4. Setup and Installation
Proper installation is crucial for optimal performance. Please follow these general steps. Refer to your motherboard's manual for specific socket instructions.
- Prepare the Motherboard: Ensure your motherboard is removed from the PC case or has sufficient access for cooler installation.
- Install Backplate (if required): For Intel sockets, attach the appropriate backplate to the rear of the motherboard, aligning it with the CPU cooler mounting holes. AMD AM4/AM5 typically use the stock backplate.
- Attach Mounting Brackets: Secure the correct mounting brackets to the heatsink base using the provided screws. Ensure they are firmly attached.
- Apply Thermal Paste: Clean the CPU surface thoroughly. Apply a small amount of thermal paste (included) to the center of the CPU's integrated heat spreader (IHS). A pea-sized dot is usually sufficient.
- Mount the Cooler: Carefully place the heatsink assembly onto the CPU, aligning the mounting screws with the holes on the backplate or motherboard retention module. Tighten the screws in a diagonal pattern (e.g., top-left, bottom-right, top-right, bottom-left) until snug, ensuring even pressure. Do not overtighten.
- Connect Fan Cable: Connect the 4-pin PWM fan cable to the CPU_FAN header on your motherboard.
- Verify Installation: Double-check that the cooler is securely mounted and the fan cable is properly connected. Ensure there is no interference with RAM modules or other components.

5. Operating Instructions
The ID-COOLING IS-55 CPU Cooler operates automatically once installed and powered on. The 120mm PWM fan adjusts its speed based on the CPU temperature, as controlled by your motherboard's BIOS/UEFI settings or operating system software.
- Automatic Speed Control: The fan's PWM (Pulse Width Modulation) function allows the motherboard to precisely control its rotational speed (RPM) in response to the CPU's thermal load. This ensures efficient cooling when needed and quiet operation during lighter tasks.
- BIOS/UEFI Settings: For advanced users, fan curves can be customized within your motherboard's BIOS/UEFI settings to prioritize noise levels or cooling performance according to your preference.
- Monitoring: You can monitor CPU temperatures and fan speeds using various software utilities available for your operating system.
6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.
- Dust Cleaning: Periodically inspect the heatsink fins and fan blades for dust accumulation. Use compressed air or a soft brush to gently remove dust. Ensure the fan is held stationary while cleaning with compressed air to prevent over-spinning and potential damage.
- Thermal Paste Reapplication: Over time, thermal paste can dry out, reducing its effectiveness. It is recommended to reapply thermal paste every 2-3 years, or if you remove the cooler for any reason. Clean both the CPU IHS and the cooler's base thoroughly before applying new thermal paste.
- Fan Inspection: Check the fan for any unusual noises or wobbling. If the fan becomes excessively noisy or stops spinning, it may need to be replaced.
7. Troubleshooting
If you encounter issues with your CPU cooler, consider the following common troubleshooting steps:
- High CPU Temperatures:
- Ensure the cooler is securely mounted and making good contact with the CPU. Uneven pressure can lead to poor heat transfer.
- Verify that thermal paste was applied correctly and is not dried out. Reapply if necessary.
- Check for proper airflow within your PC case. Ensure case fans are configured to provide adequate intake and exhaust.
- Confirm the CPU fan is spinning.
- Fan Not Spinning or Spinning Slowly:
- Check if the fan cable is securely connected to the CPU_FAN header on the motherboard.
- Enter your motherboard's BIOS/UEFI and check fan speed settings. Ensure PWM control is enabled and the fan curve is appropriate.
- Test the fan by connecting it to a different fan header (if available) or a fan controller to rule out a faulty fan.
- Excessive Noise:
- Check for dust buildup on the fan blades or heatsink fins. Clean thoroughly.
- Ensure no cables are obstructing the fan blades.
- If the noise is a grinding or rattling sound, the fan bearing may be failing. Consider replacing the fan.
- Adjust fan speed settings in BIOS/UEFI to a quieter profile if temperatures allow.
