## Customer Reviews

### ⭐⭐⭐⭐⭐ Love these fans.
*by R***D on January 4, 2025*

I have purchased nothing but Lian Li UNI fans since the first generation. Love the look of these. I just wish I would've waited another month for the reverse blade fans to come out.

### ⭐⭐⭐⭐⭐ Look great cool great
*by A***R on January 15, 2025*

They look fantastic, you cant hear them and the software doesnt suck? Man lian li out did themselves. Nost fan software for rgb is trash. This was fantastic easy setup and forget love it.

### ⭐⭐⭐⭐ Beautiful
*by S***G on April 17, 2023*

The best looking fans...i bought a 3pack and after 2 months one of the fans wont spin. I was just unlucky...all my other 3packs still spins. Sometimes there will be one fan which can be defective but still the best fans.
