Fan Lian-Li UNI SL-INF 140 ARGB PWM - Black

UNI SL-INF 140 ARGB PWM from Lian Li is a 140 mm case fan aimed at more serious gaming and enthusiast configurations, where you want both cooling and a clean, tidy appearance. The 140 mm format provides greater airflow at lower RPM compared to 120 mm fans, helping to create a more comfortable noise background. The noise level of up to 28 dBA is a good balance between performance and silence for a standard gaming or work desktop. The built-in ARGB allows you to synchronize the lighting with the rest of the system and maintain a unified visual style.

What you get is a case fan that connects directly to the motherboard or controller, without unnecessary gymnastics. With 4 PIN PWM control, you can set the RPM curves based on temperature, so the machine is quiet at idle and more aggressive under load. Through the 3 PIN 5V ARGB header, you integrate the fan into the overall RGB ecosystem of the motherboard – colors, effects, and synchronization with RAM, GPU, and other fans. With the 140 mm format, you can use fewer fans for the same airflow, simplifying cables and reducing potential noise. Combined with a 24-month warranty, you get a reliable component that you can confidently include in your main build.

• Size 140 mm – a larger fan means more air at lower RPM, convenient for quieter gaming and work systems.
• Noise level up to 28 dBA – suitable for cases that sit on your desk without drowning out the sound from games or music.
• 4 PIN PWM connector – allows you precise control of the RPM through BIOS or software and the setup of custom cooling profiles.
• 3 PIN 5V ARGB Header – direct connection to the motherboard or controller for synchronization of lighting with other ARGB components.
• ARGB lighting – gives you the ability for dynamic lighting effects and color schemes without sacrificing functionality.
• Application: case cooler – ideal for front intake or top/rear exhaust airflow in mid or full tower cases.
• 24-month warranty – two years of peace of mind that if something happens to the fan, you have official support.

Who it is suitable for: if you are building a gaming or work computer with a transparent panel and care about both appearance and good ventilation, this 140 mm ARGB fan is a logical choice. It is also suitable for quieter builds where you want PWM control and moderate noise. It is not the most sensible option if you are making a completely stealth system without a window and without any RGB.

The strongest combination here is between 140 mm format, PWM control, and 5V ARGB – you get a fan that you can set exactly as you need, without compromising between cooling, noise, and appearance.
