Two-Fan Pack for 140 mm Mounts

This pack contains two 140 mm case fans with white frames and addressable RGB lighting. Each unit uses a hydraulic bearing and a 7-blade design rated for 77.37 CFM at up to 1500 RPM. They connect via standard 4-pin PWM and 3-pin 5 V ARGB headers. The fans suit builders who want synchronised lighting across a pair of matching units.

Daisy-Chain Cabling Reduces Header Use

Both fans support daisy-chaining for power and ARGB signals, so a single PWM header and a single 5 V ARGB header can drive the pair. The 25 mm thickness fits typical case and radiator mounting points without extra brackets. Anti-vibration corners help decouple the frame from the chassis. Builders with limited motherboard headers or tight routing space gain a cleaner install.

Hydraulic Bearing Holds Steady at Speed

The hydraulic bearing maintains consistent rotation across the 500 to 1500 PWM range, keeping airflow near 77.37 CFM while noise stays around 30.5 dB-A at maximum speed. The solid frame resists flex during long sessions, preserving blade clearance and bearing alignment. Users who run fans at high duty cycles for extended periods get stable output without rattling or drift.

Questions about this item

What is the maximum airflow each 140 mm fan can deliver at 1500 RPM?

Each fan reaches 77.37 CFM at the top PWM speed of 1500 RPM, using a 7-blade design optimised for static pressure on radiators or case meshes.

How much noise does the hydraulic bearing produce at full speed?

The spec lists 30.5 dB-A at 1500 RPM, so a pair running all day stays in the low-30 dB range typical of quiet hydraulic-bearing fans.

Which motherboard headers are needed to run both PWM control and ARGB lighting?

One 4-pin PWM header for speed control and one 5 V 3-pin ARGB header for the 9 addressable LEDs; the daisy-chain cables let both fans share each header.
