At the end of 2025 - still best but still problems with app controll
I’ve been using the Lian Li UNI Fan SL Wireless (Reverse Blade) 120mm ARGB Triple Pack for about 6 months now. Performance-wise, they’ve been solid—no issues with operation or cooling so far. Noise levels are also good: they’re basically quiet in my setup, but it really depends on your fan curve, overall settings, and how many fans you’re running. If the curve isn’t tuned and they ramp up to higher RPM, they can definitely become noticeable. That said, I’ve had two main downsides: RGB expectations: I originally bought the SL fans thinking they would have inline RGB lighting in addition to the edge RGB, but I was wrong. They still look very cool, but I may have misunderstood what I read online. L-Connect app reliability: This is the bigger problem. On the SL Wireless fans, L-Connect has been pretty bad for me. Twice in 6 months the fans disappeared from the app, and the only fix was unplugging and replugging the USB connection. Since I connected it directly to the PSU inside the case to avoid messing with ports, re-seating it is annoying and time-consuming—and it can loosen connectors over time. Interestingly, I haven’t had this issue with my wired UNI TL Fans. ... show more

Clean Look, Excellent Cooling Performance
Style: LED Reverse Blade Size: 3 x 120mm, Black
These reverse blade UNI Fans are absolutely worth it for a clean PC build. The reverse blade design keeps the airflow direction correct without showing the back side of the fan, which makes the setup look much cleaner and more premium. Installation was simple thanks to the UNI Fan connection system, and cable management was much easier compared to traditional fans. RGB lighting looks fantastic, airflow is strong, and they stay impressively quiet even during gaming sessions. Perfect choice for showcase builds. ... show more

Great low noise fans
Style: LED Reverse Blade Size: 1 x 120mm, White
while they arent entirely wireless these fans have tons of positive points about them. For one the fact that you dont need a hub to plug them into anymore is nice and even though you need the USB dongle to connect them all it still takes up less space than the original Hub and you dont need to plug it into the motherboard. The other good thing about these fans is they are very quiet, I run a high end mid ranged system for gaming and at 900RPM you can barely tell they are on. highly recommend getting these fans. ... show more
