1. To achieve better airflow rates and heat dissipation, we suggest that
you use a high quality fan with 3800 rpm at least. CPU fan and
heatsink installation procedures may vary with the type of CPU fan/
heatsink supplied. The form and size of fan/heatsink may also vary.
2. DO NOT remove the CPU cap from the socket before installing a
CPU.
3. Return Material Authorization (RMA) requests will be accepted
only if the motherboard comes with the cap on the LGA1156 socket.
