    Possible Fan Issues w/ MacBookPro16,1

    I have a 2019 MacBookPro16,1 When I first got it, it seemed to me that the fans were way louder than my previous MacBook. The fans seemed to always be at full blast.

    Boot Camp is casing kernel_task to overclock CPU

    I have a late-2016 MBP (w/ Touch Bar/Retina). Since the last update (to 10.15.5) every time I boot back into macOS from being in Windows 10, kernel_task starts overclocking the CPU. It will run up to near 500%. Regardless of what time of day it is, if I boot into Windows, then back into macOS...
