CPU Cooling - Does temperature impact performance?

The video opens with Linus addressing a frequently asked question: does cooling a CPU actually make it run faster if the clock speed remains the same? He acknowledges that the answer is complex, and notes that he has never formally tested the idea before. The host sets up a real-world scenario using a high-end system and runs baseline measurements to establish a reference point before manipulating cooling conditions. The initial test uses Cinebench R15 to gauge performance at a stable 5 GHz, while monitoring temperatures with multiple tools. This setup establishes a baseline for how the CPU behaves under normal load, confirming that temperature readings can vary depending on the measurement method. The goal is not to chase a fixed speed increase from cooling alone, but to determine whether subzero cooling yields any meaningful performance advantage at the same clock speed.
