The be quiet! Pure Rock CPU Cooler is a high-performance cooling solution designed to maintain optimal operating temperatures for your computer's central processing unit. It is engineered for quiet operation and efficient heat dissipation, ensuring stable system performance even under heavy loads. The cooler is compatible with a wide range of Intel and AMD sockets, making it a versatile choice for various PC builds.
The primary function of the Pure Rock CPU Cooler is to draw heat away from the CPU and dissipate it into the surrounding air, preventing overheating and potential damage to the processor. This is achieved through a combination of a heatsink, heat pipes, and a fan. The heatsink, typically made of aluminum fins, provides a large surface area for heat exchange. Integrated heat pipes, usually made of copper, efficiently transfer heat from the CPU's integrated heat spreader (IHS) to the heatsink fins. A 120mm fan then moves air across these fins, accelerating the cooling process.
The cooler utilizes a direct contact heat pipe design, where the heat pipes directly touch the CPU's surface, maximizing heat transfer efficiency. The included 120mm fan is designed for quiet operation, often featuring a rifle bearing or similar technology to reduce noise and increase lifespan. It connects to the motherboard's PWM (Pulse Width Modulation) signal, allowing for dynamic fan speed control based on CPU temperature, which further contributes to both cooling performance and acoustic optimization.
The Pure Rock CPU Cooler is designed for straightforward installation, though preparatory mounting outside the PC case is recommended for ease of assembly. The manual provides detailed, step-by-step instructions for installation on various Intel and AMD platforms, including LGA 2011(-3) square ILM/LGA 2066, LGA 1150/1151/1155/1156/1366, and AMD AM2(+)/AM3(+)/AM4/FM1/FM2(+).
For Intel LGA 2011(-3) square ILM/LGA 2066 sockets, the installation involves screwing Intel spacer nuts onto the socket frame threads, placing Intel mounting brackets over these nuts, and securing them with mounting bracket fastening screws. The cooler mounting bridge is then positioned centrally on the cooler, and the entire unit is placed onto the CPU. Intel/AMD mounting bridge fastening screws are inserted from above into the cooler mounting bridge and alternately tightened.
For Intel LGA 1150/1151/1155/1156/1366 sockets, the process begins with positioning Intel backplate screws in the notches of the Intel backplate, ensuring alignment with motherboard holes. O-rings are used to fix the backplate screws. The assembled backplate is then positioned under the motherboard. Intel 115X/1366 nuts are screwed onto the backplate bolts, followed by positioning Intel mounting brackets over these nuts and securing them with mounting bracket fastening screws. The cooler mounting bridge is then placed on the cooler, and the unit is mounted onto the CPU, securing it with Intel/AMD mounting bridge fastening screws.
For AMD AM2(+)/AM3(+)/AM4/FM1/FM2(+) sockets, the existing plastic retainers of the AMD retention module must be removed, as the factory-fitted backplate is utilized. For AM3 motherboards, AM3 washers are placed below the backplate bolts. AMD spacer nuts are placed onto the backplate bolts, and long AMD mounting brackets are affixed with AMD backplate screws. The cooler mounting bridge is then positioned on the cooler, and the unit is placed onto the CPU, secured with Intel/AMD mounting bridge fastening screws.
In all installations, the 120mm fan is fastened to the cooler unit using fan clips and connected to the motherboard's PWM signal. A crucial step before mounting the cooler is to remove the protective covering from the underneath of the cooler, which exposes the pre-applied thermal paste or the bare contact surface.
The be quiet! Pure Rock CPU Cooler is designed for minimal maintenance, primarily focusing on the fan. The 120mm fan can be easily detached from the heatsink for cleaning or replacement. To dismantle the fan, the notches of the fan clips are pushed away from the fan, allowing it to be removed. This feature facilitates periodic cleaning of dust accumulation on the fan blades and heatsink fins, which is essential for maintaining optimal cooling performance. Dust buildup can impede airflow and reduce the cooler's efficiency, so regular cleaning is recommended.
The thermal paste, which is crucial for efficient heat transfer between the CPU and the cooler, is pre-applied to the cooler's base. While the manual does not explicitly detail reapplication, it is a standard maintenance practice for CPU coolers to reapply thermal paste when the cooler is removed and reinstalled, or after a long period of use, to ensure continued optimal performance. The manual includes a caution regarding the thermal paste, stating it is not suitable for human consumption and advising immediate medical attention if swallowed, along with keeping it out of reach of children and avoiding skin and eye contact.
The cooler is backed by a 3-year manufacturer guarantee for consumers, provided the original purchase was made from authorized be quiet! dealers. Guarantee work requires a copy of the purchase receipt. The warranty is voided by manipulation, structural changes, or any damage caused by external mechanical force. This highlights the importance of careful handling and proper installation to ensure the longevity and warranty coverage of the device. The design, with its robust heatsink and easily detachable fan, allows for straightforward cleaning and inspection, contributing to its overall maintainability.
