Power Makes it Hot

The computer power supply can cause a lot of heat, yet it can also provide the best defense against it. Since just about everything else in the computer generates heat too, a strong fan is essential. Power supplies will have built-in fans that are meant to cool the inside of the computer case to stop components from overheating. Older PSUs have standard box fans, while newer models might have an open design that produces more airflow. When shopping around for a PSU make sure to look for one with a higher power fan. A fan that can vary speeds based on the internal temperature of the computer is ideal. A stronger fan in your power supply will also produce more noise than a slower one. This may not be noticeable, depending on the material your case was built from and if you use rubber alternatives to the standard metal screws inside. If it is noticeable there are other noise-dampening alternatives available, though a little noise is better than your system heating up like a frying pan and sizzling out on you.
