## Questions & Answers

**Q: Previously Working TL/SL LCD Fans Now Uncontrollable (e.g. 2 or 3 fans, one screen fails to respond)**
A: 1.Confirm power source SATA or an external PSU. 2.L3 latest version. 3.Uninstall it from device manager, shut down, unplug and replug the fans, then restart to force Windows to rescan USB devices. 4. Remove USB cable and clean USB path.

**Q: LCD Appears in L3 Utility But Won’t Respond**
A: 1.Confirm power source SATA or an external PSU. 2.L3 latest version. 3.Switch to another tab and back, then click the LCD group again. If the fan disappears, click Restart LCD to reinitialize USB.

A: 1.Binding/unbinding and lightbulb click works, but lighting signals are received inconsistently or slowly by some fans. 2.L3 takes a long time to launch or until restart. 3.Lighting effects like Quick Sync or Merge show jittering/glitching.

### ⭐⭐⭐⭐⭐ Wow amazing
*by M***E on September 3, 2025*

They are the first 3 at the front. They are beautiful and easy to configure.

### ⭐⭐⭐⭐⭐ Best looking fans on the market
*by W***T on August 5, 2026*

Lian li fans are the way to go, definitely on the pricier side for fans but it’s worth it- best looking fans on the market, easy to use and set up- L-Connect software is also easy to use. Keeps my components cool- gpu doesn’t get above 65- replaced my arctic freezer fans with Lian li also and it seems to work better- it’s also a lot quieter.

### ⭐ Stopped working quickly and awful customer service.
*by R***R on June 23, 2026*

They look great when they work. Both fans stopped working properly within a few weeks. One started squeaking like crazy and the LCD screen stopped responding on the other. Created tickets with the support team and that has been an absolute nightmare. I cannot state more just how bad they've been. It's been almost 7 weeks at this point and we are still trying to figure this out. It often takes them up to a week to respond and their responses are often extremely short and shallow. It has been an absolutely frustrating experience. If I had it to do over again I would not get the LCD screens and just stick with their other fans.
