be quiet! might not ring a bell for most non-European people, but for those who happen to live in this cornucopia of cultures and countries, you've probably seen their products. After releasing only air-cooled products, they have now released a line of water-cooled All-In-One sets called the SILENT LOOP: a push-pull 120mm radiator set, a 240mm radiator set and a 280mm radiator set.
All three feature copper radiators, copper blocks, a decoupled reverse-flow pump which is claimed to be less noisy and what seems like G1/4" threads with quality tubing.
Eteknix has reviewed the 280mm unit and had this to say:
be quiet! don’t get their name for the best cooling in the business, they get it for being quiet, ain’t that a shocker! The Silent Loop isn’t just quiet, it’s virtually silent and by far the quietest water cooler we’ve ever tested. To get good temperatures at such a low acoustic level just shows the quality of the components be quiet! has chosen for this cooler and that’s going to be a serious factor for anyone building a high-end and overclocked gaming system, who also wants their rig to be as quiet as possible.
Build quality is as good as it gets, as everything feels robust and has a good weight to it. The tubing is flexible, but feels very strong and comes fitted with premium quality screw mounts on both the pump and radiator ends. The Pure Wings 2 fans are already known to be a great quality component and we’ve proven that much today with their excellent performance. What really impresses the most, however, is how quiet the pump was. be quiet! are proud to shout about their pump design, but at the end of the day, it does the job, it makes very little noise and that’s what really matters to the consumer.
