Three-Pack ARGB Case Fans

The darkFlash INF34R 120mm reverse-blade fans arrive as a three-pack with 28mm thickness and dual-sided infinity mirror ARGB lighting. Hydro bearings rated for 40000 hours MTTF support a speed range of 800 to 2000 RPM. Each unit delivers 50 to 55 CFM airflow at 30 to 35 dBA noise. A 4-pin PWM connector enables automatic speed control tied to system temperature.

Reverse Blade Upgrade

Reverse blade orientation pulls air through radiators or restrictive meshes more effectively than standard blades in pull configurations. The jump is worth it when your front or top panel mounts fans behind dense filters or thick radiators where static pressure matters. Builders using normal blade fans in those positions will see improved thermal headroom. The magnetic splice design and 90° rotatable daisy-chain connectors simplify cable routing compared to traditional screw-terminal wiring.

ARGB Sync And Daisy Chain Limits

The 5V 3-pin ARGB header supports 16.8 million colours and syncs with ASUS Aura Sync, MSI Mystic Light, GIGABYTE RGB Fusion and ASRock Polychrome RGB. Daisy-chain connectors carry both PWM and ARGB signals but total current must stay within the motherboard header rating. Three included splitter cables provide alternative wiring if the header cannot supply enough power for all three fans. Buyers needing more than three fans on a single header should verify the board's current limit before expanding the chain.

Questions about this item

What clearance does the 28mm thickness need in my case?

The fans are 120mm square and 28mm thick, so each mounting location must provide at least 28mm depth plus room for the daisy-chain connector.

How do I connect the PWM and ARGB cables without a mess?

Snap each fan to the next using the magnetic 90° rotatable daisy-chain connectors, then plug the single combined PWM and 5V 3-pin ARGB leads into the motherboard headers.

When will the hydro bearing need attention?

The hydro bearing is rated for 40000 hours MTTF; plan to check for noise or vibration after extended heavy use.
