Hello guys,

I already reset my PRAM and SMC, but although there is no process running high in the activity monitor, my CPU system is well above 70%. I don't know what else to try. It is a late 2012 retina MacBook Pro, I changed the battery and fans as well and put some fresh thermal compound on the chips. The kernel_task process is at above 500 % Cpu. that will be the problem, but it i seems unrealistically high.

My best regards

There must be a service running, check activity monitor and cycle through the tabs.
