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.
Usage 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.
