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.

    That's actually a good idea. They can package a pump on the hoses that will then dampen vibrations and then people will feel as though the cooler is higher quality because the pump isn't transferring those vibrations to the chassis via metal to metal contacts. They can get away with going cheaper on the pump as well since it does not have to fit within the dimensions of a CPU socket. Interesting.

    It also gets you away from being sued by Asetek.

    Immediately raised an eyebrow when I saw that as well. Huh. I have no idea if it will work better or worse than the pump being in the block, on the block, or in the radiator, but I am certainly interested to see how it fares.

    There are so many advantages to removing the pump from the block, frankly I'm surprised they are able to make such a radical design change and still keep these things reasonably priced.

    the prices actually seem very reasonable

    We'll have to wait for a review to see how well the decoupled pump works.

    What's the radiator made out of? Their previous AIO cooler had a copper radiator instead of aluminum, which should have reduced the risk of corrosion. It's a shame that they discontinued it, and that so few (if any) companies make an AIO with a copper radiator.

    So what about this radiator? Copper or aluminum?
  • Samus - Friday, September 4, 2020 - link

    There's no risk to corrosion of aluminum radiators in a closed loop system. The fluid is treated with an anti-corrosion agent and a friction modifier to act as a lubricant and improve heat transfer in virtually all closed loop coolers that include any sort of warranty, because just putting water in them would cause rapid failure to the ceramic bearings in the pump let alone the corrosion concern.

    Yeah, most CLCs with mixed metals do just fine... except enermax's liqtech CLC

    All AiO coolers perform about the same with the same fans and size, Except for the few with copper Radiators. They are just way better at dispersing heat and that is the limiting factor apparently.
    Can't believe the copper ones, even if they are slightly more expensive are not sold in 90% of the cases.
    In a closed loop, corrosion is not really happening. You need oxygen input to corrode.
