Can't upload a picture to this place, so I will list manually what the readings were.
I will keep the screenshot so maybe someday I can upload it.
Core Temp 1.13: 37
MSI afterburner: 37
HWinfo64 V6.00-3620: 36.5
Aida64: 36
Evga Flow Control: 26.5
They are all the same except Evga Flow Control.
So either they are all wrong, or EVGA Flow Control is wrong.
I think the answer is obvious.
