High-Airflow 140 mm Case Fan

The BGears b-Blaster 140 is a 140 mm case fan built for systems that need strong airflow. It spins at 1800 RPM to move 103 CFM of air while keeping noise at 36 dBA. The fan suits desktop builders upgrading case, power-supply or CPU-heatsink cooling with a single high-performance unit.

Dual Ball Bearing and 3-Pin Connector

A 2-ball bearing design extends operating life and sustains the high 1800 RPM speed. The 25 mm thick frame fits standard 140 mm mounting points in most cases. A 3-pin connector plugs directly into a motherboard header for speed-signal feedback, and a 3-to-4-pin Molex adapter is included for direct power-supply connection.

Upgrade from Slower or Sleeve-Bearing Fans

This fan replaces lower-RPM or sleeve-bearing models that cannot deliver 103 CFM at comparable noise. The jump is worth it when your build demands maximum airflow through a 140 mm slot and you prefer the longevity of ball bearings over quieter but shorter-life alternatives.

Otázky k tomuto produktu

What does the 3-pin connector limit for speed control on this fan?

The 3-pin connector provides a speed signal output but limits control to voltage adjustment; PWM duty-cycle control is not available with this interface.

What clearance does the 140 mm by 25 mm frame need inside the case?

The fan requires a 140 mm square mounting area and 25 mm depth clearance from the mounting surface for the frame and cable routing.

How is the included 3-to-4-pin Molex adapter wired, and which lead is often overlooked?

Connect the fan's 3-pin plug to the adapter, then the 4-pin Molex to the power supply; the yellow 12 V lead on the Molex must be seated fully or the fan will not spin.
