I have the same issue. 2 out of 7 fans LED no longer lights up. When you start the computer the fans all light up. When I enter my password and login the 2 fans that were on are now off. When I open icue link software it only reads 5 out of the 7 fans. The fans are visible in temperature control but not picked up by the rest of the software so I can't change lighting. I attempted to purge residual power from the computer and start it again but the issue still persisted. I forced updated everything. I unplugged and replugged the fans. Nothing works to get those two fans to light up. All this happened after the firmware update. It was an immediate change.
