If this is not the case, then purchase a correct cooling FAN before you turn onyour system.WARNING! Be sure that there is sufficient air circulation across the processor’sheatsink and CPU cooling FAN is working correctly, otherwise it maycause the processor and motherboard overheat and damage, you may installan auxiliary cooling FAN, if necessary.To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket andopen it by first pulling the level sideways away from the socket then upward to a 90-degreeangle. Insert the CPU with the correct orientation as shown below. The notched cornershould point toward the end of the level. Because the CPU has a corner pin for two of thefour corners, the CPU will only fit in the orientation as shown.CPU ZIF mPGAB SocketColden ArrowSocket 939When you put the CPU into the ZIF socket.
