This article covers be quiet! CPUクーラー 空冷 Pure Rock Pro 3 Intel 1851.

Overview

The be quiet! Pure Rock Pro 3 (model BK041) is a mid-range air CPU cooler from the German brand known for its silent operation. Despite its compact 154mm tower height, it handles CPUs with a TDP of up to 250W, covering a wide range of sockets including Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5/AM4. It comes with a single Pure Wings 3 120mm PWM fan that spins up to 2,000 rpm while keeping noise at a modest 34.8 dBA. The black-coated heatsink gives it a sleek, modern look that blends well with most PC builds.

Connectivity & Compatibility

The cooler supports Intel LGA1851 (Core Ultra 200 series), LGA1700 (12th-14th Gen Core), LGA1200, LGA1150/1151/1155, and AMD AM5 (Ryzen 7000/9000) and AM4 (Ryzen 3000-5000). This broad socket compatibility makes it suitable for both new builds and CPU upgrades on older platforms. The fan uses a standard 4-pin PWM header for automatic speed control. The asymmetrical heatsink design provides good clearance for tall memory modules, though extremely large VRM heatsinks on some motherboards may require careful orientation during installation.

Product Info

The Pure Rock Pro 3 sits in the upper-mid range of be quiet!'s air cooler lineup. It doesn't match the absolute silence of the Dark Rock series, but it offers an excellent balance of price, cooling capacity, and noise level for most builders. Released in early 2025, it is available as an officially imported product in Japan (BK041). The package includes Intel and AMD mounting kits, a backplate, a small tube of thermal compound, and an installation manual. The warranty is three years from the manufacturer.

Best Use Cases

Silent PC builders: The Pure Wings 3 fan stays quiet even under load at 34.8 dBA, making it ideal for quiet home offices or recording studios. Mid-range CPU users (Core i5/Ryzen 5-7): With a 250W TDP rating, it easily handles stock operation of these CPUs with headroom to spare. Compact case owners: At 154mm tall, it fits in most mid-tower cases where larger air coolers or liquid coolers won't. Budget-conscious builders: It offers strong value compared to high-end air coolers or AIOs, delivering reliable cooling without breaking the bank. If you plan to overclock a Core i9 or Ryzen 9 heavily, or demand absolute silence under any load, consider the larger Dark Rock Pro 5 or a liquid cooler instead.

Things to Consider

Always check your case's maximum CPU cooler height before purchasing. The Pure Rock Pro 3 is 154mm tall, and some cases may not close properly. Memory clearance is generally good, but if you use very tall RAM sticks in the slot closest to the CPU socket, verify clearance beforehand. The 250W TDP rating is a maximum specification; actual cooling performance depends heavily on case airflow and ambient temperature. For high-heat CPUs, ensure your case has adequate intake and exhaust fans. Intel LGA1851 is the socket for Core Ultra 200 series processors. Follow the included manual carefully to select the correct backplate and brackets for your specific socket.
