The Best 120mm and 200mm Computer (PC) Case Cooling Fans

Keeping your computer cool at a low temperature is a very important action to carry out in order to ensure that all your computer components are working at their utmost performance without having to slacken due to the raise of heat level. That’s because high temperatures bring out the burning of the microscopic electrical circuits of which most, if not all, computer peripherals are made, and for that reason those peripherals have to diminish their performance in a pursuit to decrease the generated heat released out by them due processing data (the case of CPU and GPU) or transferring those data (the case of RAM, HDD and SSD).

The Importance Of Computer Case Fans

As has been said earlier, the high temperature has a devastating effect on computer components in the worst scenarios, but often, even if the temperature exceeds its recommended limit, its worst effect will only be decreasing the performance without harming the architecture of any part in the box. When those parts are in action they release lots of heat especially if the computer is put under heavy workloads for a long time. This should be a big concern for enthusiast video gamers, professional 3D graphics designers and video editors, and network server managers.

To work around this issue one needs to renew the confined hot hair inside the computer case by employing case fans that help to create an airflow inside the box by blowing the room-temperature air inside and pulling the hot air outside.

This technique will ensure that the heat generated by the computer parts will not accumulate to negatively impact the overall temperature, and consequently the performance, of your system, so that eventually it keeps running smoothly at its utmost.

It’s worth to be noted that it was tested and reported that if you would keep your PC case open you wouldn’t need more than the rear fan for an optimum cooling and you can totally dispense with case fans. But the drawback of this technique is the unpleasant appearance of the open computer case and the possibility of collecting more dust and dirt than if it is closed. After all it’s your own choice to decide which situation suits you better.

Types Of Computer Case Fans

There are different types of computer case fans available out there, and they are basically classified depending on the dimensions of these fans. The most common types of these fans are 120mm, which are small and consume low power, and 200mm which are large, pull more air than their siblings and consume higher power to run.

Choosing between fans depends primarily on the design of your case. Just check the measurements of the holes dedicated for fans before determining which type of fans works out for you.

The Best 120mm Case Cooling Fans

Noctua [NF-S12A PWM]

Product Description

The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimization) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling.

Basic Features

  • The NF-S12A features the third evolution of Noctua’s classic Straight Blade Design that achieves 10 cfm
  • The NF-S12A’s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan’s stall margin, that is even more versatile than its renowned predecessor.
  • Noctua’s AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctua’s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan’s performance/noise efficiency.
  • Noctua’s Stepped Inlet Design adds turbulence to the influx to facilitate the transition for laminar flow to turbulent flow, that reduces tonal intake noise, improves flow attachment, incur suction capacity, especially in space restricted environments.
  • Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
