Discover the Best PC Fans for Powerful Cooling and Quiet Operation
With few exceptions, almost every PC system requires active cooling. Active means that fans are responsible for cooling the computer or individual components within the system. The fans generate airflow through the case and/or push cool air through the cooler fins, where the air absorbs and transports the heat from the component to be cooled (e.g., processor or graphics card). Typically, airflow in a PC is directed from the front bottom to the rear top, or it follows the natural thermal convection from bottom to top. For this purpose, most PC cases, especially tower cases, have various fan mounting slots.
The Right PC Fan for the Necessary Airflow
The case slots can accommodate different fan sizes depending on the model, with each size having its strengths and weaknesses:
- PC fans with 80 mm and 92 mm are very flexible due to their small size. Therefore, they are found not only in smaller cases (such as HTPCs and cubes) but also in power supplies or on graphics card coolers.
- Fans with 120 mm or 140 mm rotors are the most common. They combine good airflow/output (measured in m³/h or CFM) with an acceptable noise level/loudness (in dB(A) or Sone) because they do not need to spin as fast as smaller fans (speed in RPM).
- Rotors of 200 mm and larger or particularly thick turbines with frame widths over 25 mm are considered exotic and do not fit in every case. These large fans move a lot of air at low speeds.
- Regardless of the size of the PC fan, some fans are optimized for high static pressure and are therefore ideal for use on radiators.
In addition to 3-pin fans, 4-pin PWM fans are also widespread, automatically controlled by the motherboard, while for 3-pin fans, a fan controller or voltage adapter can be used. Additionally, illuminated LED fans are very popular in the modding scene and among gamers. Digital addressable RGB fans are particularly common here. Nowadays, there are even fans with LCDs in the hub that display speed, temperature, or other system information.
