  • Excellent Fans — Quiet, Clean, and Easy to Install
Style: LED Normal Blade Size: 3 x 120mm, Black
These Lian Li UNI Fans exceeded my expectations. The wireless design and daisy-chain setup made cable management incredibly clean and easy, especially in my build. The RGB lighting looks amazing and syncs perfectly, while the fans stay very quiet even under load. Airflow and cooling performance have been excellent, and the overall build quality feels premium. Installation was straightforward and they gave my setup a much cleaner look. Definitely worth the price if you want high-end aesthetics and performance for your PC build. ... show more

  • Excelente producto, materiales y conectividad.
Style: LED Normal Blade Size: 1 x 120mm, Black
Excelente. Se sincronizó bien con un adaptador Flex wireless que vino con la refrigeración líquida Hydroshift II CS. El problema del parpadeo que tienen algunas personas se debe a que hay que entrar en la UEFI de la mother y subir la velocidad de los coolers al 100% para que le entreguen la energía necesaria a los cabezales PWM, luego se gestiona la velocidad a través del software L-Connect. Otra opción es conectarlos también a la fuente a través del adaptador que trae. El software no es mui intuitivo y se debería pulir más pero cumple y se puden configurar perfiles para la velocidad del ventilador así como el ARGB o sincronizarlo con otros Fans instalados compatibles con L-Connect. En cuanto a los materiales es de lo mejor que he tenido, me parece excelente las placas de aluminio en los centros ( a mi particularmente no me gustan los espejos infinitos) tanto delanteros como trasero. Creo que es algo que deberían hacer todos los fabricantes de Fan. Las tapas de los agujeros de tornilos que no se usan también me parecen un detalle que hace la diferencia. ... show more

  • Great, fun, and functional fans
Style: LED Normal Blade Size: 3 x 120mm, Black
These fans have worked great when it comes to colors. The screen is not working well. The forms say it is due to the coding. It is slowly eating itself and the process to stop this is advanced nerdy and 24 hour timeline to do correctly. But when the screen works it is cool! Fans have worked great and the lighting around them awesome. Just the Lian Li screens are not working well. I have another single 120m fan with a screen that sometimes doesn't work but does work more often (to be fair it has less it can display compared to the 3 fans fancy screen). ... show more

  • Linux users beware.
Style: LED Normal Blade Size: 1 x 120mm, White
I got a three pack of used ones somehow. I’m not complaining. They work, the box was just super beat up. The fan is as quiet and configurable as you would expect from a lian li product. One thing I did. It realize is the controller software doesn’t work on Linux. I booted to a portable windows disk to set the firmware presets. That way I could adjust how I wanted. They did not connect the same way as the previous generation. But they look and perform well. ... show more
