be quiet! is one of the most widely known hardware manufacturers in Germany and across Europe, with ranges including CPU cooling, chassis, and case fans. Adding to its range of CPU coolers, be quiet! has unveiled its latest series of AIO coolers, the Pure Loop. Available with multiple radiator sizes spanning from 120 mm to 360 mm, be quiet! looks to aggressively target enthusiasts and performance to keep things running nice and cool.

Back in 2016, be quiet! unleashed its first-ever series of AIOs, the Silent Loop. Fast forward four years from then, and be quiet! has opted for a different route, dropping Alphacool for its pump OEM, and opted for an undisclosed brand. The new Pure Loop AIO CPU coolers are available in four different sizes, 120, 240, 280, and 360 mm. 

The biggest change in design comes via the pump, with a new double decoupled pump. be quiet! claims this allows the AIO to operate quieter and with fewer vibrations than the previous Silent Loop series. Each of the models share the same 27 mm thick radiator, albeit in different sizes to accommodate the Pure Wings 2 PWM fans. The 120 mm comes with a single 120 mm fan, the 240 mm with two 120 mm fans, the 280 mm with two 140 mm fans, and the largest, the 360 mm with three 120 mm fans. 

The cold plate on the CPU block is nickel-coated copper which means users can use liquid metal thermal compound for better performance, although be quiet! does supply a small tube of its thermal paste in the accessories bundle. The block itself looks elegant and includes white LEDs surrounding the aluminum styled front cover, something more classical instead of RGB LEDs. Another 'cool' feature is the design allows users to top up the fluid with easy to access fill ports, meaning longevity is a big factor, with a supplemental bottle of fluid in the bundle. It does come pre-filled for users to install straight away.

Touching on the compatibility, be quiet! doesn't list the supported socket types, but it's likely to support AMD's AM4 socket, with support for the latest Intel LGA1200 as well as LGA115x sockets. be quiet! themselves recommend the 120 mm for users with AMD Ryzen 3 and Intel Core i3 processors, the 240 mm for Ryzen 5/Core i5, the 280 mm for Ryzen 7/Core i7, and the 360 mm for the high-performance Ryzen 9 and Intel Core i9 processors.

The expected release date for the be quiet! Pure Loop AIO liquid coolers is sometime in early October, with a competitive pricing structure. The 120 mm has an MSRP of $85, the 240 mm will cost $95, the 280 mm $105, with the 360 mm at a slightly higher price of $120.

    There's still some air in a CLC, and even if it shipped completely airless, over time it'll capture some air due to permeation.

    I wish Anandtech wouldn't propagate the misleading AIO naming.
    An 80mm AIO has an 80mm fan. A 120mm has a 120mm fan. But a 360 has three 120mm fans, which have a *third* of the cooling surface that a real 360mm fan/heat exchanger would have.
    At least mention this?

    This naming with water cooling radiators is pretty much industry standard now and anyone talking about PC cooling will understand them.

    They are simply measuring length, which is consistent across all AIOs, its not like there is a jump anywhere where the meaning changes.

    Yep, it's been the standard for well over a decade, as long as radiators-built-for-the-PC-WC-market has been a thing (prior to that, it was mostly repurposed car radiators). The assumption is that a radiator will be a single row of fans, and that any that are not (e.g. a 2x2 arrangement) will be specified as such due to their rarity.

    And I would like a product that is made in China, but put together somewhere else to say made in China.

    It's not 360mm².

    Dude it's been known that 360 aio is 120fans x3... It's advertised everywhere like this. Unless you're not from the tech community.
  • Gigaplex - Saturday, September 5, 2020 - link

    The number refers to the length, it's not a guarantee that it's a square shape. If you want a "real" 360, you need to define it as 360x360.

    lol, good shitpost!

    Still got a LONG way to go to be as quiet as the Zalman Reserator 1 v2. This unfortunately discontinued cooler was completely silent apart from a very quiet pump - no fans needed.
