be quiet! Pure Rock Pro 3 Black Processor Air cooler 12 cm 1 pc(s)

The be quiet! Pure Rock Pro 3 Black is a compact, high-performance air cooler with a black covered heatsink and a 120 mm Pure Wings 3 fan. Its nickel-plated base transfers heat evenly to six heat pipes and the design supports compatibility with liquid metal thermal grease. With overall dimensions of 124 × 139 × 155 mm and a weight of 1.07 kg, the cooler fits most PC cases while providing cooling capacity suitable for CPUs with up to 250 W TDP.

Advantages

The cooler combines a dense, black-covered heatsink and an efficient 120 mm fan delivering up to 101.2 m³/h airflow at a maximum speed of 2000 RPM and up to 2.41 mmH2O air pressure. A nickel-plated base ensures even heat distribution across all six heat pipes, and the rifle-bearing fan improves durability. The compact size and universal mounting make it compatible with a wide range of sockets including AM5, AM4, LGA 1700 and several LGA 115x/1200 variants.

Suitable for

• Cooling mid-range to high-performance desktop CPUs (up to 250 W TDP)
• Builds requiring a compact air cooler with a premium black finish
• Systems where compatibility with liquid metal thermal grease is desired

How to use

Install the Pure Rock Pro 3 Black following the included mounting instructions for your specific socket. Apply thermal grease on the CPU surface; this cooler supports standard thermal pastes as well as liquid metal pastes—if using liquid metal, follow the liquid metal manufacturer's instructions and take care to avoid contact with surrounding components. Secure the cooler evenly to ensure optimal contact between the nickel-plated base and the CPU heat spreader, then connect the fan to the motherboard fan header for power and speed control.

Recommendations

For best performance, ensure adequate case airflow and periodically clean dust from the heatsink and fan. When using liquid metal, verify electrical insulation and retighten mounting hardware after a short thermal cycle if recommended by the thermal compound manufacturer.
