MSI will deal with Return Merchandise Authorization (RMA) requests if only the motherboard comes with the protective cap on the CPU socket. ∙∙When installing a CPU, always remember to install a CPU heatsink. A CPU heatsink is necessary to prevent overheating and maintain system stability. ∙∙Confirm that the CPU heatsink has formed a tight seal with the CPU before booting your system. ∙∙Overheating can seriously damage the CPU and motherboard. Always make sure the cooling fans work properly to protect the CPU from overheating. Be sure to apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation. ∙∙Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with the plastic cap. ∙∙If you purchased a separate CPU and heatsink/ cooler, Please refer to the documentation in the heatsink/ cooler package for more details about installation. 13
