Setup and Installation
The darkFlash E400 CPU Air Cooler is compatible with Intel LGA1851/1700/1200/115X and AMD AM5/AM4 sockets. Follow these general steps for installation. For a visual guide, please refer to the installation video below.
General Installation Steps:
- Prepare Motherboard: Remove any existing CPU cooler and clean off old thermal paste from the CPU surface.
- Install Backplate: Position the universal backplate on the rear of your motherboard, aligning it with the CPU socket holes.
- Attach Mounting Brackets: Secure the appropriate Intel or AMD mounting brackets to the front of the motherboard using the provided screws and spacers.
- Apply Thermal Paste: Apply a small, pea-sized amount of thermal paste to the center of your CPU's integrated heat spreader (IHS).
- Mount Cooler: Carefully place the E400 heatsink onto the CPU, aligning the mounting holes on the cooler with the standoffs on the brackets. Tighten the screws in a diagonal pattern until snug, ensuring even pressure.
- Connect Fan and ARGB Cables: Connect the 4-pin PWM fan cable to the CPU_FAN header on your motherboard. Connect the 3-pin ARGB cable to a compatible 5V ARGB header on your motherboard.
- Connect USB Cable for Digital Display: Connect the USB 2.0 cable from the cooler to an available USB 2.0 header on your motherboard.
Note: The E400 is designed for compact Micro-ATX gaming layouts. Due to shorter cable lengths in some batches, it is not recommended for full-sized ATX cases.

Operating Instructions
Digital Display Functionality:
The darkFlash E400 features an integrated pixel-style LED digital display on its top cover. This display provides real-time system monitoring information. By default, it may show CPU temperature. The display supports both Celsius and Fahrenheit units.
Intelligent Control Software:
To unlock the full potential of the digital display and customize its output, install the darkFlash control software. This software connects via the USB 2.0 header and allows you to:
- Monitor CPU temperature, load, wattage, frequency, and voltage.
- Monitor GPU status, fan speed, and memory usage.
- Select specific data points to display.
- Enable automatic data rotation on the display.
- Set display themes.

ARGB Lighting Control:
The 120mm PWM fan features 5V 3-pin ARGB lighting. This lighting can be synchronized with compatible motherboard software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion 2.0, ASRock Polychrome RGB) to customize colors and effects, enhancing the aesthetic of your PC build.
Maintenance
Regular maintenance helps ensure optimal performance and longevity of your darkFlash E400 CPU Air Cooler.
- Dust Removal: 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 to prevent damage.
- Fan Inspection: Check the fan for any obstructions or signs of wear. If the fan becomes excessively noisy or stops spinning, it may need replacement.
- Thermal Paste: If you remove the cooler for any reason, it is recommended to clean off the old thermal paste from both the CPU and the cooler's base and apply fresh thermal paste before reinstallation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan not spinning or making unusual noise. | Loose fan cable connection, fan obstruction, faulty fan. | Check 4-pin PWM fan cable connection to CPU_FAN header. Ensure no cables or debris are blocking the fan blades. If issues persist, contact support. |
| Digital display is blank or not showing correct information. | Loose USB 2.0 cable connection, software not installed or running, incorrect software settings. | Verify USB 2.0 cable is securely connected to both the cooler and motherboard header. Install the darkFlash control software and ensure it is running. Check software settings for display configuration. |
| ARGB lighting not working or incorrect colors. | Loose ARGB cable connection, incompatible motherboard header (e.g., 12V RGB instead of 5V ARGB), motherboard ARGB software not configured. | Ensure 3-pin ARGB cable is connected to a 5V ARGB header. Check motherboard's ARGB software for lighting settings. |
| High CPU temperatures. | Improper thermal paste application, loose cooler mounting, insufficient airflow in case, fan not spinning at optimal speed. | Re-apply thermal paste. Ensure cooler is securely mounted with even pressure. Check case airflow and fan speed settings in BIOS/software. |
