There is a minimum amount of fans you need to keep your gaming PC cool at all times when gaming. All the additional fans installed will be just to keep your gaming PC more maintained at your desired temperatures and also when you would want to upgrade some of your parts especially the CPU.
If you have a liquid cooling system for your gaming PC, fans are still needed. These fans are used to ventilate your gaming PC unit and they still play an important role in proper ventilation. While a liquid cooling system can cool your CPUs and GPUs more, the other components still need to be cooled and ventilated with a fan.
This article will be all about teaching you how many fans are needed for a gaming PC and why.
What Do Case Fans Do to Your Gaming PC?
Case fans are responsible for the airflow going around inside your gaming PC. This brings the question, how many case fans do you need? A minimum of 2 case fans is needed. The first one is for taking in the cool here (intake) and the other one is for bringing the hot air out (exhaust).
The CPU is the one that needs most of the cooling and then the GPU. Most builds have their components centralized and have the exhaust behind the gaming PC and have the intake near the drive bay. Most of the heat will be aired out immediately and get replaced by cooler air from the front side of the case.
Even with a liquid cooling system, you still need the airflow inside your gaming PC so you would still need case fans. They keep your other components fresh and not just the CPU and GPU. You would want your components to be around 50 to 70 degrees Celcius. If you can have it lower, it would be a lot better and it will definitely make your gaming PC last longer.
Adding More Than 2 Case Fans
By adding another case fan, it can improve your airflow and overall temperature faster. This depends on your overall gaming PC build and what options you have.
Generally, you can have 2 case fans for intaking cool air. You can also have 2 case fans for exhausting the heat and replenish the cool air faster by removing the heat quicker. The exhaust case fans should be closer to the CPU to be more effective otherwise, you can just go for 2 case fans for intake.
If your gaming PC is not built for the current highest performing parts on the market, you definitely want to have just 2 case fans as it would get more expensive for nothing. You would want the option to add more fans though so you should explore investing in a good gaming case if you are looking to upgrade constantly. Here is our list of the best gaming PC cases out.
It is a good investment to add more than 2 case fans immediately when you are planning on gaming a lot and plan on upgrading consistently. This is so that you never forget that you need to upgrade by adding case fans to improve temperatures on higher performance GPUs and CPUs.
The same logic goes for getting good PSUs, and it keeps your hardware safe from short-circuiting and overheating as those issues damage your costly computer parts in the long run.
