be quiet! Pure Rock 3 LX CPU Cooler - Compact High-Performance Cooling

The Pure Rock 3 LX delivers 190W TDP cooling capacity in a compact all-black design. Built for modern Intel and AMD processors, this air cooler combines efficient heat dissipation with quiet operation, reaching only 31.2dB(A) at maximum fan speed.

High-Performance Cooling Architecture

Four black 6mm copper heat pipes with HDT (Heat Pipe Direct Touch) technology transfer heat directly from the CPU to the aluminum fin array. The compact 71 x 124 x 154mm heatsink design ensures compatibility with high-profile RAM modules and VRM coolers while maintaining excellent thermal performance. The electrophoresis surface treatment provides durability and corrosion resistance.

Light Wings LX 120mm PWM Fan

The included Light Wings LX 120mm PWM fan operates at speeds up to 2000 RPM, delivering 61.85 CFM airflow and 2.51 mm H2O static pressure. The funnel-shaped air outlet optimizes airflow through the heatsink fins. The rifle bearing ensures 60,000 hours lifespan at 25°C. The 4-pole motor technology provides precise PWM control from 12.4dB(A) at minimum speed to 31.2dB(A) at full speed.

Universal Socket Compatibility

Compatible with Intel LGA 1851, 1700, 1200, 1150, 1151, and 1155 sockets, plus AMD AM5 and AM4 platforms. The preinstalled mounting bridge enables fast installation without complicated assembly. Offset mounting design optimizes contact with latest AMD Ryzen CPUs for improved thermal transfer.

Installation and Warranty

Pre-applied thermal compound eliminates additional preparation steps. The preinstalled cooler mounting bridge simplifies installation across both Intel and AMD platforms. Weighing just 0.57 kg, the Pure Rock 3 LX fits standard ATX cases with minimal clearance requirements. Backed by a 3-year manufacturer's warranty and certified with CE, UKCA, and UL approvals.
