Air cooler or liquid cooler? How a CPU cooler keeps your PC fast

A CPU cooler decides whether your processor can run at full speed or has to slow itself down. Learn how air towers and liquid AIO coolers move heat, and why noise matters as much as temperature.

Play with a simple heat model: pick a cooler, push the CPU harder, change the fan speed and watch the temperature, noise and throttling. Then learn what to check before you buy: socket, height and TDP.
