Temps jump around during cooling when using SGPro. Go up as high as 98C then to -4, then to 60 then to 20, then to something else. Sometimes will be NA. I also had frost on my chip the other night, even though SGPro said temp was only 14C and anti dew was on. USB3 cable is brand new, and the power supply is a 120v to 12v @ 3A
