Case fan guide

High-performance desktop PCs generally require one or more additional fans in addition to those already available in-house case Fans because the integrated components of the PC also generate a lot of heat. Fans for the housing are available in many different versions and with different performance. What to look for when buying one case Fans should be respected, explains the following guide in detail.

What does a case fan do?
The main task of a case fan is to remove the hot air from the PC case and that as fast as possible. This keeps the system components cool, which does not damage the system or slow it down. Waste heat gives off almost all components of a PC, in particular the CPU, the motherboard chipset, hard disk and the graphic card, Even if the PCeven already has its own fan, can one case Fans make sense. Especially gaming PCs with extremely high performance can hardly get one case Fans past. These are usually already installed in the housing. Later, if necessary, but still external case Fans to be built in. These are available with different rotational speeds, so that they can be selected according to individual requirements.

Which fan sizes are available?
As mentioned earlier, many different fan sizes are available. The most common sizes include 80, 120 and 140 mm up to 200 mm. This dimension is the diameter of the rotor blades. Basically, a large fan ensures greater air movement. The additional benefit of large fans is that they also rotate slower, making them quieter than small models. Most effective is a combination of different sized case fans. So you can be sure that no area comes from the housing too short.

What is the speed of case fans?
Slow case fans have speeds of 600, 800 to a maximum of 1,000 RPM. Models with a speed of 600 RPM are generally not recommended, as they have only a very low air flow. Effectively, the 120mm fans operate at 2,000 to 3,000 RPM or more. High-performance models deliver an air flow rate of around 140 m3 per hour in this segment. By comparison, case fans with less than 1,000 RPM generate about 30 m3 per hour. This in turn makes it clear that speed also has a big impact on the performance of a fan.

What to look for in the volume?
Of course, the built-in case fans should of course be as quiet as possible. Unfortunately, there are many models in this segment with a significant disturbing noise. The volume of a fan depends, among other things, on the design and the speed of rotation. Especially recommended are ball-bearing models, as they are very quiet. But even if the rotational speed is low, it can come to annoying clacking noises, namely if the construction is deficient. Also on the purchase should therefore necessarily be respected. In recent tests, for example, the Thermaltake Riing 14 LED Red and Noiseblocker Black Silent Pro PK-PS 140 models performed particularly well.

How to connect a case fan?
Case fans can be connected to the motherboard, at the power adapteror with an additional fan controller like an expansion card. For fans with 140 mm PWM, the rotation speed can be regulated by the user. If the chassis fan is connected to the motherboard, the power can be regulated automatically via the BIOS. A disadvantage here, however, is that motherboards usually offer only a few connection options for case fans. Since the power supply is already better equipped, which sometimes even can take over the control of the fan by means of a temperature measurement. This in turn makes it clear that there are many opportunities in this area, so that everyone should decide individually what is most effective.

Which construction method is recommended?
High-quality case fans usually have a sliding or ball-bearing, where favorable models are provided with a ceramic bearing. Ceramic models score with their longevity and become quieter over time as the ceramic bearing grinds in, so to speak.
