be quiet! Silent Loop AIO liquid coolers hum along quietly

be quiet! is showing off its Silent Loop series of all-in-one CLCs. Closed-loop coolers have been rising in popularity in the last few years, and the German PC component vendor is getting its feet wet with its first product aimed at this market.

The Silent Loop CLCs attempt to keep noise levels down by using a "decoupled reverse-flow" pump design. be quiet! says the pump speed can go as low as 2,200 RPM, generating less vibration and noise than other AIO coolers. And while the radiator is painted black, it's made completely of copper, as is the base. The cold plate for the cooling unit is nickel-plated, which be quiet! says will help cooling performance when using liquid metal-based thermal compounds.

For airflow, the series makes use of be quiet's Pure Wings 2 fans. In an unusual step, the company also includes a refill port so that users can top off the system's coolant. The Silent Loop is available in three models: a 280-mm model with dual 140-mm fans, a 240-mm with dual 120-mm fans, and a 120-mm model that just has one fan and a smaller radiator.

There's a possibility that that the Silent Loop won't be making it overseas. Asetek owns patents on the AIO style of liquid coolers in the United States, and it's sued companies like Cooler Master and CoolIt Systems over infringement of those patents in the past. If you're in Europe, however, the Silent Loop series is available now at 150€ ($168) for the 280-mm model, 130€ (or $146) for the 240-mm version, and 110€ ($123) for the smaller 120-mm CLC.

    I have the NZXT Kraken X61, 280mm AIO radiator, the pump in that is already virtually silent (used to have an H100 which was not). It’s quite a bit cheaper, $115 on Newegg right now, I got mine a year or two back for about $130 IIRC.

    It get’s the Chrispy_ seal of approval for not mixing metals.

    Outright performance isn’t really the point of AIO loops, it’s about getting a healthy overclock without having to use high-rpms on the fan(s). Anyone considering extreme overclocks will want to pick a stronger pump, larger diameter tubing and probably a waterblock that costs as much as a whole AIO by itself. These things are built down to a price, not up to a specification – and as long as you’re aware of the difference, they are absolutely fine.

    Your German colleagues praised the cooler for its silent pump, although the cooling performance when using their testing fans was average for liquid coolers

    It looks nice enough, I personally am not a fan of the coil around the tubing and I wish they chose something that didn’t look like an extended bendy straw
