Three-pack ARGB case fans

The darkFlash INF34 arrives as a three-pack of 120 mm PWM fans built around a hydrodynamic bearing rated for 40000 hours MTTF. Each unit measures 120 × 120 × 28 mm and connects via a standard 4-pin PWM header plus a 5 V 3-pin ARGB lead. The kit includes anti-vibration pads, mounting screws and three splitter cables for daisy-chaining power and lighting.

Sustained thermal behaviour

Under continuous load the fans spin between 800 and 2000 RPM, moving 50 to 55 CFM while producing 30 to 35 dBA. The nine aerodynamic blades are shaped for balanced airflow and static pressure, so performance remains steady during long gaming or rendering sessions rather than dropping off after an initial burst.

ARGB ecosystem limits

The infinity-mirror lighting on both sides supports 16.8 million colours and synchronises with ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion and ASRock Polychrome RGB through a 5 V 3-pin header. Builds without a compatible 5 V ARGB header or without enough headers for the daisy-chain will lose motherboard-level lighting control.

Questions about this item

How loud and warm do the three INF34 fans get when they run at 2000 RPM all day?

At full speed the fans reach 35 dBA and move 55 CFM; the hydro bearing is rated for 40000 hours MTTF, so heat and noise stay controlled during continuous use.

Does my motherboard need a 5 V 3-pin ARGB header and a 4-pin PWM header to run the lighting and speed control on this 3-pack?

Yes, each fan uses a 4-pin PWM connector for speed and a 5 V 3-pin ARGB connector for the infinity mirror LEDs; the pack includes three PWM/ARGB splitter cables for boards with limited headers.

Will the 28 mm thick INF34 fans fit alongside the older 25 mm fans I already have in the same case?

The INF34 is 28 mm thick — 3 mm thicker than standard 25 mm fans — so check your case clearance and radiator mounting points before mixing them.
