2. Key Features

• Dual-Tower, Dual-Fan Design: Optimizes heat dissipation by utilizing two radiator towers and two 120mm fans, effectively transferring heat away from the CPU.
• 6 High-Efficiency Composite Heat Pipes: Features six Ø6mm nickel-plated heat pipes designed for efficient heat transfer and anti-gravity installation, ensuring robust cooling performance with a D-TDP of 260W.
• High-Performance Fans: Equipped with 120mm fans operating at 600-1600 RPM (±10%), providing an airflow of 72.23 CFM and a low noise level of 22-34 dB(A) (MAX). The fans feature 9 balanced blades, a gathered air inlet, and 8 shock-absorbing silicone cushions for quiet and effective operation.
• High Precision CNC Bottom Surface: The cooler base features a high-precision CNC machined surface for direct contact with the CPU, ensuring fast and efficient heat conduction.
• Integrated Top Panel: A minimalist design top panel covers the sintered ends of the heat pipes, enhancing the overall aesthetic and coherence of the radiator.
• Memory Compatibility: Designed to not block memory slots, supporting memory modules up to 43mm in height. Fan position can be slightly adjusted upwards for improved compatibility with taller RAM or wider chassis.
• Wide Compatibility: Supports Intel LGA 115X/1200/1700/1851 and AMD AM4/AM5 sockets.

4. Setup and Installation

Follow these general steps for installing your Jonsbo CR3000E CPU Cooler. Specific steps may vary slightly depending on your motherboard and CPU socket type. Always refer to your motherboard's manual for detailed instructions on CPU cooler installation.

4.1 Preparation

1. Ensure your computer is powered off and unplugged from the wall outlet.
2. Open your computer case to access the motherboard.
3. Remove any existing CPU cooler. Clean off any old thermal paste from the CPU and CPU cooler contact surface using isopropyl alcohol and a lint-free cloth.

4.2 Mounting Bracket Installation

Identify the correct mounting hardware for your CPU socket (Intel LGA 115X/1200/1700/1851 or AMD AM4/AM5).

• For Intel Sockets: Attach the appropriate backplate to the rear of your motherboard, aligning the holes with the CPU socket mounting holes. Secure the standoffs from the front side of the motherboard.
• For AMD Sockets: AMD motherboard installation typically requires the motherboard's own backplate. Remove the plastic retention clips from the stock AMD mounting system, leaving the original backplate in place. Attach the AMD mounting arms to the standoffs on the motherboard.

4.3 Applying Thermal Paste

Apply a small amount of thermal paste (included) to the center of your CPU's integrated heat spreader (IHS). A pea-sized dot is usually sufficient. Do not spread the paste; the pressure from the cooler will spread it evenly.

4.4 Cooler Installation

1. Carefully place the Jonsbo CR3000E CPU cooler onto the CPU, aligning the mounting holes on the cooler's base with the standoffs/mounting arms.
2. Secure the cooler using the provided screws, tightening them in a diagonal pattern (e.g., top-left, bottom-right, top-right, bottom-left) to ensure even pressure. Tighten until snug, but do not overtighten.
3. Connect the 4-pin PWM fan connector from the cooler to the CPU_FAN header on your motherboard.
4. If your motherboard has an ARGB header, connect the cooler's ARGB cable to it for lighting control. If not, the fans will cycle through colors automatically.

5. Operating Instructions

Once installed and powered on, the Jonsbo CR3000E CPU Cooler operates automatically. The fans will adjust their speed based on the CPU temperature, controlled by the motherboard's PWM signal, to maintain optimal cooling performance.

The integrated fans feature an automatic color-changing effect. If connected to a compatible ARGB header on your motherboard, you may be able to control the lighting effects using your motherboard's RGB software. Refer to your motherboard's manual for details on ARGB control.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your CPU cooler.

• Dust Removal: Periodically (e.g., every 3-6 months), use compressed air to blow dust out of the radiator fins and fan blades. Ensure the fans do not spin rapidly during this process by holding them gently.
• Fan Cleaning: If dust buildup is significant, carefully remove the fans from the radiator (if detachable) and clean the blades with a soft brush or cloth. Reattach securely.
• Thermal Paste: While not frequently required, if you remove the CPU cooler for any reason, it is recommended to clean off the old thermal paste and apply a fresh layer before reinstallation.

7. Troubleshooting

If you encounter issues with your Jonsbo CR3000E CPU Cooler, consider the following common problems and solutions:

• High CPU Temperatures:
  • Ensure the cooler is securely mounted and making proper contact with the CPU.
  • Verify that thermal paste was applied correctly and evenly.
  • Check if the fans are spinning. If not, ensure they are properly connected to the CPU_FAN header.
  • Clean any dust buildup from the radiator fins.
• Fans Not Spinning or Spinning Slowly:
  • Confirm the 4-pin PWM connector is fully seated in the CPU_FAN header.
  • Check BIOS/UEFI settings for fan control to ensure they are not set to a very low RPM or disabled.
• RGB Lighting Not Working/Incorrect:
  • Ensure the ARGB cable (if applicable) is correctly connected to a compatible 3-pin 5V ARGB header on your motherboard. Note: This cooler's fans automatically change colors if not connected to an ARGB header.
  • If connected to an ARGB header, check your motherboard's RGB software for lighting control settings.
• Excessive Fan Noise:
  • Check for any cables or obstructions hitting the fan blades.
  • Ensure fans are securely mounted and not vibrating.
  • Clean dust from fan blades.
