MacBook Overheating: Causes and Practical Fixes
Understand MacBook heat, loud fans and slow performance before arranging a thermal service.
Warmth during demanding work is normal, but sustained heat, loud fans and performance drops can indicate blocked airflow, heavy software load or a cooling issue.
What the symptoms can mean
Activity Monitor may reveal a process using excessive CPU. Dust, blocked vents or ageing thermal materials can also reduce cooling efficiency.
What to do next
Restart, update macOS, close unnecessary tasks and use the Mac on a hard surface. If heat continues during light use, arrange a cooling-system diagnosis.
When to arrange a diagnosis
If the problem continues after safe basic checks, a proper diagnosis is the best next step. It helps separate a replaceable part from a deeper board, power or software issue before any repair is approved.
