BGears b-PWM 80 Red 80mm Case Fan 500-4000 RPM 78 CFM 37 dBA 2 Ball Bearing Red

Compact 80 mm PWM Fan

The BGears b-PWM 80 Red is a single 80 mm case fan built for systems that need focused airflow in tight spaces. It spins from 500 to 4000 RPM with a tolerance of 10 percent, delivering up to 78 CFM at a maximum of 37 dBA. A 4 pin PWM connector and an included 3 to 4 pin Molex adapter let the motherboard or a controller manage speed automatically.

Wide Speed Range Upgrade

This model replaces fixed speed 80 mm fans that only run at one voltage, giving you a 500 to 4000 RPM window instead of a single operating point. The jump is worth it when your chassis has limited intake room but the components inside still need variable cooling that reacts to load changes. Fifteen aerodynamic blades and a 2 ball bearing are designed to keep airflow stable across that whole range.

Builders With 80 mm Mounts

It suits builders populating 80 mm mount points in compact cases, rack units or legacy enclosures where larger fans will not fit. The translucent red blades and red LEDs add a coloured accent without extra wiring. Buyers who need more static pressure for dense radiators or who want a larger diameter fan for lower noise at equivalent airflow should look at something else.
