Introduction

The Lian Li SL-Infinity 120 RGB Uni Fan (G99.12SLIN3B.00) arrived on my desk promising a compelling blend of performance and aesthetics. This review delves into the performance of this triple pack of 120mm PWM fans, complete with their unique infinity mirror design and customizable RGB lighting. After weeks of rigorous testing, both under load and at idle, I’m ready to share my findings. Let’s dive in.

Features

The SL-Infinity 120 RGB fans immediately impress with their eye-catching design. The “infinity mirror” effect, created by strategically placed reflective surfaces, makes the RGB lighting appear far more expansive and captivating than typical fan RGB. Beyond the aesthetics, the fans boast a 2100 RPM maximum speed, promising significant airflow. The included controller allows for granular control over the RGB, offering a variety of pre-set modes and the ability to customize the lighting to match your system’s aesthetic. The PWM functionality allows for seamless speed adjustment based on your system’s needs, ensuring quiet operation at idle and maximum cooling potential under load. The included controller simplifies this process significantly.

Performance

Testing these fans involved monitoring temperatures across various scenarios. I integrated them into my test bench, initially replacing my stock case fans to gauge their performance in a standard configuration. The difference was noticeable, particularly under heavy load. In demanding tasks like gaming and video rendering, the SL-Infinity 120 RGB fans kept temperatures significantly lower than their predecessors. The 61.3 CFM airflow rating certainly held up. The noise levels were also impressive; even at maximum speed, the fans remained relatively quiet, only becoming somewhat noticeable under the most demanding circumstances. I also ran benchmarks on different configurations, tweaking fan curves to see how responsiveness and noise levels changed. The PWM implementation functioned flawlessly, allowing for smooth speed transitions without any noticeable stuttering.

For a more in-depth analysis, I used various monitoring software to accurately track temperature and RPM data. This data showed that the fans were able to effectively dissipate heat, keeping system temperatures consistently within optimal ranges.

One area worth noting is the controller itself; while functional, it could benefit from a more intuitive interface and perhaps a software companion app for even greater customization options.

Pros & Cons

• Pros: Stunning infinity mirror RGB, excellent airflow, relatively quiet operation, effective cooling performance, easy installation.
• Cons: Controller could use a software interface for enhanced control, price point might be higher than some competitors.

Final Verdict

The Lian Li SL-Infinity 120 RGB Uni Fan (G99.12SLIN3B.00) delivers a captivating visual experience and robust cooling performance. While the price might be a deterrent for some, the quality of the build, the impactful aesthetic design and the effective cooling justify the cost for those seeking both style and substance. I highly recommend these fans for those looking to upgrade their PC’s cooling system and improve the overall aesthetic. The improved airflow alone made a noticeable difference in my gaming sessions.
