A modest CPU overclock can easily add 50-100W to the system's load power, while an aggressive GPU overclock can add even more. Therefore, overclocking should be approached with caution, requiring adequate cooling solutions and careful monitoring of temperatures and power draw.

Undervolting: The Quest for Efficiency

Undervolting is the opposite of overclocking. It involves reducing the voltage supplied to a component, which can lower its power consumption and temperature without significantly impacting performance.

In some cases, undervolting can even improve performance by preventing thermal throttling, where components reduce their clock speeds to avoid overheating. Undervolting can be a complex process, requiring careful tweaking and testing to ensure stability. However, the potential benefits in terms of power efficiency and thermal performance make it a worthwhile endeavor for many gamers.

Thermal Throttling: A Performance Bottleneck

Thermal throttling occurs when a component, typically the CPU or GPU, reaches its maximum operating temperature. To prevent damage, the component automatically reduces its clock speed, which results in a drop in performance.

This is why adequate cooling is essential for maintaining optimal performance, especially in high-end gaming PCs. A powerful cooler can allow components to operate at higher clock speeds for longer periods without triggering thermal throttling, ultimately leading to a better gaming experience. While a beefier cooler might draw a bit more power, the sustained performance gains can often offset this increased consumption.
