@johnbill444 - I think you really have a different issue!

Let’s get a better view of things, install this gem of an app! CoconutBattery take a snapshot of the apps main window and post it here for us to see Adding images to an existing question

You might also want to install this great app as well TG Pro I think you'll see the fan is running hard and you might see the CPU running hot. Post a snapshot of the main window, make sure you capture all of the sensors as it exceeds the windows size.

You could also see if running the onboard diagnostics gives you any errors. Restart your system and press the D key. Let us know what the errors are.

When you say fails do you mean over heat or a 100% fail

Hey Bill

Not entirely sure your concern but here is some tips that could help.

  1. To disable overclocking (turbo boost) you will need to use some software to disable turbo boost. If you look this up you can find some software like Turbo Boost Switcher
  2. If the fan runs excessively and the MacBook is hot too often, try to carefully remove the screws and keep track of their placement, remove the bottom and clear any dust from the fan and heatsink. Review the insurrections in the ifixit guides for your laptop.

Best of luck!

Hi james, i downloaded turboboost switcher and it wasnt enabled, the mac runs fine until a certain time. I think this is because this macbook has been tampered with because it was owned by someonr else before. (I bought of cex)
