120 mm dual-sided infinity mirror fan

The darkFlash INF34R is a 120 mm case fan with a 28 mm frame and reverse blades. Hydro bearing construction is rated for 40000 hours MTTF. PWM control adjusts speed between 800 and 2000 RPM, delivering 50 to 55 CFM at 30 to 35 dBA. It targets builders who want addressable RGB lighting on both sides of the fan.

Snap-on daisy chain and splitter cable

A magnetic splice connector lets multiple units link without extra cables, and the 90 degree rotatable plug eases routing. The box includes four anti-vibration pads, four mounting screws and a PWM/ARGB splitter cable for motherboard headers. Buyers who need a controller or hub for systems lacking a 5 V 3-pin ARGB header are not served by this kit.

5 V 3-pin ARGB motherboard sync limit

Lighting runs on the 5 V 3-pin ARGB standard and synchronises with ASUS Aura Sync, MSI Mystic Light, GIGABYTE RGB Fusion and ASRock Polychrome RGB. Boards without a 5 V 3-pin header cannot control the 16.8 million colour effects. The 360 degree illumination and 120 x 120 mm footprint fit most radiators, but thicker radiators may need clearance checks.

Questions about this item

How long is the Hydro Bearing rated to last before it needs replacement?

The Hydro Bearing has a 40000 hour MTTF rating, which translates to roughly four and a half years of continuous operation at full speed.

At the maximum 2000 RPM, what is the highest noise level the fan reaches?

At 2000 RPM the fan produces up to 35 dBA, so it remains relatively quiet even when running at its top speed all day.

Does the 4-pin PWM connector let the motherboard control both speed and ARGB lighting from one header?

The 4-pin PWM header controls fan speed only; ARGB lighting runs through a separate 5 V 3-pin connector that plugs into the motherboard or the included splitter cable.
