What are two major disadvantages of overclocking the CPU?

Overclocking a CPU involves running it at a higher clock speed than the manufacturer intended, which can lead to two major disadvantages: increased heat output and voided warranty.

When a CPU is overclocked, it typically generates more heat due to increased voltage and frequency. If not managed properly with adequate cooling solutions, this excess heat can lead to thermal throttling, hardware damage, or reduced component lifespan. Effective cooling becomes essential, which in itself can add to the overall system cost.

Additionally, most manufacturers have specific policies regarding warranties that state overclocking a CPU voids the warranty. This means that if the CPU, or even other components in the system, fail due to issues arising from overclocking, the manufacturer will not cover repairs or replacements. This risk is significant for users considering overclocking, as it exposes them to potential additional costs should something go wrong.

In contrast, higher performance or longer lifespan, reduced energy consumption, and improved cooling do not accurately reflect the typical consequences of overclocking; hence they are not valid disadvantages in this context.
