Montech HP140B3IN1 140mm ARGB PWM case fan 3-pack

Three-Fan ARGB Kit

The Montech HP140B3IN1 packs three 140mm ARGB PWM fans and a 6x6 hub into a single box, giving builders a ready-made airflow upgrade for mid-tower or full-tower chassis. Each unit runs on a standard 12 V 4-pin header so motherboard software can sync lighting and speed curves without extra controllers. The rifle bearing design targets longevity while keeping the acoustic profile low for daily desktop use.

Rifle Bearing And Hub Wiring

A rifle bearing sits between sleeve and ball types, offering quieter start-up than ball bearings and better dust resistance than plain sleeves, which helps the fans maintain consistent performance over time. The bundled 6x6 hub consolidates six PWM and six ARGB connections into one CPU-fan header and one 5 V ARGB header, reducing cable clutter behind the motherboard tray. Black frames and blades keep the look neutral whether the LEDs are active or off.

600-1600 RPM Range And 29.2 dB

Speed scales from 600 to 1600 RPM under PWM control, delivering up to 95.61 CFM at the top end while the manufacturer rates noise at 29.2 dB at typical load. At lower duty cycles the fans move useful air — around 90.5 CFM — while staying nearly inaudible in a closed case. The 12 V DC input draws modest current, so a standard fan header or the supplied hub handles power without requiring a dedicated high-wattage rail.
