Be quiet! is a German manufacturer that mainly produces computer cases, power supply units (PSUs) and cooling-related products. As the company name suggests, their products are designed with a special emphasis on quiet operation. The companies are no strangers to North American markets, slowly but steadily increasing their presence in recent years. They are, in fact, one of the few EU-based companies that managed to maintain a foothold in the North American market during the pandemic.
Looking at their overall product offering, Be quiet! is a fairly typical manufacturer of computer peripherals. The company is perhaps best known for its impressive power line, and they also offer holsters, fans and refrigerators. These days, of course, this extends to all-in-one (AIO) CPU liquid coolers, with their cooler from the Pure Loop family.
True to your design ethos, Be quiet! has built the Pure Loop series to work with as little noise as possible. And unlike some other players in this space, the company is not trying to make Pure Loop a niche, premium (read: expensive) offer; so refrigerators are competitively priced for the mass market. All in all, the Pure Loop series consists of four coolers, ranging from 120 mm and 240 mm to sizes up to 280 mm and 360 mm. All four coolers are, as is usually the case, practically identical, with the exception of the size of the radiator.
For today’s review, we take a look at the 280mm version of the Pure Loop AIO cooler, which is the second largest offered by the company and seems to be the most popular size for AIO coolers at the moment.
Packaging and package
The Pure Loop refrigerator comes in a solid cardboard box which, along with customized internal inserts, provides excellent transport protection. It’s aesthetically dark and muted, much like almost all Be Quiet! Boxes, but with plenty of information about the cooler located on the side and back of the box.
The items associated with the Pure Loop cooler are pretty basic. Inside the box we found the necessary hardware for mounting the sockets, a small syringe with a little thermal grease, adapters to power the fans and a few cable ties.
A surprising addition here is a bottle of coolant, which is very rare for an AIO cooler. As we will see in our technical review, the Pure Loop is not a traditional closed-loop refrigerator, so users can manually refill and replace its refrigerant.
The fans supplied with the Pure Loop cooler are Be Quiet! -These Pure Wings 2 PWM fans. As expected, two 140mm fans come with the 280mm version we are reviewing today. These fans have rifle bearings, which are extremely quiet. They are a version of the “high speed” series, with a maximum speed of 1,600 rpm.
Be quiet! AIO refrigerator with clean loop 280 mm
The basic design of the Aure Pure Loop 280 mm cooler looks pretty typical at first glance. However, if you pay a little more attention, there is a significant anomaly: the liquid pump is autonomous and is not located on the main cooling block itself. The block only serves as a heat exchanger between the CPU and the coolant, without any moving parts.
Be quiet! moved the liquid pump up near the radiator, like a built-in device. While this probably serves the longevity of the pump well (since it is not directly exposed to very high temperatures) and reduces noise output by dampening its microvibrations, this approach also creates four more connection points. Usually, joints and other connection points are the weakest link in AIO cooler design, so additional points here increase the possibility of mechanical damage.
Be Quiet! They were a very subtle and elegant design for the main block. The body of the block is mostly made of plastic, supporting a copper contact plate. A decorative layer of brushed aluminum with the company logo covers the top of the assembly which has white LEDs that subtly illuminate its space as the unit is powered.
The bottom of the main block assembly reveals a large octagonal copper block that is nickel-plated. The finish is very smooth and flawless. The block is large enough for most modern desktop processors, excluding AMD’s oversized Ryzen Threadripper.
The radiator is a typical two-pass transverse flow design, with tiny fins soldered to thin oblong tubes. At the bottom of the radiator there is one relatively large screw that serves as a filling opening. Handling this requires caution – the position of the screw forbids users to undo it while the radiator is installed in the system, or the radiator will leak into the system itself. The radiator must be positioned so that the filler port is the highest point of the system, and then loosen the screw to add coolant. The series logo is printed on both sides of the radiator frame.
