Socket

Socket - processor connector - 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 mounting place for the cooling system. So, when purchasing a processor cooling system separately, it is worth making sure that it is compatible with the socket. Nowadays, solutions are mainly produced 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.

Pump size

The dimensions of the pump that the water cooling system is equipped with.

Most often, this parameter is indicated for all three dimensions: length, width and thickness (height). These dimensions determine two points: the space required to install the pump, and the diameter of its working part. With the first, everything is quite obvious; we only note that in some systems the pump simultaneously plays the role of a water block and is installed directly on the cooled component of the system, and it is there that there should be enough space. The diameter approximately corresponds to the length and width of the pump (or the smaller of these dimensions if they are not the same — for example, 55 mm in the model 60x55x43 mm). Some operating features depend on this parameter. So, the large diameter of the pump allows you to achieve the required performance at a relatively low rotation speed; the latter, in turn, reduces the noise level and increases the overall reliability of the structure. On the other hand, a large pump costs more and takes up more space.

Pump power source

Type of power connector for the water pump.

3-pin. The three-pin power connector on older motherboards does not allow you to control the speed of the water pump motor in liquid cooling systems. At the same time, the pump always works in the maximum performance mode. Fresh "motherboards" are able to change the voltage on such connectors, thereby providing a change in engine speed.

4-pin. When using a 4pin power connector, it is supposed to control the speed of the pump motor using pulse-width modulation. A voltage of 12 V is applied to it with pulses. By changing the duration of the pulses, you can accurately set the speed of the water pump motor.

SATA. The SATA power connector will come in handy if all free 3pin and 4pin connectors are occupied on the motherboard.

Display

Remote or built -in information display in the design of the cooling system. The screen is used to display information about temperature, fan speed, voltage, etc. In advanced implementations, the display can be used to control cooling parameters to ensure optimal system performance and stability.
