Guide d'installation
Cette section décrit la procédure d'installation générale. Les étapes spécifiques peuvent varier légèrement selon votre carte mère et le type de socket de votre processeur. Consultez le manuel de votre carte mère pour plus d'informations.
1. Préparez votre système
- Éteignez votre ordinateur et débranchez tous les câbles.
- Ouvrez le boîtier de votre ordinateur.
- Retirez tout système de refroidissement du processeur. Nettoyez soigneusement la surface du processeur pour éliminer l'ancienne pâte thermique à l'aide d'alcool isopropylique et d'un chiffon non pelucheux.
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. Appliquer la pâte thermique
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. Installez le refroidisseur.
- 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.
- Assurez-vous que la connexion est sécurisée.

Opération
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.

Contrôle d'éclairage 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.
PWM Fan Control
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
- Installez le logiciel et suivez les instructions à l'écran.
- Use the software to customize the LED display, monitor system parameters, and potentially adjust fan settings.
Entretien
Nettoyer le refroidisseur
Regular cleaning helps maintain optimal cooling performance.
- Éteignez votre ordinateur et débranchez-le de la source d'alimentation.
- 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.
Fréquence: Nettoyer tous les 3 à 6 mois, ou plus fréquemment dans les environnements poussiéreux.
Réapplication de la pâte thermique
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.
Dépannage
Températures élevées du processeur
- Check Thermal Paste: Vérifiez que la pâte thermique a été appliquée correctement et qu'elle n'est pas sèche. Réappliquez-en si nécessaire.
- Verify Cooler Mounting: Confirm the cooler is securely mounted and making good contact with the CPU.
- Fonctionnement du ventilateur: Check if both fans are spinning. Ensure fan cables are properly connected to the motherboard.
- Débit d'air : Assurez une bonne circulation d'air à l'intérieur de votre boîtier PC.
Ventilateurs non fonctionnels ou éclairage ARGB non fonctionnel
- Connexions de câble : Verify the 7-pin connector is securely plugged into the correct header on the motherboard or ARGB controller.
- Paramètres de la carte mère : Check your motherboard's BIOS/UEFI settings to ensure fan headers are enabled and ARGB headers are configured correctly.
- Conflit logiciel : If using multiple RGB software, they might conflict. Try uninstalling other RGB software or using only one.
L'affichage LED ne fonctionne pas
- Câble de connexion: Ensure the 7-pin connector is fully seated.
- Logiciel: If using the darkFlash control software, ensure it is installed correctly and running. Check for updates.
- Pouvoir: Verify the cooler is receiving adequate power.
