Longevity of CPUs

Key Points

• Typical Lifespan: CPUs generally last about 10 years.
• Extended Lifespan: Under optimal conditions, CPUs can last much longer.

Example: Motorola 68000

• Historical Use: This CPU was used in the original MacIntosh and Commodore Amiga in the 1980s.
• Current Functionality: Some Motorola 68000-based computers are still operational over 40 years later.

Case Study: Grand Rapids Public Schools

• Usage: The Commodore Amiga, powered by the Motorola 68000, was used for heating and air conditioning control in 19 schools since the early 1980s.
• Replacement: These systems were only replaced around 2015, highlighting the CPU's durability.

Maintenance Tips for CPU Longevity

• Cooling: Use effective cooling methods.
• Dust Management: Ensure the CPU is free of dust and obstructions.

Conclusion

Taking good care of a CPU can significantly extend its lifespan, potentially beyond the typical 10 years.
