120 mm dual-sided infinity mirror fan

The darkFlash INF34R is a 120 mm case fan with reverse blades and addressable RGB lighting on both sides. It targets builders who want a clean interior look and synchronised lighting through a 5 V three-pin ARGB header. The white frame and 28 mm thickness suit standard mounting points on cases and radiators.

Snap-on daisy chain with 90° rotatable connector

Multiple fans link together through magnetic splice connectors that rotate ninety degrees for easier routing. A PWM/ARGB splitter cable is included for the first fan. The only common issue is forgetting to plug the 5 V ARGB header into the motherboard, which leaves the lighting inactive while the fan still spins.

PWM speed range 800–2000 RPM and 30–35 dBA

The four-pin PWM connector lets the motherboard vary speed automatically between 800 and 2000 RPM, delivering 50–55 CFM. At the top of the range the fan reaches 35 dBA, so silent builds may need a custom curve. The hydro bearing is rated for 40 000 hours MTTF, but the 28 mm thickness can limit fitment in slim chassis or tight radiator stacks.

Questions about this item

How do I verify the 120mm fan is running within its 800-2000 RPM range after installation?

Connect the 4-pin PWM header to the motherboard and monitor the speed in BIOS or fan-control software; the fan will auto-adjust between 800 and 2000 RPM based on temperature.

Which accessories are included in the single-fan package and what must I source separately?

The box contains one INF34 ARGB fan, four anti-vibration pads, four mounting screws, one PWM/ARGB splitter cable and a user manual; additional fans or a 5V 3-pin ARGB controller are sold separately.

Should I choose the normal-blade or reverse-blade version for my build?

Select the reverse-blade model when you need intake airflow directed away from the motor hub — such as on a radiator push configuration — and the normal-blade version for standard exhaust or intake positions.
