Static pressure
The maximum static air pressure generated by the fan during operation.
This parameter is measured as follows: if the fan is installed on a blind pipe, from which there is no air outlet, and turned on for blowing, then the pressure reached in the pipe will correspond to the static one. In fact, this parameter determines the overall efficiency of the fan: the higher the static pressure (ceteris paribus), the easier it is for the fan to “push” the required amount of air through a space with high resistance, for example, through narrow slots of a radiator or through a case full of components.
Also, this parameter is used for some specific calculations, however, these calculations are quite complex and, usually, are not necessary for an ordinary user — they are associated with nuances that are relevant mainly for computer enthusiasts. You can read more about this in special sources.
Socket
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.
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 rotation speed
The speed at which the working part of the pump rotates, which is nominally provided in the water cooling system.
High speed, on the one hand, has a positive effect on performance, on the other hand, it increases the noise level and reduces the time between failures. Therefore, with the same performance, relatively “slow” pumps are considered more advanced, in which the necessary pumping volumes are achieved due to the large diameter of the working part, and not due to speed.
