PC Case Fans are one of the most important computer components and they are primarily responsible for ensuring proper airflow in your computer. Without them, the temperature inside your case can get high which can then increase the temperature of your major components i.e. CPU, graphics card, hard drive, memory, motherboard, etc. This may lead to damage and thermal throttling of the components, thereby reducing their performance and lifespan. PC case fans come in various sizes, models, speeds, and varieties from different brands and manufacturers. Some of them are higher in quality, and performance and have a longer lifespan.
Also, some of the computer fans can be very noisy and some of them are silent in operation. Generally, fans with higher RPM, low-quality bearing, and un-optimized design tend to be on the noisier side. Noisy fans can be very annoying as they make whining or grinding noises which is intolerable and frustrating to cope with. It also possesses a hindrance to your work. So, it is always better to use good quality silent PC fans in your case that can provide a great balance between performance and quieter operation. Yes, they may have a bit lower fan speed or RPM but still, they are very much effective in keeping your PC case cool because of their optimized design. Also, if you want to install more fans in your PC case then it is better to use quiet fans as their collective noise level will not add up to the point where they can drive you crazy.
The noise level of computer fans is measured in a unit called decibels, denoted by dBA. Below you can see the noise levels of different noise sources. You can see that any noise level between 10 dBA to 25 dBA is pretty quiet and can be easily tolerated by us without causing any disturbance in work. So, here in this post, I am going to list down the best quiet PC fans with noise level ratings below 25 dBA. These silent PC fans can be used as both exhaust and intake fans in computer cases. Also, some of these quiet fans have higher static pressure too and can be used on heatsinks, radiators, and in restricted spaces. You can use these quiet case fans in Gaming PC, HTPC, Video Editing PC, Workstation PC, Servers, or in Silent PC Cases for building a super-quiet PC.
| Noise Level (dBA) | Noise Source and Effect |
| 0 | Threshold of Human Hearing |
| 10 | Breathing (Barely Audible) |
| 20 | Whisper, Rustling leaves |
| 30 | Quiet rural area/residence |
| 40 | Raindrops, quiet Room |

Quiet Range for PC Case Fans -> 5 dBA to 24 dBA
Note: The unit that is used to measure fan airflow is CFM, which stands for cubic feet per minute and is the volume of the air (in cubic feet) moved by the fan in one minute. Higher the CFM value of the fan, the more air it will move in an open surrounding with no obstructions. On the other hand, the static pressure of a computer fan is measured in mmH2O, which is defined as the pressure exerted at the base of a column of water exactly 1 millimeter (mm) high. Higher the mmH2O rating of a fan, the higher its static pressure.

Best Silent PC Fans 120mm
Here are the best quiet 120mm fans for use in PC cases as an exhaust or intake fan and for use on heatsinks and radiators.
Noctua NF-S12A PWM Fan
Noctua makes one of the best PC fans in the business. Their fans offer great performance and they are also much quieter than the fans from other brands in the same league or competition. Here we have Noctua NF-S12A PWM Fan which is a Silent Series fan from Noctua having a 120mm form factor. The fan comes with Noctua’s proprietary SSO2 bearing which is known for its long-lasting life and quiet performance. This is a PWM fan and has a speed in the range of 300 to 1200 RPM. There are six fan blades with greater gaps between them for achieving higher airflow and quieter performance.
The fan generates an airflow of 63.27 CFM and static pressure of 1.19 mmH2O. It is almost super silent in operation with a maximum noise level rating of 17.8 dBA only. The fan also comes with anti-vibration rubber pads on all the corners to reduce vibrations and the noise generated by it. Due to its decent amount of static pressure and Anti-Stall Knobs, it can also be used on heatsinks and radiators. Other major features of this silent fan include Anti-Stall Knobs, AAO (Advanced Acoustic Optimisation), Inner Surface Microstructures, Metal Bearing Shell, and NE-FD1 PWM IC. The fan comes bundled with a Low Noise Adapter (L.N.A.), which you can use if you want it to be extra silent at the expense of rotational speed and performance. In my opinion, this is one of the best high-quality quiet fans that you can get. Highly Recommended by me.
P.S. – If you want a cheaper alternative then you can opt for Noctua NF-S12B redux-1200 PWM which is also a very good silent fan and has an 18.1 dBA noise level rating.

Arctic F14 Silent is a quiet case fan that uses a 3-pin connector and runs at speed of 800 RPM. The fan comes with fluid hydraulic bearing and generates airflow of 46 CFM which is quite decent for an 800 RPM. The noise level rating for this fan is 20.5 dBA or 0.08 Sone. The fan does lack anti-vibration rubber pads but still, it is quite a good silent performer and it does not exhibit vibrations because of its lower RPM. You can use this fan as both intake and exhaust fan but in my opinion, it is better to use it as an exhaust fan at the rear and top of the computer case. Overall, a decent 140mm quiet fan from a very respectable brand.

Just curious as to why this is not on your list. Low CFM but very quiet, 6.9 dB(A), at list as it’s listed.
Noctua NF-S12B REDUX 12V 700RPM 120mm Quiet Case Fan 6.9 dB(A)
This is for a DAW, quietness is paramount!
Will add this to the list. Thanks!
Silent wings have poor air flow if you compare then to cheaper pure wings… Of course dB goes higher cause of diffrent build. Of course i would add as well Noctua redux series if you don’t want pay extra bucks for unnecessary stuff. Did you have couguar fan on hands? It look only that good on paper…
