Strange glowing red line on motherboard

[xaowx]

Completely stumped on this and decently concerned.. Computer is working fine. Top video cards temps are a little higher than they used to be but I removed the side fans so thats probably why. Mobo is MSI Z97 Gaming 5. I would take apart the computer to get better pictures and to investigate, but I have a broken hand.

Yes those are case fans superglued to the bottom video card.

ISOLATED AUDIO PCB
With traditional onboard audio the signal is distorted by electromagnetic signals from the rest of the PCB. Audio Boost 2 acts like a dedicated soundcard by physically isolating the audio circuitry which is separated by a red LED path. Less interference gives you a more clear audio signal.
