Question what do these mobo temp readings in iCue relate to? (ASRock X870 Steel Legend mobo)

[Dunkz]

I'd like to know what each of these temp readings relate to if anyone can help?

Especially Temp1 seems to always be 88 degC and Temp5 high as well. Just wondering what they relate to because i am not sure what on the mobo is hitting those temps?

any info on what any of these temp readings are is appreciated!

Thanks
