## Long description

CPU air cooler with nickel-plated C1100 pure copper base, six 6 mm heatpipes and a stacked aluminum heatsink. The cooler includes a 120 mm PWM fan with fluid dynamic bearing, designed to fit a wide range of modern CPU sockets including LGA 1150/1151/1155/1156/1200/1700 and AMD AM4/AM5.
Advantages
The nickel-plated C1100 copper base improves heat transfer and corrosion resistance. Six 6 mm heatpipes provide efficient heat conduction from the CPU to the heatsink. The 120 mm PWM fan with fluid dynamic bearing balances airflow and low noise for continuous operation. Compatibility with multiple Intel and AMD sockets makes the cooler suitable for many mainstream desktop builds.

How to use
Mount the cooler following the motherboard and cooler manufacturer instructions: secure the mounting bracket to the motherboard socket compatible with your CPU, apply a thin, even layer of thermal paste on the CPU heatspreader, position the cooler so the heatpipes align with the bracket, and fasten the cooler with the supplied screws or clips. Connect the 4-pin PWM fan cable to the CPU fan header on the motherboard to enable automatic speed control. Verify clearance for RAM modules and case dimensions before final assembly.
Rekomendations
Use a compatible amount of thermal paste and ensure firm but not excessive mounting pressure. Confirm case airflow and fan orientation to achieve optimal cooling performance. For systems with tall memory modules or compact cases, check clearance measurements prior to installation.
