Bravo be quiet! Pure Rock LP is designed for compact systems with limited space in the case. The main criteria were quiet operation and compatibility with a low-profile format, and this cooler handles that well. Installation went smoothly. The mounting is straightforward, and everything fits perfectly without any misalignment. The cooler itself looks neat; the black coating adds a restrained look and fits well into a build without bright elements. In operation, it performs reliably. The processor maintains comfortable temperatures for everyday tasks and light loads. The fan operates quietly, nearly inaudible against the background of the system, which was important for me. For a compact cooler, the result is more than satisfactory. Clearly, it's not an option for overclocking or high-end, hot processors, but within its intended purpose, it meets expectations fully. compact dimensions, suitable for small casesvery quiet operationneat appearanceeasy installation not suitable for powerful processors, cooling capacity is limited  Andriy Serdyuk: use be quiet!

be quiet! Pure Rock LP is a low profile CPU cooler that is jokingly called a pancake. Its height is 45 mm, which roughly corresponds to the boxed coolers Intel Laminar RM1 and AMD Wraith Stealth. At the same time, the creation of be quiet! much more efficient: instead of the typical 65 watts of heat, the entire 100 watts can be dissipated.
Copper pipes
Three copper heat pipes 6 mm in diameter pass through the aluminium fins. They contact the processor through the heat spreader plate. Pure Rock LP is installed on all current processor sockets: Intel LGA 1700, LGA 1200, AMD AM4 and AM5. While many other low-profile coolers are sharpened strictly for a specific socket.
