How Many Fans Should A Gaming PC Have?

How Many Fans Should A Gaming PC Have

In the third decade of the 21st century, advancements have been made in video games. They have more intricate mechanics, epic tales, and fantastic visuals. And to obtain the full experience of these games, your hardware must put on a complete performance, which will cause it to heat up. Fans are used to dissipate this heat, but the question is how many fans a gaming computer should have.

When a computer is under load and performing intensive activities, it creates a great deal of heat, which can be mitigated by fans, heatsinks, liquid cooling, and other cooling arrangements. However, the question arises as to how many case fans a gaming PC requires for optimal cooling. Fans are used for air cooling, liquid cooling in radiators, and as basic fans.

How Many Cooling Fans Does A Gaming PC Need?

In a gaming PC, many airflow setups are achievable. However, you’ll need at least three fans to achieve these airflow combinations and ensure adequate system cooling.

In addition, at Toptechstuff, we got the opportunity to test out several cooling systems. And our conclusion is that a neutral/balanced airflow configuration, such as two intake fans and one exhaust fan, will provide the most cooling.

Are 2 Fans Enough for a Gaming PC?

If you are wondering whether or not two fans are sufficient for a computer, here is our verdict. Two fans are sufficient for cooling low-end gaming PCs and general-purpose computers, as they do not do the most sophisticated or intensive activities. In this situation, one fan for intake and one fan for exhaust would be optimal.

You can also attempt a negative pressure airflow design with two exhaust fans and no intake fan. This cooling setup gives the maximum cooling in general. However, it will pull a significant amount of dust and particles inside the PC casing. Therefore, you will need to regularly clean your PC.

Conversely, do not utilise both fans for intake, since this setup will cause more harm than good. Without a mechanism to expel the hot air, your computer will overheat more.

Are 3 Fans Enough for a Gaming PC?

Most users have three fans on their gaming PC, and they frequently worry if this is sufficient. Here is our concise response. In most instances, three fans are sufficient for a gaming PC; but, if overclocking is involved, you will need to invest considerably in cooling. Aside from that, three quality fans will provide sufficient cooling for games and difficult work.

The majority of PCs we test at Toptechstuff (for gaming and other intensive workloads) have three fans. And we rarely experience overheating problems. Regarding airflow configuration, two intake fans and one exhaust fan would be the optimal solution. This arrangement will allow your chassis to continuously receive cooler air and expel hot air.

Are 140mm Fans Better than 120mm Fans? – 120mm vs 140mm Fans

how many fans should my gaming pc have Testing

Here is our brief comparison of 120mm and 140mm fans. In contrast, there is little distinction between 120mm and 140mm fans. In the big scheme of things, however, 140mm fans offer greater RPM and air throw, resulting in superior cooling. Thus, if you intend to change your 120mm fans to 140mm fans, you can anticipate some performance gains.

Therefore, changing from 120mm fans to 140mm fans is a worthwhile investment.

Due to the modest size of their fins, some people believe that 120mm fans produce a greater air throw; however, the difference is negligible and does not have a significant impact on cooling. Moreover, both fans will generate noise due to their high RPM. However, this will also rely on the fan’s brand and quality.

Does Every Case Support 140mm Fans?

If you intend to upgrade your fans to 140mm ones, you must ensure that your chassis is compatible. Since 140mm fans are universally utilised, most quality gaming cases support them. Nevertheless, some containers are constructed differently. Additionally, they may only support diehard fans. Before spending money, you must therefore check the compatibility of your case online.

By default, the majority of cases are equipped with 140mm fans, notably on the front panel.

What Brands are Reputable in PC Fans?

There are numerous manufacturers who produce a variety of PC fans. However, we tested the top Noctua fans (especially Noctua NF-A14 Fan). There are also exceptional Corsair, NZXT, Thermaltake, and Be Quiet fans available. However, you need carefully analyse your alternatives and select the optimal fans for maximum cooling and to avoid excessive heat.

Your personal computer need a steady supply of colder air to reduce the internal temperature. There should be a straightforward method for releasing hot air from the casing. In this way, fan placement can also play an important role.


Monitoring the temperatures of your gear is essential. Heat can reduce performance and ultimately cause hardware damage. The most common cooling solution for gaming and general-purpose PCs is air cooling. In addition to GPU fans, CPU fans, and power supply should be considered while choosing an airflow configuration.

How Many Fans Should A Gaming PC Have?

Well, fundamental airflow arrangements and computer fans are necessary for sufficient cooling. Fans play a vital part in airflow cooling for this reason. You should be familiar with CFM, sound frequencies, and the significance of high spinning speed.

In addition, dust might sometimes cause your system to overheat. Therefore, it is essential to regularly clean your computer. Also, if you are experiencing a problem with overheating, you should inspect the CPU and GPU thermals.

Does adding more fans than usual affect pc performance?

Adding more fans than typical could cause issues; adding a large number of fans will require a power supply, and if your power supply is inadequate, it will likely deplete some power from your graphics card or other components, which can negatively impact your computer’s performance.

Are 1000RPM fans powerful enough?

The majority of computer cooling fans have a typical rpm between 1300 and 1600; 1000RPM falls into the low bracket and has a negligible effect on performance. Fans at 1000 RPM are not more efficient than other standard cooling fans.
