80 mm sleeve-bearing case fan

The Antec PRO 80MM is an 80 mm case fan that spins at 2600 RPM to deliver 34 CFM of airflow at a rated 30 dBA. It is intended for builders who need a compact cooling solution for tight chassis or targeted component airflow. The black plastic frame measures 3.14" x 3.14" x 0.99" and weighs approximately 0.3 lbs.

Dual 3-pin and 4-pin connector installation

The fan ships with both a 3-pin and a 4-pin power connector for broad motherboard and controller compatibility. Mounting uses standard 80 mm screw holes, so no special brackets are required. The sleeve bearing keeps initial cost low but can become noisier over time compared with ball or fluid-dynamic bearings, especially if the fan is mounted horizontally.

34 CFM airflow for confined spaces

At 34 CFM the fan provides enough volume to exhaust heat from small-form-factor cases, drive cages or GPU backplates where larger fans will not fit. Headroom is limited by the 80 mm diameter and 2600 RPM ceiling; it will not move sufficient air for high-wattage CPU coolers or multi-GPU configurations that demand higher static pressure or greater volumetric flow.

Questions about this item

How do I verify the fan is spinning at its rated 2600 RPM after installation?

Use your motherboard BIOS or a hardware monitoring utility to read the fan header speed; it should report close to 2600 RPM at full duty cycle.

What comes in the box and is anything else needed to mount it?

The package includes the 80 mm sleeve-bearing fan with both 3-pin and 4-pin connectors and mounting screws; no extra parts are required for a standard case fan slot.

Which connector should I choose, the 3-pin or the 4-pin?

Plug the 4-pin connector into a PWM header for automatic speed control; use the 3-pin connector if your board only offers voltage-controlled headers.
