BeQuiet!’s most affordable liquid cooler with a 360-millimeter radiator. The price is already quite low, around one hundred euros, and a large radiator cooled by three fans is a good foundation for attractive results. And indeed, the results are just that. The cooling efficiency-to-price ratio here is truly impressive. The BeQuiet! Pure Loop 360 cooler is worth your attention.
The liquid BeQuiet! Pure Loop 3 coolers introduced at Computex 2025 are becoming a reality, meaning they are heading to retail. For this occasion, we analysed the variant with a 360-millimeter radiator in a test. Its codename is BW029US, and its price-to-cooling-performance ratio should be high within the AIO liquid cooler category. This is, after all, the Pure Loop series. So, for those who turned up their noses at the higher price of the Silent Loop 3, there is a new option.

Details of the BeQuiet! Pure Loop 3 (BW029US)
The radiator of the tested Pure Loop 3 cooler variant is in a 360 mm format. The material used for its construction is aluminum. The fins are then cooled by three Pure Wings 3 fans.
The fin density of the 27 mm thick radiator is “30”. This many fins are concentrated per square inch. They are situated between twelve liquid channels that run the entire length of the radiator.
The fans are 120-millimeter, with nine blades. These are the high-speed variants (we have separately tested the slower ones). At their maximum (100% PWM, or 12 V DC), they reach speeds of up to 2100 RPM. The blades of these fans feature the characteristic grooves on both sides, typical for BeQuiet!, and the high efficiency of this aerodynamic design is also notable. They will not disgrace the rest of the liquid loop, especially the radiator.
For a more elegant installation, the fan cables are interconnected, so you only connect a single connector to the motherboard. Elegant, clever, practical, and even at peak speeds, you should stay within 1 A, which is the current maximum often specified for traditional 4-pin headers on motherboards. At lower speeds, you will be well below this limit even with three Pure Wings 3 (high-speed) fans.
The pump speed for the liquid pump is stated as 5500 RPM. This is quite high, and based on this value, it is evident that a different pump is used inside the block compared to the Silent Loop 3 coolers. The coldplate, by the way, is copper, with a surface area of 55.5 × 55.5 mm. Contact with the CPU’s IHS will be one hundred percent, even on larger supported processors installed on Intel LGA 1851 or Intel LGA 1700 platforms. AMD Ryzen processors for AM5 or potentially AM4 motherboards are also supported.
On AMD platforms, you will use the backplate integrated into the motherboards for installation. The backplate for Intel is then supplied within the mounting accessories for Intel.
