- The Be Quiet! Pure Rock 3 LX (BK040) is a high-performance CPU air cooler designed to provide reliable and efficient cooling for modern gaming PCs, desktop computers, and performance-focused systems. With a 190W TDP cooling capacity, this tower-style CPU cooler helps manage processor temperatures during gaming, multitasking, content creation, and other demanding workloads.

The 4-pin PWM connection allows compatible motherboards to automatically adjust fan speed according to CPU temperature and system load.

- With its compact tower design, black finish, ARGB illumination, PWM fan control, and efficient heat dissipation, the Pure Rock 3 LX is a practical choice for users building or upgrading a gaming or high-performance desktop PC. Its combination of cooling capability, modern aesthetics, and broad socket compatibility makes the BK040 CPU cooler suitable for a variety of PC configurations.
