I have tried many compact water-cooling systems and now try this out. The 80i is made from CoolIT, the pump is larger and more stable than that of built Asetek. Here is no rattling heard, it rotates at 2200 rpm, and can also be turned down without any problems. The tubes are thick and the internal diameter is greater = more throughput. The included software for monitoring and controlling the connected fans, as well as adjusting the lighting of the logo, not worked right away. Also, the internal USB port is not always recognized. Finally, after updating the firmware but everything worked. Since the 2 fan but still too loud I have only one Nonoxia FX EVO PWM 1000rpm fan connected, which is controlled by the MB bios. IDL temperature only 32 degrees, full load at 42-44 degrees. The volume is at max. 0.6 sone. A cooling system that gives pleasure (apart from the written inadequacies).
