Fans total
The
more fans provided in the design, other things being equal, the more intense the cooling will be and the more powerful (and, accordingly, “hot”) hardware can be placed in the case without the risk of overheating. For everyday tasks, a case with
one,
two or
three factory fans is enough. At the same time, when comparing, it is worth considering not only the number, but also the performance characteristics of the fans (diameter, speed). Also note that there are
cases without fans on the market with free space for fans, which allows, if necessary, to supplement the cooling system and improve its performance.
Fans (front)
The number of fan slots
on the front of the case, and the size of the fans these slots are designed for. The presence of the fans themselves in the kit should be specified separately.
The larger the fan, the more advanced it is considered: a large diameter allows you to work efficiently at relatively low speeds, which reduces the noise level and energy consumption. Case fans are available in several standard diameters; specifically for the front panel, the size
up to 92 mm is considered relatively small,
120 mm — medium,
140 mm — large, and in the most advanced solutions, fans of
180 mm or even more can be installed.
Also note that most often the holes for installing fans are designed for one specific size, however, there are also “multi-size” seats, for 2-3 options. Moreover, these options may differ both in diameter and in quantity: for example, it may be possible to install two 140 mm fans or three 120 mm fans.
Fan mounts total
The total number of places for installing fans provided in the chassis design.
The more performant the system, the more components it includes — the more powerful cooling it will need; therefore, the number of places for fans, usually, is directly related to the size and purpose of the case. It is also worth considering that with the same number, the installation location of individual fans may be different — behind, on the side, on top, etc.
Dust filter
The presence of a special filter in the housing to prevent dust from entering. Without such a filter, dust settles on the system elements; Radiators are especially susceptible to this; they also lose their efficiency by becoming clogged with dust. If you have
a dust filter, you have to clean not the “filling” of the PC, but the filter element itself, which is much simpler and more convenient.
Compartments for dust filters can be located on
the front panel of the case,
back,
bottom,
top, or
in the side walls. There are also case models with several technological niches for installing dust filters - the combined version assumes the presence of such compartments on several sides of the case at once.
Integrated hub
A hub in a computer case for connecting fan and backlight control systems. Depending on the implementation, the
complete hub can be installed inside the case or placed on its outer panel. Often, a remote control with an infrared transmitter is attached to the hub to control the "turntables" and decorative lighting of the "insides" of the case.
Fan controler
The ability to manually control the rotation speed of the fans installed in the case.
This function allows you to adjust the operation of the fans to the specific situation. For example, in cool weather with a light load, you can reduce the speed (or even turn off the fan altogether), reducing power consumption and noise level, and increase it when starting a demanding game. Also note that there are software tools that allow you to automatically adjust the speed of the fans; so that instead of manual control, this function can be entrusted to automation.
The fan control system is usually equipped with the most advanced case models.
USB 3.2 gen1
The number of native USB 3.2 gen1 connectors (previously labeled as USB 3.1 gen1 and
USB 3.0) provided in the case.
Such connectors are usually located on the front side (for more details, see "Location"). They are most convenient for peripherals that need to be connected and disconnected often — for example, "flash drives" (for permanently connected devices, it is more convenient to use the motherboard connectors displayed on the rear panel). Specifically, the USB 3.2 gen1 standard has replaced the USB 2.0 described above, it provides 10 times the data transfer rate (up to 4.8 Gbps) and higher power supply, while USB 2.0 peripherals can also be connected to such connectors .
It is worth remembering that for normal operation of ports, their number and version must correspond to the capabilities of the motherboard.
Side panel window
The presence of
a viewing window on the side panel of the case, allowing you to see the “filling” without opening the case. It gives the case a stylish appearance; in addition, it allows you to install a lighting system inside, which is appreciated by gamers compared to
case models without a window.
The materials for manufacturing the windows on the side panel are:
- Acrylic. Acrylic or plexiglass is an inexpensive material of relatively light weight, which, however, actively collects scratches and can be deformed when exposed to high temperatures.
- Strained glass. Tempered glass panels have excellent transparency, are resistant to scratches and are easy to clean from dirt. At the same time, they weigh a lot and can break to pieces if not handled carefully.
- Metal grid. Wire mesh is a simple type of window material used on the side panel of a cabinet. It allows air to pass through and provides additional heat removal from the internal components of the system unit; dust can leak through the mesh overnight.
