5. Setup and Installation
Before beginning installation, ensure your system is powered off and unplugged. Refer to your motherboard manual for specific CPU socket and mounting area details.
5.1 Prepare the CPU and Motherboard
- Carefully unbox your ID-COOLING IS-40X V3 cooler and verify all components are present.
- Ensure your CPU is correctly seated in its socket on the motherboard.
- Clean the surface of the CPU's integrated heat spreader (IHS) with isopropyl alcohol to remove any dust or old thermal paste.
- Apply a small amount of the provided thermal grease (FROST X25) to the center of the CPU's IHS. A pea-sized dot is usually sufficient. Do not spread it manually; the pressure from the cooler will spread it evenly.

5.2 Attach Mounting Brackets
Select the appropriate mounting brackets for your CPU socket type (LGA1700/1200 or AM4/AM5). The cooler supports both Intel and AMD platforms.
- For Intel LGA1700/1200 sockets, use the corresponding Intel mounting brackets.
- For AMD AM4/AM5 sockets, use the corresponding AMD mounting brackets.
- Secure the chosen brackets to the cooler's base using the provided screws. Ensure they are firmly attached.

5.3 Install the Cooler
- Carefully align the cooler with the mounting holes around the CPU socket.
- Gently place the cooler onto the CPU, ensuring the thermal paste spreads evenly.
- Secure the cooler to the motherboard using the appropriate screws, tightening them in a diagonal pattern to ensure even pressure. Do not overtighten.
- Connect the 3-pin fan power cable to the CPU_FAN header on your motherboard.

6. Operating Instructions
Once installed, the ID-COOLING IS-40X V3 operates automatically based on your motherboard's fan control settings. The 3-pin connector typically allows for voltage-based fan speed control (DC mode) or PWM control if supported by your motherboard and configured in the BIOS/UEFI.
- Fan Speed: The fan's speed will adjust between 800 and 2800 RPM depending on the CPU temperature, ensuring optimal cooling while minimizing noise.
- Noise Level: Designed for quiet operation, the maximum noise level is 35.2dB(A) under full load.
- Monitoring: You can monitor CPU temperatures and fan speeds using motherboard monitoring software or your system's BIOS/UEFI settings.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.
- Dust Removal: Periodically (every 3-6 months, or more often in dusty environments) use compressed air to blow dust out of the heatsink fins and fan blades. Hold the fan blades gently to prevent them from spinning too fast during cleaning, which can damage the bearing.
- Fan Cleaning: If dust accumulates on the fan blades and cannot be removed with compressed air, carefully remove the fan (if detachable) and clean the blades with a soft brush or cloth.
- Thermal Paste: The thermal paste typically lasts for several years. If you notice a significant increase in CPU temperatures, consider reapplying fresh thermal paste. This involves carefully removing the cooler, cleaning off old paste from both the CPU and cooler base, and applying new paste.
8. Troubleshooting
If you encounter issues with your CPU cooler, try the following troubleshooting steps:
- Fan Not Spinning:
- Check if the fan's 3-pin connector is securely plugged into the CPU_FAN header on the motherboard.
- Verify fan settings in your motherboard's BIOS/UEFI. Ensure fan control is enabled and not set to a very low RPM or 'off' at low temperatures.
- Inspect the fan for any obstructions preventing it from spinning.
- High CPU Temperatures:
- Ensure the cooler is properly seated and making good contact with the CPU. Uneven pressure can lead to poor thermal transfer.
- Check if enough thermal paste was applied, or if it needs to be reapplied.
- Clean any dust accumulation from the heatsink fins and fan blades.
- Verify that the fan is spinning at appropriate speeds.
- Ensure adequate airflow within your PC case.
- Excessive Noise:
- Check for any cables or objects interfering with the fan blades.
- Adjust fan speed settings in your motherboard's BIOS/UEFI to a lower RPM if temperatures allow.
- Clean the fan blades and bearing area for any debris.
9. User Tips
- This low-profile cooler is particularly well-suited for compact PC cases where standard tower coolers would not fit. Always check your case's CPU cooler clearance before purchase.
- When installing, ensure the mounting pressure is even across the CPU to maximize thermal contact.
- For optimal performance, ensure good case airflow by having intake and exhaust fans properly configured.
10. Warranty and Support
The ID-COOLING IS-40X V3 CPU Air Cooler comes with a 3-year warranty, as indicated in the product specifications. For warranty claims, technical support, or any product-related inquiries, please contact the manufacturer or your point of purchase. Keep your proof of purchase for warranty validation.
