820-01521-A A1932 EMC 3184 Over 150% CPU Used By Kernel_task

[Cire3]

MacBook Air "Core i5" 1.6 13" (True Tone, 2019)

820-01521-A A1932 Over 150% CPU Kernel_task PID 0. Fan running what seems like full speed. Dam near unusable.

Not booting on battery. Super slow. 5 Minutes to click anything.

Removed board, no water damage found. Boots up currently, if you have enough time in a day

Thoughts?

Test with known good battery.

Does it require a battery ? Same issue on the bench without battery.

Fan goes to max speed and system is very slow, if battery is not detected...
