Kit contents and target builder

The kit supplies three 120mm case fans, a 20-port controller hub and a remote. It suits builders who want synchronised ARGB lighting and centralised PWM speed control across multiple intake or exhaust positions.

Upgrade path and when it matters

The hub replaces separate fan headers and lighting cables by offering ten PWM and ten ARGB ports powered through SATA. The jump is worthwhile when the motherboard lacks enough 4-pin or 5V 3-pin connectors for a full chassis layout.

Airflow capacity and practical limits

Each fan moves up to 46.7 CFM at 1600 RPM while peaking at 27.7 dBA, with a 800 RPM floor for quieter operation. The hydro bearing and rubber pads keep vibration low, but the 25mm thickness and fixed 120mm frame restrict use to standard mounting points.

Questions about this item

Will three 120 mm fans with 25 mm thickness fit my case's front panel?

Each fan measures 120 x 120 x 25 mm, so verify your case has three adjacent 120 mm mounts with at least 25 mm clearance per slot.

How do I connect the 20-port hub so both PWM and ARGB work, and what step is often missed?

Plug the hub into a SATA power connector from the PSU, attach up to ten 4-pin PWM fans to the PWM ports and up to ten 5V 3-pin ARGB fans to the ARGB ports, then link the hub's motherboard ARGB header — forgetting the SATA power is the common mistake.

When will the hydro bearing fans or the 24 LEDs need attention?

The hydro bearing is rated for long life with no lubrication required; the 24 LEDs per fan are solid-state and need no replacement, so only occasional dust cleaning is expected.
