How Many Fans Should A Gaming PC Have? Guide

A gaming system is created with powerful components to run demanding games smoothly. If you’ve been using your PC to play games for some time, you will definitely understand how crucial it is to keep it cool. An overheating computer can deteriorate the performance of your game, cause significant slowdown, and ultimately destroy your mood. Installing case fans will be helpful to you in this situation. They can stop your PC from overheating, allowing you to have a flawless and fluid gaming experience.

The main threat once it’s related to gaming PCs is the hardware overheating and failing, which is why most builders are worried about it. To keep your PC cool, you must permit air to safely enter and leave the PC casing. You might be curious about the question, how many fans should a gaming PC have while creating one for the first time? There isn’t a single solution since there are different types of PC cases. But we’ll do our best to give you enough details so you can choose cooling fans wisely.

What is a computer fan? 

People can inquire what is a computer fan. A fan is a piece of hardware that moves air into and out of a computer component to maintain the overall temperature of the device or computer. It helps the processor stay cooler by sucking and blowing heated air away. A revolution per minute, or RPM, is a unit used to express how quickly a fan rotates; the more significant the RPM rate, the quicker the fan spins. But frequently, the louder a fan, the greater the RPM rating. You must prefer buying a CPU fan with enough speed capabilities if your computer is overheating

How many fans should a gaming PC have? 

Let’s break them down piece by piece to show how many fans are necessary for a gaming PC. A gaming PC requires a minimum of two case fans to control heat effectively. Three case fans are preferred for ideal cooling, but two are sufficient. If there are three fans, one exhaust fan must be installed on the back panel, one on the front panel, and one as an intake fan. For the greatest performance, installing at least two or three fans in your PC is essential, as the CPU can suffer harm with just one exhaust fan.

The fans start working when we turn on the PC to maintain an adequate temperature. Component fans, such as those for the CPU, power supply, or GPU, shouldn’t be included. In addition, the diameter of the casing also influences the number of fans a PC should have. But the casing must have fan slots to install fans. The airflow of a gaming computer can be configured in various ways. One exhaust fan is situated at the rear or roof of the case, while two or three consumption fans are located at the front.

How can the airflow of a gaming computer operate? 

When we know the number of fans our PC must have, it’s time to understand the airflow of those fans will impact the computer. You will be better able to comprehend how case fans operate. A gaming computer has several distinct types of fans. You need these fans to work in unison to keep the PC cool. Component fans are the initial category of fans. These fans function as exhaust devices, removing heat from the computer’s heating components. However, it is insufficient only to remove hot air from the parts.

You must remove hot air from the PC to prevent temperature spikes. This fan will totally eliminate the system’s heat. Exhaust fans, however, require airflow to operate. Fans for the intake are necessary to control airflow. These fans will draw in fresh, cold air. Simply put, when both of these fans run, airflow occurs. The intake fans draw in cool air, while the exhaust fans exhaust hot air. A good ventilation system not only keeps the PC cool but also boosts gaming performance.

Do two fans sufficiently cool a gaming PC? 

It’s crucial to know whether two fans sufficiently cool a gaming PC or not. Low-end gaming PCs only need two fans. The casing has a single intake fan and a single exhaust fan. If you use the PC for typical computing tasks and light gaming, two fans are plenty. Case fans often have a 1:1 ratio on low-end PCs. A 2:1 or 3:1 fan setup is preferable if you’re using high-power electronics, though. The front can have two or three intake fans installed, and the back might have one exhaust fan.

Using more than two fans will cause negative airflow. It is detrimental to employ many case fans in your system. Stacking actually makes the airflow worse. The first fan on a computer will collide with the other ones and cause less air to circulate inside the device. The PC’s exhaust system won’t be able to eliminate all of the air that the fan is drawing in. As a result, hot air will linger in the PC for an extended time, and even more dust will accumulate.


In this post, we have everything you need to know to decide how many fans should a gaming PC have. We have provided you with all the factors to take into account. The 3-fan design, consisting of two intake fans and one exhaust fan, works best in most situations. After that, it usually enters the declining returns phase because the cost of the temperature differential is no longer justified. When you intend to play video games frequently and upgrade frequently, it is a valuable decision to add more case fans right away.

This is to ensure that you should upgrade by installing case fans to reduce temperatures on CPUs and GPUs with higher performance. When configuring a gaming PC, it is easy to overlook minor details. But over time, your system may sustain serious harm. Therefore, it is essential to insert at least 3 case fans, or 2 intake fans and 1 exhaust fan, into it in order to improve your entire gaming experience and lengthen the lifespan of your PC.

Frequently Asked Questions

Are 4 fans enough for a PC?

Most of the time, a PC with three fans is considered suitable for proper airflow. But if there are four fans, these are more than enough to keep your computer at an adequate thermal level. But ensure to keep these fans at optimal positions to get the most out of them.

How many fans do I need for a 3080?

Having three case fans can keep it in good thermal condition if you have a GPU like RTX 3080 GPU with a 350W TDP value. But ensure to keep these at optimal positions to get impressive results.

Do PC fans increase FPS?

Yes, these do influence fps but indirectly. I mean that PC fans enhance thermal management. And good thermal management increases the GPU overclocking and gaming performance. So have an adequate number of PC fans for an excellent performance.
