Loud fan and CPU over utilized making the Mac Pro unusable.
I have the same issue with a 6-core Mac Pro. Loud fan and CPU over utilized making the Mac Pro unusable.
Someone was interested in buying it so they took it to a service centre who ran the hardware test and found that some sensors were showing "Can't read". The sensors with a "Can't read" status were listed as 'Ambient MLB', 'Ambient 2', 'Ambient 3', and 'MLB Proximity Local Board'.
Can this be fixed or is it a main logic board replacement thing costing thousands of $$ ?
I don't think I can get away with the kernel task thing in my case. Or can I?
