What is the main risk associated with overclocking?

The main risk associated with overclocking is that it can damage the CPU. Overclocking involves running a processor at speeds higher than its rated specifications, which can lead to excessive heat output. If the cooling system is not sufficiently capable of dissipating this added heat, the CPU can suffer from thermal stress, potentially causing permanent damage to the processor.

This damage can manifest as instability, crashes, or even complete failure of the CPU, which is why manufacturers often advise against operating outside the designated specs. While the other risks mentioned—such as voiding warranties and potentially harming the cooling system—are valid concerns, the primary and most immediate risk of overclocking is the physical harm it can cause to the CPU itself due to overheating and inadequate power management.
