MacOS – kernel_task, high CPU and fans going crazy, no applications open, no launch agents/daemons

kernelmacos

i've tried to debug this for a couple days straight now and can't find out what's causing the kernel_task to go so unruly. i've removed nearly all my third party kexts, done so many etrepro's, and i've been trying to use the console to see repeating errors but it's difficult to follow. i've done all the usual PVRAM and SMC resets etc, booting in safe mode and on a new user. i'm on the latest catalina update. could this be helped by investigating kernel_task deeper, how can i navigate this/keep track of the code to debug what's going on here. thanks in advance for any help. i can upload my current etre pro report/ any else information if needed.

The answer here:

was to switch charging cable side, which i can't do on my computer. I'm more so asking for how I can investigate more intimately or identify what could causing the kernel task to react this way. Thanks

Hardware test gives out:

there may be an issue with the smc PFM006
there may be an issue with the power management system PPN001

Not sure if this will help, but I was getting the same thing on my Mac Mini. Turns out that the temperature sensor wasn't working, and so the fans were on all of the time.
