Which are two major disadvantages of overclocking a CPU?

1. Increased heat output; Reduced clock speed

2. Higher performance; Lower cost

3. Increased heat output; Voided warranty

4. Increased longevity; Better stability

The correct answer is: Increased heat output; Voided warranty

Choosing the option identifying increased heat output and voided warranty effectively highlights two significant disadvantages of overclocking a CPU. When a CPU is overclocked, it operates at higher clock speeds than its manufacturer specifications, which inevitably results in increased heat production. This excess heat requires efficient cooling solutions to prevent thermal throttling or damage to components. If the cooling fails or is insufficient, it can lead to hardware failure, crashes, or a shorter lifespan of the CPU. Additionally, many manufacturer warranties become void when a CPU is overclocked. Manufacturers typically design their products to function within specified parameters and overclocking pushes them beyond these limits. Should a problem arise due to overclocking, the manufacturer might refuse to repair or replace the CPU under warranty, leading to potential financial loss for the user. This understanding emphasizes the risks associated with overclocking, making it a less favorable option for many users who either require stable performance or wish to maintain warranty protection.
