be quiet! Pure Rock LP Low-Profile CPU Cooler

The Pure Rock LP delivers reliable cooling performance in an ultra-compact 45mm height design, making it the ideal CPU cooler for Mini-ITX builds and small form factor systems where space is at a premium. With 100W TDP cooling capacity and a maximum noise level of just 30.6dB(A), this cooler balances thermal performance with near-silent operation.

Ultra-Compact Design for Tight Builds

At just 45mm tall, the Pure Rock LP fits into virtually any PC case, including compact Mini-ITX builds and HTPCs where standard tower coolers won't fit. The 92 x 92 x 45mm dimensions make it the smallest cooler in the be quiet! lineup, while still providing sufficient cooling for mainstream processors up to 100W TDP.

Efficient Heat Dissipation

Three high-performance 6mm copper heat pipes transfer heat from the CNC-machined copper base to the aluminum fin array. The electrophoresis surface treatment ensures optimal heat transfer efficiency. This heat pipe configuration provides reliable cooling for HTPCs, multimedia systems, and compact gaming builds without thermal throttling.

Quiet 92mm PWM Fan

The included 92mm PWM fan features a high-quality rifle bearing rated for 80,000 hours of operation. At just 15mm thin, the fan spins up to 2500 RPM while maintaining quiet operation. PWM control allows the fan to adjust speed automatically based on CPU temperature, ranging from whisper-quiet 13.3dB(A) at 50% speed to 30.6dB(A) at full load.

Universal Socket Compatibility

The Pure Rock LP includes mounting hardware for both Intel and AMD platforms out of the box. Compatible sockets include Intel LGA 1851, 1700, 1200, 1150, 1151, and 1155, plus AMD AM5 and AM4. The user-friendly mounting system allows for straightforward installation even in cramped cases.
