be quiet! Pure Loop

be quiet! startet mit dem Pure Loop einen zweiten und komplett neuen Anlauf in die Welt der AiO-Wasserkühlungen. Der Pure Loop bietet ein stimmiges Gesamtpaket. Eine verhältnismäßig leise Pumpe erzielt zusammen mit den bekannten Pure-Wings-Lüftern ein ordentliches Kühlvermögen zu einem günstigen Preis.

Mit der neuen Pure Loop-Serie will be quiet! AiO-Kühlungen für preisbewusste Käufer anbieten. Versprochen werden leise und leistungsstarke Modelle - und als Besonderheit die Möglichkeit, die Kühlflüssigkeit nachzufüllen. Eine Flasche mit Kühlflüssigkeit gehört sogar gleich zum Lieferumfang. Im Test finden wir heraus, wie sich das größte Modell mit 360-mm-Radiator im Vergleich zur Konkurrenz schlägt.

The newest and arguably most hirsute member of the bit-tech review team, Andy Makin, puts his cooling expertise to good use by taking an in-depth look at the be quiet! Pure Loop 360 all-in-one cooler. Are beards necessary to feature on bit-tech? No, but they certainly help!

If you are after top-performance better look elsewhere (for example Corsair Capelix 150i or 115i) but beware, you will pay more. Now, if you want silent operation and good performance along with a top performance per buck ratio, you should check the Pure Look 360mm. In this price range, its performance is very good and the same goes for the performance per noise (dBA) ratio.

In conclusion, we find that the Be Quiet! Pure Loop 280 cooler is an excellent product. Even with the focus on keeping noise levels down, Be Quiet! hasn't left thermal performance behind, so the Pure Loop offers a very good balance between thermal performance and acoustics. And they're able to do all of this while keeping the price of the cooler quite reasonable (despite the ongoing pandemic), with the Pure Loop 280 easily found for less than $110. Taking in consideration both the cooler's performance and that low price tag, we can say that the Pure Loop 280 is a very good deal for users who want great overall cooler performance combined with an elegant appearance.

We tell it like it is; we always have and will do that. And I am afraid that we'll not be recommending the Pure Loop series at this time. It's certainly not bad in performance or acoustics; contrary, it's actually quite good for the money. But the paradox is that within that low 35 DBa acoustic spectrum, the pump hardly is bearable to hear as it's there anytime and all the time, that buzzing noise and resonation it makes lifts it to a rather bothersome level.

The be quiet! Pure Loop 280 will not set the world on fire in terms of performance; however, it still does quite well. It typically traded blows with the Deepcool Castle 280EX, Corsair H115i Platinum, and Fractal Design Celsius+ S28 Prisma, while being a tiny bit quieter at maximum RPM. It should be noted that the pump is mounted on the tubing, meaning there was little to no pump noise with this model. Instead, the noise users will hear is entirely related to the fan's airflow. This did give it a more pleasing noise profile, at least subjectively.

With so many all-in-one liquid coolers placing a greater emphasis on RGB lighting and software customisation, it's refreshing to examine an alternative focussed squarely on hardware optimisations. be quiet!'s Pure Loop eschews the glitzy extras and instead introduces a handful of intriguing hardware tweaks with varying levels of success. The pump, moved from above the processor to a decoupled unit further up the tubes, hasn't proved noticeably quieter in our testing but does result in a low-profile CPU block that's particularly sleek.

Die be quiet Pure Loop ist zwar keine Silent-Wasserkühlung, schafft den Spagat zwischen Leistung und Lautstärke aber durchaus gut. Besonders angenehm ist die Wasserkühlung im Leerlauf, da agiert sie ausgesprochen leise.

Mit der Pure Loop Serie folgt von be quiet! ein neuer Anlauf im AIO-Markt ein neuer Anlauf, der vor allem preisbewusste User ansprechen soll, die zwar auf "Schnick-Schnack" aber nicht auf Kühlleistung und eine dezente Optik bei einer AIO verzichten wollen. Die neue Kühlung wird es in den Radiatorgrößen von 120, 240, 280 und 360-mm angeboten. Das Ganze in einem Preisbereich von 85 bis ca. 120 Euro. Wir schauen uns die 240-Version genauer an.

Mit der Pure Loop-Serie möchte be quiet preisbewusste Anwender ansprechen, die aber nicht auf Kühlleistung verzichten möchten. Dieses Ziel erreicht be quiet! mit der Pure Loop 240 in unserem Test auch. Für einen Preis von ca. 95 Euro bekommt man neben einer guten Kühlleistung auch eine schöne und dezente Optik, eben typisch be quiet!.

Pure Loop 240mm is built from high-quality materials, is easy to install thanks to the provided instructions and provides an innovative pump design for eliminating noise and vibrations inside the case. While this version of the Pure Loop is indicated as recommended for i3/i5 processors from Intel, it could handle the power-hungry i7-12700K CPU as well, by keeping the temperatures under TjMAX, while the noise levels remained at low levels due to the use of two Pure Wings 2 120mm fans.

Right at the beginning of this review, we suggested that although not releasing with a particularly large amount of fanfare, be quiet! was seemingly somewhat pleased with what they had achieved here with the Pure Loop design. Now that we’ve had a look at the cooler components and test results, although I always suspected that the Pure Loop 240mm was always going to be very good, even I’ll admit that this was massively better than even my wildest expectations.

I came in excited to see what a company like be quiet! could do when finally getting into the all in one market and they didn’t disappoint. They avoided going with just the standard OEM setup with their branding on it. Especially on the pump side where they changed things up completely. The radiator is mostly like an OEM design with its aluminum design and it has the same fin spacing and thickness as any other AIO. Where it does stand out however is be quiet! supporting topping the coolant off in the loop with an easy to use fill port and them including coolant with everything. They suggest topping things off every two years and any other time it is needed and this should help a lot with the overall life of the system. Especially when paired with be quiet! fans which have an 80,000 hour expected life.
