  • TypeCase Fan
  • ColorBlack
  • LEDAddressable RGB

Option 4 Packs

  • 16 million colours ARGB for custom lighting
  • PWM temperature control adjusts fan speed automatically
  • 700-1500 RPM range balances airflow and silence
  • 50 CFM airflow with 1.07 mmH2O static pressure
  • Hydraulic bearings run at 26 dBA for quiet operation

Four-pack ARGB case fans

This set contains four 120mm black fans with addressable RGB lighting. Each unit runs on 12V DC and draws 0.15A through a standard 4-pin PWM connector. Hydraulic bearings keep friction low across the 700-1500RPM operating range. The pack is aimed at builders who want synchronised lighting and quiet airflow in one purchase.

Suits quiet RGB builds.

The 26dBA noise rating at full speed makes the fans appropriate for noise-sensitive desktops. Addressable RGB allows per-LED colour control through compatible motherboard software. However, the 1.07mmH2O static pressure is modest, so builders with dense radiators or restrictive mesh filters should look at fans rated for higher pressure.

50CFM airflow at 26dBA decides fit

At maximum 1500RPM the fans move 50CFM while producing 26dBA, a balance that fits typical mid-tower intake or exhaust positions. If your thermal solution demands significantly more airflow or much higher static pressure, these specifications will fall short of the requirement.

Questions about this item

How do I install the four 120mm fans and connect the ARGB and PWM cables without mixing up the headers?

Mount each fan with the four corner screws, orienting the arrow on the frame toward the exhaust direction. Plug the 4-pin PWM connector into a motherboard CPU_FAN or SYS_FAN header and the 3-pin 5 V ARGB plug into a 5 V addressable RGB header — not the 12 V RGB header.

What maintenance will the hydraulic bearings need over time?

The sealed hydraulic bearings are lubricated for the life of the fan and require no user servicing; if noise rises above the rated 26 dBA or speed drops below 700 RPM, replace the affected unit.

At what point does the 1.07 mmH₂O static pressure limit airflow in a dense radiator or filter stack?

The 1.07 mmH₂O rating is the maximum static pressure the fan can produce; when the resistance of a radiator or thick dust filter exceeds that value, airflow will fall below the 50 CFM free-air figure.
