This listing details the physical attributes and connectivity choices available to you when building your PC.
What stands out
- 1.8-inch LCD screen supports various media formats for visual customization.
- Dual-style edge design provides multi-zone lighting effects for enhanced depth.
- 120mm fan size with reverse blade direction for specific airflow needs.
- Flexible control options allow switching between motherboard PWM and L-Connect 3.
Who it fits
Good fit for
You should consider this fan if you are building a PC with a case that supports 120mm reverse blade fans and want to showcase custom visuals. The integrated LCD screen is ideal for users who want to display photos or videos directly on their hardware. It suits builders who value simplified cable management and wireless functionality. If you plan to use L-Connect 3 for full display customization, this unit fits your setup perfectly. It is also a good choice for those who prefer ARGB lighting with a unique, modern aesthetic.
Who should skip it
You should look at another option if you need a controller included in the box, as this single pack does not come with one. Be sure to check your case compatibility for reverse blade fans, as this model is direction-specific. If you prefer normal blade airflow direction, this reverse version will not work for your intake or exhaust needs. You might also skip this if you do not plan to use L-Connect 3, since full LCD functionality requires the USB receiver and software. Additionally, if you need a larger 140mm size, this 120mm model is not suitable for your build.
Verdict: This fan offers a unique blend of 120mm cooling and customizable LCD visuals for specific reverse-blade setups. It is best for builders who want detailed display control and do not mind purchasing a separate controller.
Key specs explained for this fan
Fan Size: 120mm
This measurement defines the physical dimensions of the fan frame. A 120mm fan fits standard mounting holes in most PC cases. You will find these in mid-tower and full-tower chassis. This size balances airflow volume with noise levels. It is the most common size for case cooling. You can easily replace existing fans with this model if your case supports 120mm mounts. It offers a versatile fit for general building needs.
Lighting Type: ARGB
ARGB stands for Addressable RGB. This technology allows each LED to display a unique color and effect. You can create complex patterns and synchronized lighting across multiple fans. This differs from standard RGB, which colors all LEDs identically. This feature suits users who want detailed visual customization. You will need a compatible motherboard header or controller to manage these effects. It provides greater flexibility for aesthetic builds compared to fixed-color lighting options.
Connector Type: PWM
PWM means Pulse Width Modulation. This connector type allows the motherboard to control fan speed precisely. It uses a four-pin connection for power and speed signals. This ensures quiet operation at low loads and maximum cooling under stress. You can adjust speeds directly in your BIOS or software. This is standard for modern case fans. It offers better thermal management than three-pin DC fans. This connector type is widely supported by current PC case designs.
Blade Direction: Reverse
Reverse blade fans push air toward the motor frame. This changes the airflow direction compared to standard fans. You should use these for exhaust mounting or specific intake configurations. This direction affects how air moves through your case. It is crucial for maintaining proper airflow paths. You must check your case layout before installation. This specification ensures you buy the correct version for your desired air direction. It prevents incorrect airflow that could reduce cooling efficiency.
LCD Display: 1.8-inch
This fan includes a small screen on the frame. The 1.8-inch display allows for custom images or videos. You can upload media to personalize your build visually. This adds a unique aesthetic element to your PC case. It requires a specific controller or software to function. This feature is distinct from standard LED-only fans. It appeals to users who want high customization. You should verify compatibility with your control hub before purchasing.
Design and Build Details
According to the listing, the Lian Li UNI Fan SL-INF LCD Flex measures 6.5 inches in width and 5.24 inches in height. The frame thickness is 1.42 inches. The unit weighs 11.4 ounces. These dimensions confirm it is a standard 120mm fan. You can mount it in most mid-tower and full-tower cases without issue. The color is black. This finish blends well with dark interior themes.
The design includes a 1.8-inch LCD screen. This display supports various media formats. You can upload videos and photos for full customization. The listing notes that the USB 9-pin cable is required for this feature. This cable connects to the LCD Flex Receiver only. Without it, you lose video and photo upload capabilities. The controller is not included in this single pack. You must purchase separate components for full functionality.
Lighting uses ARGB technology with a dual-style edge design. This creates multi-zone lighting effects. The reverse blade direction is a key structural choice. You must verify airflow direction before installation. The fan supports motherboard PWM or L-Connect 3 control. This flexibility allows you to choose between wired motherboard headers or wireless controller management. The layout simplifies cable management when using the wireless option. However, the LCD screen always requires the USB connection for advanced features.
Setup and everyday use
Setting up this fan requires careful attention to model selection. The listing notes that a controller is not included. You must check the airflow direction and model type before purchase. Ordering the incorrect version is easy if you do not verify these details. The fan uses a PWM connector for speed control. This allows you to manage rotation via your motherboard headers or the L-Connect 3 software. The unit supports wireless functionality for simplified cable management. This reduces clutter inside your chassis. For daily use, the 1.8-inch LCD screen is the primary feature. It supports various media formats. You can upload videos and photos to customize the display. The dual-style edge design provides multi-zone lighting effects. This enhances visual depth and complements many PC aesthetics. If you connect the USB 9-pin cable, you unlock full LCD functionality through L-Connect 3. This enables complete display customization. You can adjust every aspect of the visual output. The reverse blade direction is a key specification. It affects airflow orientation within your case. Ensure this matches your cooling setup. The ARGB lighting syncs with compatible systems. This provides consistent color themes across your build. The black color option offers a neutral look. It fits well with most modern chassis designs. Overall, the setup involves selecting the right variant and connecting the necessary cables. Daily use focuses on visual customization through the LCD and lighting effects.
Before You Buy This Fan
