Guia de instalação
This section outlines the general installation process. Specific steps may vary slightly depending on your motherboard and CPU socket type. Refer to your motherboard manual for additional guidance.
1. Prepare seu sistema
- Desligue o computador e desconecte todos os cabos.
- Abra o gabinete do seu computador.
- Remove any existing CPU cooler. Clean the CPU surface thoroughly to remove old thermal paste using isopropyl alcohol and a lint-free cloth.
2. Install Backplate (Intel/AMD)
Identify the correct backplate and mounting screws for your CPU socket (Intel LGA1851/1700/1200/115X/1366 or AMD AM5/AM4).
- Position the backplate on the rear side of the motherboard, aligning the holes with the CPU socket mounting holes.
- From the front side of the motherboard, insert the appropriate standoffs through the mounting holes and secure them to the backplate.
3. Aplique a pasta térmica.
Apply a small, pea-sized amount of thermal paste to the center of your CPU's Integrated Heat Spreader (IHS). Do not spread it manually; the pressure from the cooler will distribute it evenly.
4. Monte o cooler
- Carefully place the E400 Plus cooler onto the CPU, aligning the mounting holes on the cooler's base with the standoffs.
- Secure the cooler using the provided mounting screws. Tighten screws in a diagonal pattern (e.g., top-left, bottom-right, top-right, bottom-left) until snug. Do not overtighten.
- The front fan can be removed for easier installation if needed, then reattached.
5. Connect Fans and ARGB
The E400 Plus features a 7-pin connector for simplified cable management.
- Connect the 7-pin cable from the cooler to the designated header on your motherboard or ARGB controller. This cable typically handles both fan power (PWM) and ARGB lighting.
- Certifique-se de que a conexão seja segura.

Operação
Real-Time LED Digital Display
The top of the E400 Plus features a pixel-style LED display that shows your CPU temperature in real-time. This display can show temperatures in both Celsius and Fahrenheit.

Controle de iluminação ARGB
The dual 120mm fans feature Addressable RGB (ARGB) lighting.

- If connected to an ARGB header on your motherboard, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome RGB).
- If connected to a dedicated ARGB controller (not included), refer to the controller's manual for lighting adjustments.
Controle de ventoinha PWM
The fans are Pulse Width Modulation (PWM) controlled, allowing your motherboard to dynamically adjust fan speed based on CPU temperature. This optimizes cooling performance while minimizing noise.

- Ensure the 7-pin connector is properly connected to a CPU_FAN or similar header on your motherboard.
- Adjust fan curves in your motherboard's BIOS/UEFI settings for optimal performance and acoustics.
Intelligent Control Software
darkFlash provides optional software for enhanced control over the LED display and monitoring.

- Download the software from the official darkFlash website: https://www.darkflash.com/driver
- Instale o software e siga as instruções na tela.
- Use the software to customize the LED display, monitor system parameters, and potentially adjust fan settings.
Manutenção
Limpando o refrigerador
Regular cleaning helps maintain optimal cooling performance.
- Desligue o computador e desconecte-o da tomada.
- Carefully remove the fans from the heatsink.
- Use compressed air to blow dust out of the heatsink fins. Hold the can upright and use short bursts.
- Clean fan blades with a soft cloth or cotton swab.
- Reattach the fans securely.
Freqüência: Clean every 3-6 months, or more frequently in dusty environments.
Reaplicação de pasta térmica
Thermal paste can degrade over time. Reapplying it every few years can improve thermal transfer.
- Follow steps 1-3 from the "Prepare Your System" section of the Installation Guide.
- Clean off old thermal paste from both the CPU and the cooler's base.
- Apply new thermal paste as described in the "Apply Thermal Paste" section.
- Reinstall the cooler.
Solução de problemas
Altas temperaturas da CPU
- Verifique a pasta térmica: Ensure thermal paste was applied correctly and is not dried out. Reapply if necessary.
- Verify Cooler Mounting: Confirm the cooler is securely mounted and making good contact with the CPU.
- Operação do ventilador: Check if both fans are spinning. Ensure fan cables are properly connected to the motherboard.
- Fluxo de ar: Garanta uma circulação de ar adequada dentro do gabinete do seu PC.
Fans Not Spinning or ARGB Not Lighting Up
- Conexões de cabo: Verify the 7-pin connector is securely plugged into the correct header on the motherboard or ARGB controller.
- Motherboard Settings: Check your motherboard's BIOS/UEFI settings to ensure fan headers are enabled and ARGB headers are configured correctly.
- Conflito de software: If using multiple RGB software, they might conflict. Try uninstalling other RGB software or using only one.
Tela LED não funciona
- Conexão à cabo: Ensure the 7-pin connector is fully seated.
- Programas: If using the darkFlash control software, ensure it is installed correctly and running. Check for updates.
- Poder: Verify the cooler is receiving adequate power.
