80 mm ball-bearing fan for compact cooling

This 80 mm fan uses dual ball bearings and a 4 pin connector for direct PWM control. It draws 14.40 W at 12 V and fits standard 80 by 80 mm mounting holes. The unit is intended for builders who need a replacement cooler in tight spaces where larger towers cannot be installed.

Practical limits of the 4 pin PWM interface

The 4 pin header allows the motherboard to vary speed without voltage drops, but the fan will still spin at its minimum duty cycle when the header signals zero. Systems without PWM headers can run the fan at full voltage only, removing automatic speed regulation. Buyers who want software fan curves tied to specific thermal sensors must confirm their board exposes those controls.

Build quality and daily implications

Dual ball bearings resist dust ingress better than sleeve designs and maintain consistent torque over long running hours. The 38 mm frame depth matches the common 80381 form factor, so the fan aligns with existing screw patterns without adapters. The black frame and absent LEDs keep the appearance neutral for both visible and hidden mounts.

Questions sur cet article

Should I pick the 80 mm 4-pin ball-bearing model or a different size for my case?

The PF80381B1-Q020-S99 is an 80 mm square fan with a 38 mm depth and a 4-pin connector; choose it when your mounting holes and header match those dimensions.

What does the 14.40 W rating tell me about actual cooling performance?

At 12 V the fan draws 14.40 W, giving the motor enough power for high static pressure through dense heatsinks or restricted grilles.

How does the 4-pin connector control speed in practice?

The fourth wire carries a PWM signal so the motherboard can vary RPM precisely without voltage drops, keeping noise low at idle.
