The Empowered PC Mantis 5-Pack Green Halo Ring 120mm LED Desktop Computer Case Fan delivers a balance of performance and affordability for DIY PC builders and system integrators. Each fan measures 120mm in standard frame size and features a green Halo ring LED design that provides understated illumination for case windows or side panels. The fan blades are constructed from durable engineering plastic, which maintains shape stability during extended use. The motor is a fluid dynamic bearing type, engineered to reduce friction noise while sustaining a rated airflow of 45 CFM at maximum speed. This airflow specification makes the fan suitable for general case ventilation, CPU cooler mounting, or radiator applications where moderate static pressure is beneficial. The overall build quality includes reinforced corners and a black frame that resists flexing when installed in tight spaces. In terms of function and efficiency, the fan operates on either a 3-pin DC or 4-pin PWM connector, allowing compatibility with both legacy motherboard headers and modern PWM control. The PWM mode enables dynamic speed adjustment based on system temperature, helping to balance noise and cooling performance. The anti-vibration pads pre-installed on each mounting corner reduce the transfer of motor vibrations to the chassis, contributing to quieter operation. The green LED illumination is not addressable; it emits a steady green glow that provides a consistent aesthetic without requiring additional lighting controllers. The pack includes five identical fans, which simplifies matching airflow and brightness across multiple installation points. Users can expect a maximum rotation speed around 1200 RPM, with a noise level rated below 25 dBA, making it a reasonable choice for quiet computing environments. The materials used in the fan assembly include a reinforced plastic blade hub and a metallic sleeve bearing housing that dissipates heat from continuous operation. The cable length of approximately 400mm per fan offers flexibility in cable management within mid-tower and full-tower cases. The 3-pin connector works with basic voltage regulation, while the 4-pin connector provides PWM precision. The fan’s design prioritizes straightforward installation—no proprietary adapters or additional software are needed. The halo ring LED is located around the perimeter of the fan frame, emitting light through a translucent ring that provides 360-degree visibility without excessive glare. For users building a themed green setup, this pack offers consistent color and brightness across all fans. The product is positioned as a practical value option for budget-conscious builders who require reliable cooling with a touch of lighting. The price point of $12.91 for a five-pack translates to a cost per fan that is lower than many single units, emphasizing the economical nature of this offering. The fans are suitable for use as intake, exhaust, or radiator fans in cases with standard 120mm mounting points. The anti-vibration pads ensure that the fan remains quiet even at higher speeds, while the high airflow rating of 45 CFM per fan supports adequate air movement for systems with moderate heat output, such as those using entry-level to mid-range CPUs or GPUs. The fan does not include a separate fan splitter or hub, so users should plan their motherboard header capacity accordingly.

The Empowered PC Mantis pack provides a straightforward cooling solution that combines functional performance, consistent LED aesthetics, and a highly accessible price.
