearance behind the mounting surface, and four screws are included.
