be quiet! Pure Loop 2 280 (280mm AIO Liquid/Noise-Optimized Design/PWM Fans/Quiet-Focused Mid-Tier) Review
The be quiet! Pure Loop 2 280 brings the brand's signature noise-first engineering philosophy to liquid cooling, occupying the 280mm radiator size tier that sits between the more common 240mm and 360mm options. It's built for buyers who want liquid cooling's thermal profile and clean aesthetic without the fan noise that can accompany higher-performance AIOs pushed toward maximum cooling capacity.

Thermal Performance and TDP Rating
A 280mm radiator splits the difference between the more compact 240mm and larger 360mm tiers, offering meaningfully more cooling surface area than a 240mm unit while fitting into cases that can't accommodate a full 360mm radiator. As with be quiet!'s air coolers, the engineering here prioritizes quiet operation over chasing the absolute highest thermal ceiling in this radiator size class.
Fan and Pump Design
Dual 140mm PWM fans, tuned specifically for be quiet!'s low-noise standards, deliver airflow through the radiator with the brand's characteristic acoustic restraint, the same philosophy that defines be quiet!'s air cooler lineup carried over into the liquid cooling space.
Socket Compatibility
Support for current AMD AM4/AM5 and Intel LGA1700/1851 covers mainstream current-generation builds.
Comparison to Sibling Products
Against the Arctic Liquid Freezer III 360, covered elsewhere on this site, that cooler offers more raw radiator surface area and Arctic's integrated VRM fan feature, while this be quiet! model's 280mm size fits a broader range of cases and specifically prioritizes low noise over maximum thermal headroom. Against the NZXT Kraken Elite 360, also covered elsewhere on this site, that cooler adds a large customizable LCD display this Pure Loop 2 doesn't include, at a real price and size premium.
Who This Cooler Is Actually For
Buyers who want liquid cooling's clean look with be quiet!'s established quiet-operation reputation. This is the direct extension of the brand's core identity into AIO cooling.
Cases that fit a 280mm radiator but not a full 360mm. This size tier serves a genuine middle ground many case layouts accommodate.
Not for buyers chasing the highest possible thermal ceiling in this radiator size class. The Arctic Liquid Freezer III lineup, covered elsewhere on this site, prioritizes raw performance more directly.
