Орнотуу жана орнотуу
Installing your Intel Core i5-8400 processor requires careful handling and adherence to proper procedures. Ensure your system is powered off and unplugged before beginning installation.
- Motherboard шайкештиги: Verify that your motherboard is based on the Intel 300 series chipset (e.g., Z370, B360, H310) and supports the LGA 1151 socket.
- Сокетти даярдаңыз: Open the CPU retention lever on the motherboard's LGA 1151 socket. Carefully lift the load plate.
- Процессорду орнотуу: Gently align the processor with the socket, ensuring the gold triangle on the processor matches the triangle on the socket. Lower the processor straight down into the socket without forcing it.
- Процессорду коргоо: Close the load plate and push down the retention lever until it clicks into place.
- Install the Heat Sink and Fan: The included Intel stock heat sink has pre-applied thermal paste. Align the four push-pins on the heat sink with the holes around the CPU socket on the motherboard. Press down firmly on each pin until it clicks, ensuring it is securely fastened. Connect the heat sink fan cable to the CPU_FAN header on your motherboard.
