On my Mac Pro 2012 5,1 144.0.0.0.0 i've noticed my Kernel_task is eating up 55-64% CPU just idling after a fresh reboot.
It does this in El Cap, HS, Mojave, Catalina, and up to Sequoia with OCLP. I tried leaving each system idling for an hour to see if it goes away but it doesn't. Nothing in the pcie slots just a gpu. Temperatures all seem fine on the sensors. (CPU A is 20deg warmer than CPU B though) not sure if that's an issue here.
I tried zapping pram, 3 bongs even. Deleted all boot-args. Disabled SIP, tried different gpu's, scanned hard drives for issues. 1 drive has a EFI partition error but that's because Mojave shares a drive with Big Sur (i'm assuming confusion?), tells me to fix it in Recovery Mode but when i try it doesn't let me fix it.
Next i will try removing all hard drives and monitoring kernel_task with 1 drive at a time. Maybe also a cpu tray swap.
In Windows 10 the cpu is 0-2% just purring like a kitten at idle no issues.
I'm running out of ideas on what else to try. Any suggestions or similar experiences ?
