Prism 4RS ARGB 120mm Case Fan with Infinity Mirror Design

Prism 4RS ARGB 120mm Case Fan with Infinity Mirror Design blends bold, customizable lighting with dependable cooling for PC builds. Each fan features dual-sided infinity lens lighting enhanced by an axial CD pattern to add depth and drama to your rig, making the display of your components truly pop.

True ARGB control is at your fingertips. The Prism 4RS supports 5V ARGB motherboard interfaces (ASUS, MSI, Gigabyte, ASRock) for software-driven color and effects across 16.8 million colors. If your motherboard offers a 5V 3-pin ARGB header, you can connect directly—no extra controller needed. If not, you can pair the fan with an ARGB controller for full lighting versatility.

Engineered for quiet, efficient cooling, the Prism 4RS uses a 4-pin PWM interface for motherboard-driven speed control, automatically adjusting RPM based on temperature. It rides on hydraulic bearings with a recirculating oil supply, delivering long life and smoother operation. With 9 blades made from high-temperature resistant PBT and vibration-damping silicone pads at the corners, it delivers sturdy airflow while keeping noise low.

Flexibility is built in with reversible airflow directions. Standard orientation is optimal for top and rear placements, while reverse orientation works best for front and bottom positions—letting you showcase the lens and lighting effects from any angle.

Benefits & Tips

• Synchronize multiple Prism 4RS fans across a single ARGB setup to create a cohesive lighting show with 16.8 million colors.
• Use PWM control to balance cooling and acoustics by tying fan speed to system temperatures.
• Position for dramatic visuals: standard airflow for the top/rear, reverse for front/bottom to maximize the Infinity Mirror effects.
