How Many Case Fans Do You Need for a Custom Gaming PC?

The cooling airflow of your case is important for any PC that you are going to build, whether it’s a custom gaming PC, a pink PC, or even a mini gaming PC. The first step of making sure that you have proper cooling is getting the correct amount of fans to pull enough air through the system so that all the parts inside aren’t overheating and throttling down. The question is: How many case fans do you actually need?

Proper Airflow Is Important for Any Custom Gaming PC

Proper cooling in your PC does depend on the case as well as the parts you have in the system. Different cases are going to need different amounts of fans to cool them based on how they were designed. Also, if you get higher-end parts, such as those often found in high-performance custom gaming PCs, those are going to run at higher temperatures and produce more heat in your system as a whole. You will usually need more fans when you get a larger case, though compact builds like mini gaming PCs may require careful airflow planning despite having fewer fans as they can produce the same amount of heat.

Mid-Tower Cases for Custom Gaming PC Builds

Typically, for an average mid-tower PC, you should have around four to seven fans in total. This would include the two or three fans that you have on the liquid cooler in the PC (or the fans in the same position if you are using an air cooler) and the rest of the case fans—around three to four. You’d be on the lower end with 140 mm fans since those take up more space, and on the higher end with 120 mm fans. Whether you’re building a mid-tower custom gaming PC or a stylish pink gaming PC, maintaining balanced airflow is key to performance and longevity.

Other Case Sizes, From Mini Gaming PC to Full Tower

This number changes with different sized cases. For full-tower cases, you’d be looking at around six to ten fans depending on the parts and the cooling setup. Small form factor cases, like many mini gaming PCs, range from around two to four depending on the case and how many fans it can support. Some m-ATX cases can hold up to 10 fans, while the smaller M-ITX cases typically have a couple fewer fan slots due to their compact size.

Conclusion: Building Your Custom Gaming PC with the Right Cooling

Now you know how many case fans are typically needed for standard types of cases. Depending on the specific case, especially if it’s not a standard tower, some mid-tower cases can support up to 10 or 11 fans. For example, the Hyte Y70 case can support up to ten 120 mm fans.
