Three-fan ARGB pack with magnetic daisy-chaining

This three-pack of 120 mm PWM ARGB fans uses a patented 7-pin magnetic connector so each unit snaps to the next without extra cables. The 5 V 3-pin ARGB header supports 16.8 million colours and syncs with major motherboard lighting ecosystems. Builders who need 12 V RGB headers or a single-fan kit should look elsewhere.

Hydro-bearing thermals at 30–35 dBA

An FDB hydro bearing rated for 40,000 hours MTTF drives nine aerodynamic blades between 800 and 2,000 RPM, delivering 50–55 CFM while keeping noise between 30 and 35 dBA. Four anti-vibration pads per fan further dampen resonance. The 25 mm slim frame fits standard case mounts and most radiators without clearance issues.

Sustained PWM response under load

The 4-pin PWM link continuously adjusts speed from 800 to 2,000 RPM as system temperature rises, maintaining airflow without sudden spikes. Magnetic daisy-chain wiring stays secure during long sessions, and the hydro bearing maintains consistent torque across extended duty cycles. Users requiring higher static pressure or thicker frames will need a different series.

Questions about this item

How do I install the magnetic daisy-chain connection on the Gauss G24 fans without misaligning the 7-pin connectors?

Align each fan's magnetic connector so the pins seat fully before snapping the next unit; the 7-pin layout only mates one way, and forcing it off-centre bends pins and breaks the ARGB signal chain.

When will the FDB hydro bearing on these 120mm fans need replacement?

The bearing is rated for 40000 hours MTTF; at typical 800-2000 RPM operation that translates to several years of continuous use before wear increases noise or reduces speed stability.

What thermal limit appears first when the three fans run at 2000 RPM for extended periods?

Sustained 2000 RPM operation raises bearing temperature until the hydro fluid viscosity drops, causing RPM to throttle below the 50-55 CFM target to protect the 40000-hour rating.
