The CPU (Central Processing Unit) is often called the “brain” of your computer, handling millions of calculations and tasks every second. As CPUs become more advanced and powerful, they also generate more heat. Managing this heat is critical for maintaining system stability, ensuring peak performance, and prolonging the lifespan of your hardware. One question that often arises, especially among new PC builders and enthusiasts, is whether a normal cooling fan-such as a standard case fan-can be used to cool a CPU, or if a specialized CPU cooler is truly necessary.
