3.2 Installation Steps (General)

1. Prepare CPU and Motherboard: Ensure your CPU is correctly seated in its socket. Clean the CPU surface of any old thermal paste using isopropyl alcohol.
2. Apply Thermal Paste: Apply a small amount of thermal paste (included) to the center of the CPU's Integrated Heat Spreader (IHS).
3. Attach Mounting Brackets: Select the appropriate mounting brackets for your CPU socket (Intel LGA1700/1200/115X or AMD AM5/AM4). Secure them to the motherboard according to the diagrams provided in the cooler's specific installation guide.
4. Position the Cooler: Carefully place the heatsink assembly onto the CPU, aligning the mounting holes. The cooler can be oriented to avoid interference with RAM modules or I/O ports.
5. Secure the Cooler: Use the provided screws to secure the cooler to the mounting brackets. Tighten screws gradually in a cross pattern to ensure even pressure.
6. Connect Fan Cable: Connect the 4-pin PWM fan cable to the CPU_FAN header on your motherboard.

3.3 Recommended Installation Orientation

For optimal compatibility and clearance, it is recommended to orient the cooler so that the bends of the heatpipes face the RAM modules. This configuration helps avoid interference with memory, I/O, and GPU components.

4. Operating Instructions

Once installed, the ID-COOLING IS-77-XT operates automatically. The 120mm PWM fan adjusts its speed based on the CPU temperature, as controlled by your motherboard's BIOS settings. Ensure proper airflow within your PC case for optimal cooling performance.

4.1 Airflow Direction

The fan is pre-installed underneath the fin stack, blowing downwards. This orientation draws cool external air directly through the heatsink, contributing to efficient CPU temperature reduction. This setup also helps reduce turbulence noise when drawing air through the side panel of a case.

5. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.

• Dust Cleaning: Periodically clean dust from the heatsink fins and fan blades using compressed air or a soft brush. Ensure the fan is not spinning during cleaning.
• Fan Inspection: Check the fan for any obstructions or signs of wear. Ensure the fan cable is securely connected.
• Thermal Paste: If CPU temperatures increase significantly over time, consider reapplying thermal paste. This typically involves removing the cooler, cleaning old paste from both the CPU and cooler base, and applying new thermal paste.
