80 mm hydro-bearing PWM case fan

This 80 mm case fan uses a hydro bearing and a 4-pin PWM connector to deliver 5500-5999 RPM and 60-65 CFM of airflow. It runs on 12 V at 0.65 A and produces noise levels above 50 dBA. The frame measures 80 x 80 x 25 mm and weighs 75 g.

Builders needing high airflow in tight spaces

The fan suits compact chassis or targeted component cooling where an 80 mm mount is required and strong airflow is preferred over silence. It is not suited for builds that prioritise quiet operation or for systems that only offer 3-pin voltage control without PWM support.

4-pin PWM connector

The 4-pin PWM interface allows the motherboard to regulate speed automatically across the 5500-5999 RPM range. Without a PWM header the fan will run at full speed continuously, which may be too loud for noise-sensitive environments.

Questions about this item

How can I confirm the fan is spinning within its 5500-5999 RPM range after installation?

Check the fan speed reading in BIOS or monitoring software; it should report between 5500 and 5999 RPM under load.

What comes in the box and do I need to buy a separate adapter for the 4-pin PWM connector?

The box contains the 80mm fan with a 20cm 4-pin cable; no extra adapter is required for standard motherboard headers.

Should I choose the 60 CFM or 65 CFM version for better cooling?

This single model delivers 60-65 CFM across its speed range; there are no separate versions to select.
