Comparison Deepcool AG400 ARGB Black vs Deepcool AG400 LED

The colour of the backlight installed in the cooling system.

See above for more details on the backlight itself. Also note here that in the illumination of modern cooling systems there is both one colour (most often red or blue, less often green, yellow, white or purple), and multi-colour systems such as RGB and ARGB. The choice of a single-colour backlight depends mainly on aesthetic preferences, but the last two varieties should be touched upon separately.

The basic principle of operation of both RGB and ARGB systems is the same: the design provides for a set of LEDs of three basic colours — red (Red), green (Green) and blue (Blue), and by changing the number and brightness of the included LEDs, you can not only intensity, but and tint of light. The difference between these options differs in functionality: RGB systems support a limited set of colours (usually up to one and a half dozen, or even less), while ARGB allows you to choose almost any shade from the entire available colour range. At the same time, both of them can support backlight synchronization (see below); in general, this function is not required for RGB and ARGB systems, but it is used almost exclusively in them.

Backlight synchronization technology, provided in the cooling system with built-in lighting (see above).

Synchronization itself allows you to "match" the cooling backlight with the backlight of other system components — the motherboard, processor, graphics card, case, keyboard, mouse, etc. Thanks to this matching, all components can change colour synchronously, turn on / off at the same time, etc. The specific features of the operation of such a backlight depend on the synchronization technology used, and, usually, each manufacturer has its own (Aura Sync for Asus, RGB Fusion for Gigabyte, etc.). The compatibility of the components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to collect components from the same manufacturer. However, among the cooling systems there are solutions of the multi compatibility format — compatible with several synchronization technologies at once; a specific compatibility list is usually indicated in the detailed specifications of such models.
