The be quiet! Pure Rock Pro 3 LX Black air cooler combines a compact form factor with high cooling performance. It pairs a black-covered heatsink with illuminated Light Wings LX fans and a nickel-plated base that distributes heat evenly across six heat pipes. The cooler supports liquid metal thermal grease and is designed for efficient heat dissipation in a sleek black finish.

Advantages

High cooling capacity for its size, support for liquid metal thermal grease, and an even heat distribution thanks to the nickel-plated base and six heat pipes. The included 120 mm Light Wings LX fan delivers up to 2000 RPM and an airflow of 105.1 m³/h while the rifle bearing improves durability. Compact dimensions make the cooler suitable for many builds without sacrificing performance.

Suitable for

• Cooling mid- to high-performance desktop CPUs (up to 250 W TDP)
• Systems requiring a compact cooler with good RAM and case compatibility

How to use

Install the Pure Rock Pro 3 LX Black following the motherboard and cooler mounting instructions: apply thermal paste (liquid metal is supported), position the cooler so the heat pipes contact the CPU, secure the mounting bracket, and connect the fan to the CPU_FAN or appropriate header. Ensure adequate case airflow and verify that the cooler fits your case and RAM clearance before final assembly.

Recommendations

For best results, use a compatible liquid metal thermal compound if you require the lowest possible CPU temperatures; otherwise use a high-quality standard thermal paste. Check clearances for tall RAM modules and confirm compatibility with your case layout and socket before purchase.
