FEATURES
- 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.

- The be quiet! Pure Rock 3 LX BK040 is compatible with a wide range of Intel and AMD processors. Supported Intel sockets include LGA 1851, LGA 1700, LGA 1200, LGA 1150, LGA 1151, and LGA 1155, while AMD compatibility includes AM4 and AM5 sockets.
- 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.
