Some Lian Li Uni Fan SL120 Affected by Defective LEDs, Company Offers Replacements | TechPowerUp
 
Lian Li on Monday disclosed that some batches of its Uni Fan SL120 units are affected by defective LEDs. While this defect does not contribute to a safety hazard, it affects quality, and is spread across a fairly big batch. Uni Fan SL120 manufactured between December 2020 and March 2021 are likely to come with a faulty blue LED lighting IC that makes the blue component of the RGB LED deteriorate over time, resulting in dimmer LEDs. When set to white, the RGB LED has a yellowish coloration from the dimmer blue component. The company mentions that units manufactured after March 2021 come with corrections for this issue.

Anyone with Uni Fan SL120 can file for replacements, since they may have thrown away product packaging and may not know their date of manufacture. The replacements can be filed here.
 
It's good to see Lian Li take immediate responsibility and provide replacements.
