To read and control the temperature or other values of his water cooling system, two essential items are needed. Sensors that are placed directly at the points to be monitored, and a control unit or special software that reads and monitors the values. In addition to temperature, the fill level, differential pressure, and water flow in a water cooling system can be measured. Good control units enable the monitoring of temperature sensors in a measurement range of 0 - 100°, as well as free control and monitoring of radiator fans with individual parameters.
If desired, some control systems can also connect lighting modules and create various lighting effects. Control is either via regulators or buttons on the control unit itself or via software - for this, the control unit usually needs to be connected to the computer via USB. Normally, the control units are connected to the power supply via a 4-pin connector.
