VRM Temp sensors? (Gigabyte 990FX-Gaming) in Hardware monitoring Posted August 16, 2016 · Report reply Cool, works great. I see that what used to be my "Aux" temp got changed to "Motherboard," which makes sense. But my old "Motherboard" temp got switched to "North Bridge". Would that be the CPU NB or the mobo? It seems to follow closely with the CPU's temperature, so I'm thinking it's that. The VRMs are in there, my RAM voltage is in there now... cool... THANKS!
