Simple design may be boring for some
This Noctua fan is a balance of simplicity and quality. It’s a reinvention of a classic Noctua fan that can provide significant airflow and impressively low noise levels. At a quiet 18.1 dBA (even while putting out almost 60 cubic feet of air every minute) your PC will run quietly, reducing ambient noise in your work or play area.
The two-tone gray color means this one will blend right in with many PC setups, which is perfect for those who prefer substance over style. You can also make this fan even quieter by slowing it down (by lowering the voltage or using an optional low-noise adapter). The lower-voltage mode means the fan won’t spin over 1200 RPM, and if you really need to be as quiet as possible, you can pick up some optional Noctua anti-vibration mounts to put between the fan and your case.

Using a three-phase, six-pole motor, fluid dynamic bearings, and special mounts, you get fewer vibrations and lower power consumption for less noisy operation. The fan clocks in at 13.6 dBA in its quietest operation, landing between a whisper and someone calmly breathing, which makes it virtually inaudible.
The Silent Wings 4 may be quiet, but it’s still powerful. The 140mm option delivers airflow up to 87.16 CFM thanks to the funnel-shaped air outlets on the fan frame, so this fan pairs perfectly with the best PC cases for airflow. You also aren’t limited to the 3-pin 140mm fan, as it also comes in a 120mm size or with a 4-pin PWM, ensuring you find the best fit for your build.

Larger 30mm width
If you’re building a gaming PC with water cooling, you’ll need a fan that can deliver a high static pressure so it doesn’t struggle to push air through a constricting radiator fin array, liquid CPU coolers, or grills. The Phanteks T30-120 120mm fan can deliver 3.3 mmH2O of static pressure and 67 CFM airflow, which is great for this. A switch also lets you select three different operating modes without downloading any software.
NOTE: the Phanteks T30-120 is slightly bigger than standard fans, so make sure you have enough room for its 30mm width before picking this one up.
10. Noctua NF-A12x15
Best Low-Profile PC Fan
Noctua NF-A12x15
A thinner PC fan ideal for tighter spaces that still produces plenty of airflow to keep your PC's internals cool.

Diameter

Airflow
55.4 CFM
Noise
23.9 dBA
LEDs
None
Connector
4-pin
Dimensions
4.7" x 4.7" x 0.59"
PROS
Keeps compact size without compromising performance
Anti-vibration mounts included to help with noise
CONS
Color scheme isn’t for everyone
The Noctua NF-A12x15 fan is nearly half as thick as many of the other fans on this list, making it ideal for cases that are tight on space. It's effectively the slimmer sibling of the Noctua NF-A12x25.
Even better, it doesn’t sacrifice performance for its small size. You still get a solid 55 CFM of airflow and, at that level, it only produces 23.9dBA of noise. Even though 23.9 is very quiet, you can use the included Low-Noise Adapter, which sacrifices some airflow to bring the noise down to an incredibly quiet 16.8dBA. Anti-vibration mounts are also included and can prevent rattle for even quieter operation.

PC Fans FAQ
Which fans are most important in a PC?
To prevent your hardware from throttling and overheating, a front intake fan and a rear exhaust fan are the most detrimental. A front intake fan ensures that fresh cool air flows over your PC’s components, and it can be helpful to have more than one if you’ve got the space. A rear exhaust helps to expel heat out of the case, while another exhaust fan at the top of the case, if it has ventilation and is away from intake fans, is useful for removing the rising hot air. It’s also possible to install side-mounted fans, which should usually be in an intake position, but as a general rule of thumb, it’s best to have air flowing front to back.
What to Look for in a PC Fan
There are a few things you should look for when picking out PC fans.
First, make sure you measure your PC case to make sure the fan you want will fit in the mounts your case has. Standard sizes range from 80mm to 250mm, and you’ll generally need larger fans for larger PC cases, since they’ll need to move more air. 120mm and 140mm also (normally) have the same mount size, and larger fans are generally quieter and move more air.
Speaking of moving air, the stat you want to keep your eyes out for is “CFM,” which stands for “cubic feet per minute.” The higher the number, the more air the fan can move, the better. That said, fans with the highest CFM also tend to be loudest.
Fan noise (like everything else) is measured in decibels (or dBA), and the smaller the number, the quieter the fan. If noise is important, prioritize a fan with a low decibel level, or one with several modes you can switch between, so you’ll have quiet options without sacrificing performance when you need it. Also, as we said before, larger fans can spin more slowly, and therefore more quietly, while still moving lots of air, so it’s probably a good idea to get the largest fans your case can hold.
You’ll also need to check your pins and connector styles. Four-pin connectors on PWM (pulse width modulation) motors are speed-adjustable and therefore, more energy-efficient, while three-pin connectors generally control DC motors (although adapters are available).
Another thing to keep in mind is that fans are generally specialized for one of two things. Either they are optimized to move a high volume of air (generally with large blades and high RPM) or generate high static pressure. High-airflow fans can run into problems when used in a case with restricted airflow – that’s what high static pressure fans are for.
Although nicer fans still aren’t that expensive (relative to other PC components), you still get what you pay for. Ball bearings, often found in the least expensive fans, tend to fail more often, while sleeve bearings are a step up in quality and longevity, and fluid bearings tend to be the most reliable, with the longest lifespans. Unlike most PC components, fans are mechanical systems meant to run continuously for years, so get good ones!
RGB light is all the rage, whether you are looking at area lighting, LED strips, graphics cards, case lights, and more. Fans are no different, and because they naturally move during operation, many fans are incorporating light systems. Whether you want a single color, a small variety of colors to choose from, or a 16.7 million-color LED system that can even display moving images like GIFs, there are choices out there for you. Enjoy and stay cool!
