5. Installation Guide
Follow these steps carefully to install your upHere D6SEC CPU Air Cooler. The design allows for installation without removing the fans, simplifying the process.
5.1. Prepare the CPU and Motherboard
- Ensure your motherboard is removed from the PC case for easier access.
- Clean the CPU surface thoroughly to remove any old thermal paste or debris.
5.2. Install Mounting Hardware (Intel)
- Adjust the Intel backplate according to your CPU socket (115X/1200, 1700, or 1366).
- Place the backplate on the rear side of the motherboard, aligning the holes with the CPU socket.
- From the front side of the motherboard, insert the standoffs through the mounting holes.
- Secure the mounting brackets onto the standoffs using the provided screws. Ensure they are tightened evenly.

5.3. Install Mounting Hardware (AMD)
- Remove the existing plastic retention modules from the motherboard, keeping the original backplate.
- Install the AMD standoffs into the motherboard's mounting holes.
- Secure the AMD mounting brackets onto the standoffs using the provided screws. Ensure they are tightened evenly.
5.4. Apply Thermal Paste
- Apply a small, pea-sized amount of thermal paste to the center of the CPU's integrated heat spreader (IHS).
- Use the provided spatula to spread the thermal paste evenly across the entire surface of the CPU IHS in a thin layer.
5.5. Mount the CPU Cooler
- Remove the protective film from the cooler's base.
- Carefully place the CPU cooler onto the CPU, aligning the mounting screws on the cooler with the holes on the installed mounting brackets.
- Using a screwdriver, tighten the screws in an alternating diagonal pattern (e.g., top-left, bottom-right, top-right, bottom-left) until snug. Do not overtighten.
5.6. Connect Fan and ARGB Cables
- Connect the 4-pin PWM fan cable from the cooler 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 correct polarity to avoid damage.

6. Operating Instructions
Once installed, the upHere D6SEC CPU Air Cooler operates automatically based on your motherboard's fan control settings.
- PWM Fan Control: The dual 120mm PWM fans adjust their speed (600-1600 RPM) according to CPU temperature, providing optimal cooling performance while minimizing noise.
- ARGB Lighting: The 5V ARGB lighting can be synchronized with compatible motherboards using their respective software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion). This allows for customization of lighting effects and colors.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your CPU cooler.
- Dust Cleaning: Periodically clean the heatsink fins and fan blades to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Thermal Paste Replacement: It is recommended to replace the thermal paste every 2-3 years, or if you remove the cooler for any reason, to maintain optimal heat transfer.
- Fan Inspection: Check fan cables for secure connections and ensure fans spin freely without obstruction or unusual noise.
8. Troubleshooting
If you encounter issues with your CPU cooler, refer to the following common troubleshooting steps.
- High CPU Temperatures:
- Ensure the cooler is securely mounted and making full contact with the CPU.
- Verify that thermal paste was applied correctly and evenly.
- Check if fan cables are properly connected to the CPU_FAN header.
- Clean any dust buildup from the heatsink and fans.
- Confirm fan speed settings in your motherboard's BIOS/UEFI are appropriate.
- Fans Not Spinning/ARGB Not Lighting Up:
- Check all fan and ARGB cable connections to the motherboard.
- Ensure the 5V ARGB header is enabled in your motherboard's BIOS/UEFI and controlled by compatible software.
- Verify that the power supply is providing sufficient power.
- Unusual Fan Noise:
- Inspect fans for any obstructions (cables, debris).
- Ensure fans are securely attached to the heatsink.
- If noise persists, consider adjusting fan curves in BIOS/UEFI to lower RPMs at idle.
