The radiator from the Stingray STG-100 kit is similar to the radiators of many other off-the-shelf liquid cooling systems. This dual-pass aluminum radiator with a 120mm fan has long proved its worth in desktop computers.
The dimensions of the radiator are 202 x 136.6 x 52mm. A quiet 12V cooler (120x120x25mm) is installed on it; it rotates at a speed of about 1600rpm. The cooler is connected to the mainboard and reports speed to the hardware monitoring system.
The speed is low, so the fan is quiet. According to the specification, the level of noise from this fan is not higher than 26dB. The fan runs on frictionless bearings and boasts high reliability as a result.
The radiator and fan come already assembled into a single unit. The manufacturer implies that you hang it on the outside of the back panel of your system case. There are screw-holes in the radiator that allow fastening it instead of an 80, 92 or 120mm system fan.
