Building a PC is more accessible than ever, and many people tend to lean toward customizable options as personal design preferences can range from form-over-function builds to those that are built around raw performance. However, as CPUs and GPUs continue to grow more demanding in their power requirements (and subsequent heat generation), it does warrant the need for more adequate cooling options to keep things running smoothly and at peak performance.
The longevity of a PC directly depends on the operating temperatures of its components. As a rule of thumb, running cooler is always better. While most CPUs and GPUs can easily take a beating at about 70-90 degrees Celsius, with temperatures well within design ratings, higher temps can directly impede their reliability over time. Running at higher temps can also prevent a PC from reaching peak performance as the system will throttle to prevent further spikes in temperature.
The Best CPU Coolers in 2024
Modern CPUs often require powerful and sustained cooling to maximize their overclocked performance. Here are some of The Best War Games's best picks!
Given this, PC cooling fans are always a welcome addition to most high-end computers, gaming rigs, and workstations that can benefit from the lower temperatures inside the case. Thanks to extensive experience with PC building, the The Best War Games team can guide users when it comes to which fans they should get for their gaming PC, focusing on performance, noise, and lighting (but not necessarily in that order).
What to Look for in a Gaming PC Case Fan
Gaming PCs tend to use case fans for both aesthetics and functionality, allowing users to not only make their PCs more visually appealing but to also maintain thermals, ensuring optimal performance. In the age of letting boost clocks dictate the performance of most new PC hardware solutions, being thermally tied down by components that increasingly push temperature limits is something many gamers want to avoid.
When considering a case fan for a gaming PC, players should consider the following factors:
- Maximum Airflow (In CFM)
- Noise During Operation (In DB)
- RGB Lighting (Brightness, number of LEDs, area covered)
- PWM Support (Allowing a motherboard to dictate fan speeds)
- Maximum RPM (Max fan speed)
- Cable Management Solutions (Wired vs daisy-chained fan sets)
- Custom RGB Controllers (One-stop fan and lighting control solutions)

Performance numbers aside, the Noctua NF-A12x25 PWM fans may leave gamers wanting more in terms of design and lighting. There is no RGB lighting and these fans do not come in three packs. This can make them a costly investment if gamers are planning to go the all-Noctua route and purchase each fan individually.
Finding the Best Gaming PC Case Fan
The different aspects of gaming PC case fans can be sorted into three categories:
Performance
The performance category can include the specifications of a case fan including maximum airflow, noise during operation, PWM support, and maximum RPM. The maximum airflow is calculated in CFM or cubic feet per minute. It is essentially the volume (in cubic feet) of air that passes by a stationary point in one minute. The higher the CFM, the more air the fan can move, resulting in better cooling, but it comes at the cost of noise. The noise factor is measured in dB or decibels and the higher the dB, the more noise a particular fan will make. Larger fans can move more air but also make more noise. When it comes to noise, there are a few other things to keep in mind, such as the number of fans, case design, and the location of the gaming PC.
PWM support is what allows the fan speeds to be controlled via the motherboard. This means the speed at which the fans will spin is determined by how hot the components of the gaming PC are. It also allows for more granular control of the fans. Lastly, maximum RPM is the top speed of the fan, and typically, 1500 to 2000 RPM is considered standard operation when it comes to gaming PCs. But again, it should be noted that higher speeds will result in louder operation, and fans that can deliver high RPM at low noise levels are considered to be the best.
Lighting
Most gaming PC fans these days come with some kind of RGB lighting that can be controlled via software. Corsair, Lian Li, Cooler Master, and Thermaltake are some of the manufacturers that offer case fans with RGB lighting. With the rise of gaming PC cases with tempered glass sides and front panels, providing unrestricted views of the internal components, manufacturers have been implementing RGB lights in fans. The lighting does not add to the performance of the fans but improves the aesthetic appeal of the gaming PC. This also means that additional software will need to be installed on the PC. Most manufacturers have a single software that allows gamers to manage all the parameters, including the lighting on their components. Furthermore, some case fans for PC gaming come with RGB or ARGB controllers that take all the RGB cables from the fans and convert them into a single cable that connects to the motherboard.
Connection/ cable management
Gaming PC case fans typically only need one power cable connected to the motherboard. While there are a limited number of FAN headers on motherboards, the total number of fans can exceed the total number of headers using fan hubs. Regardless, one fan comes with one cable that needs to be connected to the motherboard, but with the era of RGB lights in fans, there is an extra cable that needs to be managed within the PC case. These days, several manufacturers have been offering the ability to daisy-chain fans i.e. Connect multiple fans and then have a single cable for power going to the motherboard, for example, the Lian Li UNI FAN SL-INFINITY. This not only makes the installation process a lot easier, it also makes cable management a breeze. Instead of having to route and hide two cables per fan, gamers only need to deal with two cables for three or even four fans.
Other Considerations and Upgrades
Those who have already taken their pick of PC case fans from the list above should head over to our comprehensive guide on which PC cases are the best in class. If building a PC is too much of a hassle, or having a professional build would be preferable, users should consider our detailed guide about which prebuilt PCs would be the best to purchase for gaming in 2024.
FAQ
Q: What is the standard PC case fan dimension?
The standard PC case fan dimension is 120 mm. While 140 mm and 200 mm options are also popular, the bulk of gaming PCs support the 120 mm configuration as a staple. This is also reflected in the choices of CPU coolers and radiators that come in the 120 mm, 240 mm, and 360 mm configurations of late, all of which are a multiple of the 120 mm cooling fan specification.
Q: Does RGB lighting affect PC fan performance?
No, RGB lighting does not affect fan performance positively or negatively. Most RGB lighting on PC case fans comes from the 5-volt rail, which is independent of the fans that rely on the 12-volt rail for power.
Q: Are high-end PC case fans worth it?
Most PC case fans can do the job just fine. The Best War Games has listed the case fans that are the best-in-class, but generally paying more ensures better quality fans that have better airflow, aesthetics, lower noise, and excellent durability.
