80 mm case fan for compact builds

The Athena Power FANC-8020BW3H is an 80 mm square case fan designed for industrial PC chassis and small-form-factor cases. Its 20 mm thickness fits standard mounting points without protruding. The three-pin power connector supplies speed reporting to the motherboard. Ball bearings support continuous operation in demanding environments.

Three-pin connector limits voltage control

A three-pin header allows the motherboard to monitor RPM but cannot regulate voltage the way a four-pin PWM header does. Speed therefore stays near the 3000 to 3499 RPM range unless the board reduces voltage on the pin. Airflow reaches 30 to 35 CFM at that speed with a noise level of 25 to 30 dBA. Builders who need finer low-speed tuning should verify their header type.

Ball bearing and black plastic frame

The ball bearing design reduces friction compared with sleeve alternatives, extending service life in high-temperature enclosures. A black plastic frame and blades keep weight low while resisting vibration. CE and UL certification confirms compliance with safety standards. No LED lighting is included, suiting professional or server installations where visual distraction is unwanted.

Questions about this item

Should I pick the 80mm 20mm thick model or a thinner 80mm fan?

The 20mm thickness moves 30-35 CFM at 25-30 dBA; a thinner 80mm fan typically delivers less airflow at similar noise, so choose this when the chassis has the clearance.

What does the 3000-3499 RPM range mean for actual cooling inside my case?

At that speed the fan pushes 30-35 CFM through an 80mm frame, giving strong spot cooling for drive cages or VRM heatsinks while staying at 25-30 dBA.

How does the 3-pin connector limit speed control compared to PWM?

The 3-pin header allows voltage-based regulation only; the motherboard can vary voltage to change RPM within the 3000-3499 range but cannot send a PWM duty-cycle signal.
