Final answer:
A broken fan can cause overheating damage to the CPU.
Step-by-step explanation:
A broken fan can cause overheating damage to the CPU. The fan is responsible for cooling down the CPU by circulating air and dissipating heat. If the fan is broken or not functioning properly, it will fail to cool the CPU, resulting in elevated temperatures. This can lead to permanent damage to the CPU, causing it to malfunction or even fail completely.
