5. Setup and Installation
This section outlines the general installation process. Specific steps may vary slightly depending on your motherboard and CPU socket type. Always refer to your motherboard manual for additional guidance.
5.1 Pre-Installation
- Prepare your system: Power off your computer and unplug it from the power source. Open your PC case.
- Remove existing cooler: If you have an old CPU cooler, carefully remove it. Clean any old thermal paste from the CPU surface using isopropyl alcohol and a lint-free cloth.
- Identify your CPU socket: Determine if your CPU is Intel (LGA 115X/1200/1700/1851) or AMD (AM4/AM5) to select the correct mounting hardware.
5.2 Mounting Hardware Installation
Attach the appropriate backplate and standoffs to your motherboard according to your CPU socket type. The cooler is equipped with all-metal mounting hardware for both Intel and AMD mainstream platforms.

5.3 Applying Thermal Paste
Apply a small, pea-sized amount of thermal paste to the center of your CPU's Integrated Heat Spreader (IHS). The pressure from the cooler will spread it evenly.
5.4 Attaching the Cooler
- Carefully place the cooler heatsink onto the CPU, aligning the mounting screws with the standoffs.
- Tighten the screws in a diagonal pattern (e.g., top-left, bottom-right, top-right, bottom-left) until snug. Do not overtighten.
- Ensure the fan is securely attached to the heatsink.

5.5 Connecting Cables
- PWM Fan Cable: Connect the 4-pin PWM fan cable from the cooler to the CPU_FAN header on your motherboard. This allows for automatic fan speed control based on CPU temperature.
- ARGB Lighting Cable: Connect the 3-pin ARGB cable to a compatible 5V Addressable RGB header on your motherboard. If your motherboard does not have a 5V ARGB header, you may need a separate ARGB controller (not included).

6. Operating Instructions
6.1 Fan Speed Control (PWM)
The Delta A40 ARGB cooler utilizes a 4-pin PWM fan, which allows your motherboard to automatically adjust the fan speed based on the CPU temperature. This ensures optimal cooling performance while minimizing noise during lighter loads. You can typically configure fan curves in your motherboard's BIOS/UEFI settings or through manufacturer-provided software.

6.2 ARGB Lighting Control
The Addressable RGB (ARGB) lighting can be customized through your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync). Connect the 3-pin ARGB cable to the appropriate header on your motherboard and use the software to select various lighting effects, colors, and patterns to match your system's aesthetic.
7. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your CPU cooler.
- Dust Removal: Periodically clean the heatsink fins and fan blades to prevent dust buildup, which can impede airflow and reduce cooling efficiency. Use compressed air or a soft brush.
- Thermal Paste: While not frequently required, if you remove the cooler for any reason, it is recommended to clean off the old thermal paste and apply new thermal paste before reinstallation.
