This article covers be quiet! CPUクーラー PURE LOOP 3 360mm オールインワン ブラック Intel 1851.
Overview
The be quiet! PURE LOOP 3 360mm is an all-in-one liquid CPU cooler compatible with Intel LGA1851/1700/1200/115x and AMD AM4/AM5 sockets. With a 360mm radiator measuring 397×120×52mm, it delivers excellent cooling capacity while maintaining impressively low noise levels. Equipped with a PWM-controlled pump and three PURE WINGS 3 PWM fans, this cooler achieves a maximum noise output of just 37.2 dBA at 2,100 RPM fan speed. It strikes a strong balance between thermal performance and acoustic comfort, making it a versatile choice for both high-end gaming PCs and quiet workstations.
Connectivity & Compatibility
The PURE LOOP 3 supports Intel LGA1851/1700/1200/1150/1151/1155 and AMD AM4/AM5 sockets, covering virtually all modern mainstream platforms. Full compatibility with Intel's LGA1851 (Arrow Lake) means future CPU upgrades won't require a new cooler. Both fans and pump connect via standard 4-pin PWM headers. The pump can be connected to the motherboard's AIO pump header for dedicated speed control. The 360mm radiator fits in most mid-tower and full-tower cases designed for triple-fan radiators — just ensure case clearance of at least 52mm depth is available.
Product Info
The PURE LOOP 3 sits in be quiet!'s mid-range liquid cooling lineup. Priced around ¥14,000–¥16,000 (approx. $95–$110 USD), it offers competitive value for a 360mm AIO. The official Japanese model (BW029EU) includes a 3-year manufacturer warranty. In the box you get mounting kits for Intel and AMD, a backplate, thermal paste, and an installation guide. The all-black radiator and sleeved tubing help maintain a clean aesthetic inside the case.
Best Use Cases
Silence-focused builders: With noise capped at 37.2 dBA under full load, this cooler excels in environments where acoustic comfort is critical — for example, late-night gaming or audio production. High-TDP CPU users: The 360mm radiator is more than sufficient for Ryzen 9 or Core i9 processors, even under sustained all-core loads. It also handles moderate overclocking without ramping up fan noise. * Future-proof PC planners: LGA1851 compatibility means you can keep this cooler when upgrading to Intel's next-generation platform, reducing long-term cost.
