PC Case Fans

A powerful fan should be a part of every PC case, whether it has high-end gaming or energy-saving components. This is because PC case fans ensure the proper airflow and thus the cooling of the entire computer. But how do I choose the right PC case fan for my device? Here is some advice.

The Most Important Parameters of PC Case Fans

Each PC case fan has several important parameters that you should consider when choosing one. These are mainly the size of the fan itself, its speed, its noise level and its airflow.

What Size Should PC Case Fans Be?

PC case fans are available in many sizes. The most popular fans are the 120mm and 140mm variants, but smaller or larger fans are not unusual. What size will be perfect for you?

The Advantages of Small PC Case Fans

  • The advantage may be the lower purchase price of a small fan.
  • The small dimensions guarantee compatibility with compact enclosures.

Advantages of Larger PC Case Fans

  • Large fans require lower speeds for the same airflow than their more compact counterparts.
  • Thanks to larger blades and lower speeds, large PC fans are also quieter.

The RPM is an Important Parameter of PC Case Fans

Each PC case fan has a specified minimum and a maximum number of revolutions per minute (RPM). Some models offer the user the possibility to control the speed. In this case, it's up to you whether you prefer power or a quiet operation. Take a look at speed-controlled fans.

Smart fan with speed control

Fan speed control can be automatic or manual. Always make sure that the model you choose supports the control. Motherboards with a voltage adjustment function offer the possibility to control unsupported fans.

Other Features of PC Case Fans

When choosing a new PC case fan, consider a few other features and functions that affect cooling performance, noise levels and a few other aspects of daily use.

  • The PWM fan allows the user to control the speed (RPM) at will.
  • Maximum TDP refers to how much heat the fan can dissipate. Processors and graphics cards also have this parameter.
  • The bearing type indicates the way the blades are attached to the centre of the fan. The most common systems are HBS, SSO2 or FDB.
  • Backlit PC case fans can glow in different colours. Some support a single colour and others dazzle with the entire RGB spectrum.

Do you need a whole set of PC case fans? Do not buy them individually. Take a look at convenient sets.

PC Case Fans with RGB Backlighting - Make your PC Stand Out

PC case fans with RGB backlighting support more than 16 million colours and shades. So your computer can really play with all the colours. When combined with a transparent cabinet, you can create a true work of art.

Wondering whether to choose a 5V, 12V or perhaps 24V PC case fan? Choose them in the clear category of Fans by Voltage.

Why Get a Silent PC Case Fan?

Do you dislike a lot of noise around you? Then a silent PC case fan is exactly what you need. These coolers boast high performance and minimal noise, so you will hardly notice them spinning. Take a look at Quiet Fans.
