Setup and Installation
Follow these steps for proper installation of your darkFlash DE360 liquid CPU cooler. Ensure your system is powered off and unplugged before beginning.
1. Prepare the CPU Block
- Carefully remove the protective film from the copper cold plate of the CPU block.
- Attach the appropriate mounting bracket (Intel or AMD) to the CPU block. Align the bracket with the arrows and rotate until it is parallel and securely locked.

2. Install Radiator and Fans
- Mount the 360mm radiator with its pre-installed fans to an available fan mounting location in your PC case (typically the top or front). Use the provided screws to secure it.
- Ensure proper airflow direction for optimal cooling.

3. Mount the CPU Block
- Apply a small amount of thermal grease to the center of your CPU's integrated heat spreader (IHS).
- Place the backplate on the rear of your motherboard, aligning it with the CPU socket holes.
- Insert the appropriate standoffs (Intel 17XX/115X/1200 or AMD) into the four mounting holes around the CPU socket.
- Carefully place the CPU block onto the CPU, ensuring the mounting holes align with the standoffs.
- Secure the CPU block with the provided mounting screws, tightening them in a diagonal pattern until snug. Do not overtighten.

4. Cable Connections
- Connect the 3-pin pump connector to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the fan PWM cables to the CPU_FAN or other available fan headers on your motherboard.
- Connect the ARGB cables to a compatible 5V 3-pin ARGB header on your motherboard for lighting synchronization.
- Plug the USB 2.0 connector from the LCD screen into an available USB 2.0 header on your motherboard. This is essential for LCD display functionality and software control.

Operating Instructions
Once installed and connected, the darkFlash DE360 will begin cooling your CPU automatically. The fans will adjust speed based on CPU temperature via PWM control.
LCD Screen Functionality
The 2.88-inch IPS LCD screen on the CPU block displays real-time system information such as CPU temperature, frequency, and other customizable data. It can also display custom images or videos.

Software Control and Customization
To fully utilize the LCD screen's customization features and monitor system performance, download the dedicated darkFlash control software from the official darkFlash website. The software allows you to:
- Monitor CPU and GPU temperatures, fan speeds, and other system parameters.
- Select from various pre-designed themes for the LCD display.
- Upload custom images or videos to be displayed on the LCD screen.
- Adjust display rotation (e.g., 90 degrees) for optimal viewing angles.

Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your liquid CPU cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fans using compressed air. Ensure the fans are not spinning during cleaning to prevent damage.
- Tube Inspection: Check the coolant tubes for any signs of kinks, leaks, or damage. Ensure they are not pressing against other components that could cause wear.
- Pump Noise: Listen for unusual noises from the pump. A consistent humming sound is normal, but grinding or gurgling may indicate an issue.
- Thermal Paste: While not frequently required for AIOs, if you ever remount the CPU block, clean off old thermal paste and apply new thermal paste for optimal heat transfer.

Troubleshooting
If you encounter issues with your darkFlash DE360, refer to the following common problems and solutions:
- High CPU Temperatures:
- Ensure the CPU block is securely mounted and making full contact with the CPU.
- Verify that thermal paste was applied correctly.
- Check if the pump is running (listen for a faint hum or check software monitoring).
- Ensure radiator fans are spinning and oriented correctly for airflow.
- Clean any dust buildup on the radiator fins.
- Fans Not Spinning/RGB Not Working:
- Check all fan and ARGB cable connections to the motherboard.
- Ensure the ARGB header on your motherboard is enabled in the BIOS/UEFI or motherboard software.
- Confirm that the power supply is providing adequate power.
- LCD Screen Not Displaying:
- Verify the USB 2.0 cable from the LCD screen is securely connected to both the CPU block and the motherboard header.
- Install the darkFlash control software and ensure it recognizes the device.
- Check for any driver updates for the cooler on the darkFlash website.
- Unusual Pump Noise:
- Ensure the pump is positioned lower than the highest point of the radiator to prevent air bubbles from accumulating in the pump.
- If the noise persists, contact darkFlash support.
