The copper water block has multi-channel internal structure that consists of thin 6-7 mm tall ribs.There is a layer of thick gray thermal interface already pre-applied onto the water block base surface. The fittings on the pump can be rotated as needed, which makes it fairly easy to install the water block onto the processor and prevents the tubes from kinking. The pump noise is claimed to be between 26 and 37 dBA, and its maximum power consumption shouldn’t exceed 3.1 W. However, we know that it is built with a ceramic bearing that should last at least 50,000 hours.
Moreover, there are threaded loops on each side of the radiator for attaching fans.The pump and water block form a single unit only 72x72x28 mm in size.īeneath the plastic cover there is a pump with unknown declared performance. Each tube is 11 m in external diameter and 330 mm long. Two fittings come out of the radiator and the flexible tubes are firmly pressed against them.
It consists of 9 flat channels about 1.5-2 mm thick and corrugated band soldered to it creating 1.5 mm wide cells. Nevertheless, the 3-year warranty from Antec should protect the users from any possible problems like that. And no matter what type and quality of anti-corrosion additives the coolant has, copper and aluminum form a galvanic pair, which will eventually lead to inevitable corrosion. I am sure that it will affect not only the cooling efficiency of the system but also its life span, because the system does include a copper water block. Unfortunately, the major downside of the radiator still remains – the entire thing is made of solid aluminum. The key difference between Antec KÜHLER H2O 920 and the previous 620 model is the twice as thick radiator – 49 mm instead of 27 mm: It consists of a radiator with fans and a pump with the processor water block connected to the radiator with two flexible tubes: The system is pre-filled with the coolant and sealed. Antec KÜHLER H2O 920 is built on Asetek 570LC platform that is why there is nothing principally new about its structure:
