Glossary
Fans
In modern models, 1 or 2 fans are installed at a minimum, and in more advanced models this number can reach 4. It makes no sense to bet anymore, because. the area of the cooling system in this case may be larger than the area of the bottom surface of even the largest laptop. The more fans provided, the more intense the heat removal and the higher the efficiency of the cooling system (ceteris paribus, of course). On the other hand, the noise level increases noticeably, and there are “multi-fan” stands, respectively.
The diameter of the fans also plays an important role. The larger the fan, the more advanced it is considered: a large diameter allows you to create an intense airflow at relatively low speeds, which reduces the noise level compared to smaller options. On the other hand, the large size also affects the cost accordingly.

Max. RPM
The highest rotational speed of the fans provided in the active cooling system of the stand (see above).
Rotation speed is one of the parameters that directly affects efficiency: the faster the fan, the more powerful airflow it creates and the more heat is removed. At the same time, only fans of the same diameter can be directly compared by speed. In addition, high rotation speed increases the noise level; therefore, comparatively slow but large fans are considered more advanced than small and fast ones with the same performance (see "Airflow").

Noise level
The maximum noise level produced by the stand during operation. This parameter is relevant only for models equipped with active cooling (see above) — in fact, this function is the only source of noise.
The lower this indicator, the more comfortable the use of the stand will be and the better it will be suitable for situations in which silence is important (for example, for working late at night when others are sleeping). At the same time, even in the loudest models, it usually does not exceed 40 dB — this is comparable to the noise of leaves on a tree in a light breeze; and cooling systems in many laptops can make more noise. Therefore, paying close attention to quiet laptop stands is only worth it if you are using an extremely quiet laptop and do not want to lose this advantage.

Backlight
Presence of a backlighting system in the stand design. Typically, this function is purely decorative: it doesn't affect functionality, but it does give the product a stylish appearance.
The color of the backlighting will be useful for those who want to match the stand with the laptop design or the computer desk decor.
Note that the ability to change the color is usually not provided in this case. So if the specifications list several options — for example, blue / green / red — it means that this model comes in several versions, differing by backlight color.
