Comparison ARCTIC Liquid Freezer II 360 RGB vs ARCTIC Liquid Freezer II 360 A-RGB

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.

Socket type - socket for CPU - with which the corresponding cooling system is compatible.

Different sockets differ not only in compatibility with a particular CPU, but also in the configuration of the seat for the cooling system. So, when purchasing a processor cooling system separately, you should make sure that it is compatible with the socket. Nowadays, solutions are produced mainly for the following types of sockets: AMD AM2/AM3/FM1/FM2, AMD AM4, AMD AM5, AMD TR4/TRX4, Intel 775, Intel 1150, Intel 1155/1156, Intel 1366, Intel 2011/2011 v3, Intel 2066, Intel 1151/1151 v2, Intel 1200, Intel 1700.
