If it was actually that hot your motherboard would have shut down to prevent itself from melting. That's likely a misread.
Use HWInfo or HWMonitor to check sensors and see if you can figure out which one is reading that way. "Temp #6" is meaningless on its own unless you have a way to get more details out of that application.
Edit: Just realized this is for iCue, which is a Corsair product and not Asus. You can pretty safely ignore this, it's misreading something.
