6 Months - That's all you get, Enjoy!

Purchased February 2026 - Failed August 2026. Fan was never the quietest even when it functioned. Hey Lian Li, why is L-Connect 3 software download 1.3GB, how much bloatware is in that software and finally why can't it display the device serial number? Want to open a support ticket get ready to pull your fan and search for the tiny serial number.

Software blah

The hardware is so pretty and looks great. The software though, requires setting set every time you boot up the system, these days I leave it on its default rainbow.
