The Antec Kühler H20 620 arrives in a nicely designed box with the trademark company colours and a clean, high resolution image of the cooler on the front.
Inside, neatly arranged, are all the components. The pump and radiator assembly, a 120mm fan, install manual, mounting brackets and screws.
The manual is a fold out pamphlet, which I have to say was rather confusing in parts.
The Antec Kühler H20 620 Liquid Cooler ships with mounting brackets for both AMD and Nvidia platforms, as well as colour coded front mounted retention holders. The manual doesn't really detail this very well, especially as its printed in black and white and makes no mention of colour. AMD are green, and Intel are blue, in case you are wondering.
The Antec Kühler H20 620 has two connectors wired to the pump and the hoses connecting the pump to the radiator are thicker, soft rubber hoses rather than the smaller, stiff hoses normally associated with other coolers in this class. The finish and build quality is excellent and the shipping gives a high level of protection for the radiator which was perfect when we took it out of the box. Often we get little ‘nicks' and bends in the radiator array due to rough shipping and inadequate protection.
The hoses are soft and flexible and are about 13 inches long, making them about 2 inches longer than other coolers with a similar design. They are really easy to work with and the hoses are thicker than previous H70 hoses, expanded in size from 8.7mm to 10.8mm, meaning more liquid can flow through them.
The Antec Kühler H20 620 head is branded with the company and product name, and the contact head ships with a layer of quality thermal material preapplied. The pump has an extra three pin connector to control the coolers fan, and the swivel mounts and hoses are larger than others we have seen on Asetek sourced coolers.
Many would expect Antec to be using a standard four pin connector for PWM control but Antec are using a simple 3 pin head which we would assume contains wires for power and grounding.
