Was this value shown before, did you perhaps update the NVIDIA drivers when it stopped showing it?
Also please attach the HWiNFO Debug File with sensor data so I can see in more detail why it's missing.
@Martin@Owmince - Owmince's advice worked. Thank you both for responding and sorry for the late response... just got around to playing around w/ the 3090 more!
I think the software got confused b/c i was switching GPU's around so much and resetting it gave me the correct settings.
