5. Diegimo vadovas
Before starting, ensure your system is powered off and unplugged. Refer to your motherboard manual for specific CPU socket information.
5.1 Paruoškite pagrindinę plokštę
- Install the appropriate backplate for your CPU socket (Intel or AMD) onto the rear of the motherboard.
- Secure the standoffs through the motherboard's mounting holes into the backplate.
5.2 Apply Thermal Paste
- Clean the CPU surface and the cooler's base with isopropyl alcohol.
- Apply a small, pea-sized amount of thermal paste to the center of your CPU's IHS (Integrated Heat Spreader). Do not spread it manually; the pressure from the cooler will distribute it evenly.
5.3 Mount the Cooler
- Attach the correct mounting brackets (Intel or AMD) to the base of the M400 cooler.
- Carefully place the M400 cooler onto the CPU, aligning the mounting holes on the brackets with the standoffs on the motherboard.
- Secure the cooler by tightening the screws in a diagonal pattern until snug. Do not overtighten.

5.4 Prijunkite kabelius
- Connect the 4-pin PWM fan cable to the CPU_FAN header on your motherboard.
- Connect the 5V 3-pin ARGB cable to a compatible 5V ARGB header on your motherboard. Ensure it is a 5V header and not a 12V RGB header to prevent damage.
The M400's tilted design allows for convenient installation without needing to remove the fan, ensuring compatibility with most memory modules.
6. Operacija
6.1 skaitmeninis temperatūros ekranas
Once your system is powered on, the segmented screen on the top cover of the M400 will automatically display the real-time CPU temperature in Celsius. This provides an immediate visual reference for your CPU's thermal status.

6.2 ARGB apšvietimo valdymas
The 120mm fan features Addressable RGB (ARGB) lighting. If connected to a compatible 5V 3-pin ARGB header on your motherboard, you can control the lighting effects using your motherboard's synchronization software, such as:
- ASUS AURA SYNC
- GIGABYTE RGB FUSION 2.0
- MSI MYSTIC LIGHT SYNC
- ASROCK POLYCHROME RGB
Refer to your motherboard's manual for instructions on using its ARGB control software.
6.3 Ventiliatoriaus greičio valdymas (PWM)
The 4-pin PWM fan connector allows your motherboard to automatically adjust the fan speed (800-2000 RPM) based on the CPU temperature. This ensures optimal cooling performance when needed and quieter operation during lighter loads. You can typically configure fan curves in your motherboard's BIOS/UEFI settings or through dedicated software.
7. Priežiūra
Regular maintenance helps ensure optimal performance and longevity of your CPU cooler.
- Dulkių valymas: Periodically (e.g., every 3-6 months), power off your system and use compressed air to remove dust buildup from the heatsink fins and fan blades. Ensure the fan does not spin freely during cleaning to prevent damage to the bearing.
- Terminė pasta: Over time, thermal paste can dry out and lose effectiveness. Consider reapplying thermal paste every 1-2 years, or if you notice a significant increase in CPU temperatures.
- Kabelių valdymas: Ensure all cables are neatly routed and not obstructing airflow within your PC case.
8. Problemų sprendimas
8.1 Fan Not Spinning / ARGB Not Lighting Up
- Patikrinkite jungtis: Ensure the 4-pin PWM fan cable is securely connected to the CPU_FAN header and the 5V 3-pin ARGB cable is connected to the correct 5V ARGB header on your motherboard.
- BIOS nustatymai: Verify that the CPU_FAN header is enabled in your motherboard's BIOS/UEFI settings.
- Programinės įrangos konfliktas: If using ARGB software, try restarting it or reinstalling motherboard drivers.
8.2 High CPU Temperatures
- Terminė pasta: Ensure thermal paste was applied correctly and is not dried out. Reapply if necessary.
- Mounting Pressure: Check that the cooler is securely mounted and making good contact with the CPU. Ensure screws are tightened evenly.
- Oro srautas: Verify that your PC case has adequate airflow and that the cooler's fan is oriented correctly to push air through the heatsink.
- Dulkių susidarymas: Clean any dust from the heatsink fins and fan blades.
8.3 Neveikiantis skaitmeninis ekranas
- Patikrinkite jungtis: Ensure all cables are properly connected. The digital display typically draws power from the same fan or ARGB connection.
- Pagrindinės plokštės suderinamumas: While the display is generally independent, ensure your motherboard's sensor readings are functioning correctly.
9. Vartotojo patarimai
- Terminė pasta: Always ensure you have thermal paste available for installation. If your package did not include it (common for international shipments), purchase a high-quality thermal compound separately.
- Kabelių valdymas: Take time to route the fan and ARGB cables neatly. This not only improves aesthetics but also prevents cables from interfering with airflow or other components.
- BIOS / UEFI nustatymai: After installation, check your motherboard's BIOS/UEFI settings to ensure the CPU fan is detected and operating in PWM mode for optimal performance and noise control.
