Another option besides conventional air cooling is cooling with water. The circuit here usually consists of a pump, radiator, expansion tank, fans and a cooling block that sits on the surface to be cooled – all connected by hoses or rigid piping.
Fluorescent liquids are already obsolete, and RGB is also finding its way here. Phanteks supplies with the Glacier series cooling blocks for almost every CPU socket, but also for graphics cards. Matching Pumps are available from Aqua Computer, for example, which not only have a discreetly chic ring of bright colors, but also a black and white LCD. Values such as water temperature or flow rate can be read from this LCD.
Transparent compensation tanks provide a direct view of the coolant and are a highlight even without lighting. RGB LEDs increase this effect and are already installed in some models. Depending on the type, they are compatible with almost all mainboard header or control unit standards.
The connecting hoses themselves are not yet on the market in any RGB-capable variant, but in this case special fittings (connecting link between hose and screw connection) can be used. Raijintek covers with the PELIAS RGB series covers exactly this niche. The fittings can be controlled either by remote control or directly via the motherboard and software.
The lighting can be further optimised by various additives in the cooling water for example with white or UV-active colour.
Radiators are made of copper or aluminium. Integrating LEDs here would be an elaborate process – but here the entire range of colourful fans is available, which can be placed on the radiator and put it in the right light.
In addition to the custom-built water cooling systems, there is also a series complete systems. These offer the advantage that the individual components are usually optimally matched to each other and the planning and installation effort can be reduced to a minimum.
