The fans aren't moving and don't illuminate.
You just finished assembling your PC and now upon turning it on, the case fans aren’t activating. You’re using the LIAN Li uni fan SL-inf 120 with an included USB hub. Two sets of three fans are connected to the hub, along with your AIO fans. The AIO fans are functioning normally—RGB and speed adjustments work—but the case fans remain silent or fail to spin. You’ve tried the L-connect software with your motherboard BIOS, but it didn’t help. When you select “All Full Speed,” only the AIO fans increase in power. Your hub is linked to specific headers on the motherboard: USB (two separate headers), SYS_FAN2, JRGB_V2_1, and two SATA power connectors. Fans are connected to ports 1 and 2, while the AIO fans plug into the third port. Could there be an issue with the fan group configuration or wiring? Let me know if you have more details and I’ll help further! Thanks in advance!
