overheating fan is making grinding noise, I cleaning with pressure air any dust already, that is not the issue

Unfortunately Apple broke the Apple Diagnostics for some people after a system firmware update and there is nothing you can do to get it working again.
If there is not a foreign object stuck in the fan itself, then the fan bearing is most likely worn out requiring the fan to be replaced.
