A computer isn’t just wires and chips — it’s a machine with moving parts, airflow, and heat to manage.
Mechanical engineering keeps the system physically stable, and thermal engineering keeps it cool enough to work.
Any time electricity flows, heat is generated.
If the heat isn’t controlled, hardware slows down, crashes, or gets permanently damaged.
Computers generate heat because electrons meet resistance as they move through circuits.
When heat builds up:
Engineers design the physical system so heat can escape safely.
