It is very important that you make the right purchase decision and buy the best 140mm fans. Therefore, I scrutinized my recommendations based on the following factors to ensure that my list is truly the best. Yes, getting the right PC case fan size matters a lot, as 120mm and 140mm fans have different compatibility and performance. Because of their larger size, 140mm fans produce better airflow than 120mm fans. Yes, if your air cooler and PC chassis support it, then you can use a 140mm fan for CPU cooling. You will get better performance and low noise. If your PC case has mounts for both 120mm and 140mm fans, then going with 140mm is the right decision. Since 140mm has larger blades, they don’t need to spin as much as 120mm fans. Hence, their noise output is relatively lower than 120mm fans while their cooling is better. Definitely, 140mm fans perform much better than their 120mm fans. Therefore, if you upgrade your PC case fans to 140mm, then your GPU and CPU’s temperature can be lowered. Recent Updates Thank you!
