Compact 50 mm case fan

The Amamax 50x15 mm 12 V 3-pin fan spins at 4500 RPM and moves 10.83 CFM through a ball-bearing motor. It fits tight spaces where larger coolers cannot go and draws power from a standard three-pin header. The unit was first listed by the manufacturer in 2019.

Small-form-factor builders and upgrade installers

This fan suits compact chassis, rack mounts or GPU coolers that accept a 50 mm frame and a three-pin connection. It will not suit builds that need higher static pressure, PWM speed control or a four-pin header for automatic fan curves.

Straightforward three-pin installation

Connect the three-pin plug to any 12 V motherboard or controller header and secure the fan with standard 50 mm mounting holes. The ball bearing reduces startup friction, but the fixed 4500 RPM speed means noise stays constant and cannot be lowered by software.

Questions about this item

Does the 3-pin connector on this 50 mm fan fit a standard motherboard header?

Yes, the 3-pin power connection plugs directly into a 12 V motherboard fan header or a compatible fan controller.

Will the 4500 RPM speed damage older components that expect slower airflow?

The fan spins at 4500 RPM and delivers 10.83 CFM, so it provides stronger cooling than many legacy 50 mm fans; ensure your chassis has clearance for the 15 mm thickness.

How can I confirm the ball-bearing fan is running correctly after installation?

Listen for a steady hum at 4500 RPM and check BIOS or monitoring software to verify the reported speed matches the 4500 RPM specification.
