Phanteks PH-F120D30R_DRGB_PWM_BK01 120mm 30mm reverse airflow case fan

Reverse-airflow 120 mm case fan

The Phanteks D30-120 Reverse model is a 120 mm case fan with a 30 mm thick frame designed for builds that need intake or exhaust in the opposite direction of a standard blade. It targets enthusiasts who want visible DRGB lighting on both the frame and the blades while pushing air through restrictive radiators or dense mesh. The single-fan pack suits radiators, top-mounted exhausts or side-panel intakes where reverse flow keeps the illuminated side facing the viewer.

PWM install with daisy-chain linking

Installation uses a standard 4-pin PWM header for speed control between 250 and 2000 RPM. The integrated fan-linking system lets multiple D30 units connect in series with bridge connectors and screw cover plates, reducing cable count to a single lead back to the motherboard. Builders should verify case clearance for the 30 mm thickness and confirm their board provides enough PWM headers or a powered hub for the desired fan count. The Fluid Dynamic Bearing requires no extra lubrication.

30 mm thickness limits case compatibility

At 30 mm thick the fan exceeds the standard 25 mm slot found in many compact chassis and some all-in-one liquid coolers, so it will not fit every mounting point. Maximum airflow is rated at 61.5 CFM with a noise ceiling of 31.8 dB(A) at full speed, figures that apply only when the fan receives unrestricted voltage from the PWM source. DRGB lighting relies on a 5 V 3-pin digital-RGB header or a compatible Phanteks controller; boards limited to 12 V 4-pin analog RGB cannot drive the addressable LEDs.
