Make sure it doesn't lose its cool

The temperature of your computer’s processor is one of the most important metrics to keep a close eye on. If these temperatures get too high, the CPU will reduce its performance, slowing down your computer and shortening its lifespan.

To make sure your PC doesn’t overheat, you’ll need a dedicated tool to monitor CPU temperatures in real time. But which tools should you use? Are there free, easy-to-use apps that provide accurate data about your processor? To answer these questions, we’ve put together a list of the six best CPU monitoring applications.

Modern processors don't really have one clock speed. They have a range of frequencies and their speed depends on their temperature.
