4. Setup and Installation
Follow these steps for proper installation of your ALSEYE W90 CPU Cooler:
- Prepare Motherboard: Ensure your motherboard is compatible with Intel LGA 1700, 1200, or 115X sockets. Clean the CPU surface of any old thermal paste.
- Install Backplate: Place the appropriate Intel backplate on the rear of the motherboard, aligning the holes.
- Attach Mounting Screws: Insert the mounting screws through the motherboard from the front, securing them to the backplate.
- Apply Thermal Paste: If not pre-applied, apply a small, pea-sized amount of thermal paste to the center of the CPU's integrated heat spreader (IHS).
- Position Cooler: Carefully place the ALSEYE W90 CPU Cooler onto the CPU, ensuring the mounting holes on the cooler align with the screws.
- Secure Cooler: Tighten the mounting screws in a diagonal pattern until the cooler is firmly seated. Do not overtighten.
- Connect Cables: Connect the 4-pin PWM fan cable to the CPU_FAN header, the 3-pin ARGB cable to a compatible 5V ARGB header, and the temperature display cable to a USB 2.0 header on your motherboard.
- Verify Orientation: Ensure the temperature display is oriented correctly for optimal viewing within your PC case.

5. Operating Instructions
Temperature Display
The integrated display on the cooler shows the real-time CPU temperature. For precise temperature readings and control, install the ALSEYE "BEM" software, which reads the CPU temperature directly.

ARGB Lighting Control
The ARGB lighting can be controlled via your motherboard's ARGB software (if connected to a 5V ARGB header) or through the ALSEYE "BEM" software. This allows for various lighting effects and synchronization with other ARGB components.

Fan Speed Control (PWM)
The fan speed is automatically controlled by the motherboard's PWM function based on CPU temperature. You can adjust fan curves through your motherboard's BIOS/UEFI settings or dedicated software to optimize for performance or quiet operation.

6. Maintenance
- Dust Removal: Periodically clean the fan blades and heatsink fins with compressed air or a soft brush to prevent dust buildup, which can impede cooling performance. Ensure the system is powered off before cleaning.
- Thermal Paste: Reapply thermal paste every 1-2 years or if the cooler is removed and reinstalled.
- Cable Management: Ensure all cables are neatly routed and do not obstruct airflow.
7. Troubleshooting
- High CPU Temperatures:
- Verify proper installation and contact between the cooler base and CPU.
- Check if thermal paste was applied correctly.
- Ensure fan is spinning and not obstructed.
- Confirm fan speed settings in BIOS/software.
- Note: This cooler has a TDP of approximately 135W and is not recommended for overclocking or high-end i7/i9 CPUs (above 10th generation).
- ARGB Lighting Not Working:
- Check if the 3-pin ARGB cable is securely connected to a 5V ARGB header.
- Ensure your motherboard's ARGB software is installed and configured correctly.
- Verify power supply to the ARGB components.
- Temperature Display Not Working:
- Check if the USB 2.0 header cable is securely connected.
- Ensure the ALSEYE "BEM" software is installed and running.
- Verify the cooler's orientation; incorrect orientation might affect display visibility.
- Fan Noise:
- Check for dust buildup on fan blades.
- Ensure no cables are touching the fan.
- Adjust fan speed curves in BIOS/software if noise is excessive at idle.
