Heat is an inevitable byproduct of computer hardware operation, but too much heat can cause a slowdown across your system. So, the ambient temperature where you place your computer plays a key role in keeping your CPU fan cool. The idle temperatures under which your CPU fan can function optimally ranges somewhere between 32 – 40 Celsius degrees. If the temperature exceeds this range, it can likely warm up your PC.

The commonly used small USB fans, household stand fans, or air conditioners make an ideal setup that can keep the components of your computer, including the CPU fan sufficiently cool and allows you to get the best performance from your system.
4] Install a good airflow solution
You can improve the amount of air that flows in, either by optimizing fan placement or by providing airflow options to the builder. PC fans come in varying sizes (from a common 120mm case fan to more specialized configurations), depths, noise levels, and aesthetic considerations. You can choose the one that optimizes airflow and keeps your PC cool.
