Configuració i instal·lació
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.
- Compatibilitat de la placa base: Verify that your motherboard is based on the Intel 300 series chipset (e.g., Z370, B360, H310) and supports the LGA 1151 socket.
- Prepareu el sòcol: Open the CPU retention lever on the motherboard's LGA 1151 socket. Carefully lift the load plate.
- Instal·leu el processador: 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.
- Assegurar el processador: 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.

For best performance, ensure your operating system and drivers are up to date. Monitor CPU temperatures, especially during demanding tasks, to prevent thermal throttling.
Manteniment
Un manteniment adequat garanteix la longevitat i el rendiment estable del processador.
- Eliminació de pols: Regularly clean dust from the CPU heat sink and fan, as well as other internal PC components. Dust accumulation can impede airflow and lead to overheating. Use compressed air for effective cleaning.
- Pasta tèrmica: While the pre-applied thermal paste is durable, consider reapplying high-quality thermal paste every few years or if you notice increased temperatures. This requires carefully removing the heat sink, cleaning old paste, and applying new.
- Actualitzacions de controladors: Keep your motherboard chipset drivers and Intel graphics drivers updated. Visit the official Intel website or your motherboard manufacturer's weblloc per a les últimes versions.
- Actualitzacions de la BIOS/UEFI: Periodically check for BIOS/UEFI updates for your motherboard. These updates can improve compatibility, stability, and performance.
