4. Installation Guide
Before starting, ensure your system is powered off and unplugged. Refer to your motherboard manual for specific CPU socket details.
4.1 Prepare the Motherboard
- Remove your existing CPU cooler.
- Clean any old thermal paste from the CPU surface using isopropyl alcohol and a lint-free cloth.
- For Intel sockets, install the universal backplate onto the rear of the motherboard, aligning the holes with the CPU socket mounting holes.
- Insert the appropriate standoffs through the motherboard mounting holes from the front side.
4.2 Apply Thermal Paste
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.
4.3 Mount the Cooler
- Attach the correct mounting brackets for your CPU socket (Intel or AMD) to the base of the cooler. The new buckle iteration design ensures a closer fit and improved heat conduction.
- Carefully place the cooler onto the CPU, aligning the mounting holes on the brackets with the standoffs on the motherboard.
- Secure the cooler by tightening the screws in a diagonal pattern until snug. Do not overtighten.
- The twisted neck heat pipe design ensures that the cooler does not block memory slots, allowing for comprehensive display of memory (including light effects) and easy installation without removing the fan.

4.4 Connect Cables
- Connect the 4-pin PWM fan cable to the "CPU_FAN" header on your motherboard.
- Connect the 5V-3pin ARGB cable to a compatible 5V-3pin ARGB header on your motherboard. The male and female design allows for daisy-chaining with other ARGB devices.

5. Operation
5.1 Fan Speed Control
The fan speed is controlled via the 4-pin PWM connection to your motherboard. You can adjust fan curves and profiles through your motherboard's BIOS/UEFI settings or dedicated software provided by your motherboard manufacturer. This allows for optimization between cooling performance and noise levels.
5.2 ARGB Lighting Control
The Addressable RGB (ARGB) lighting effects are controlled by connecting the 5V-3pin ARGB cable to a compatible header on your motherboard. You can then use your motherboard's ARGB synchronization software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync) to customize lighting patterns, colors, and synchronize them with other ARGB components in your system. The Mille Layer Mirror Top Cover enhances the light effects, providing a profound and imaginative visual experience.

6. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your CPU cooler.
- Dust Cleaning: Periodically (every 3-6 months, or more often in dusty environments) use compressed air to blow dust out of the heatsink fins and fan blades. Hold the fan blades gently to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- Fan Inspection: Check the fan for any obstructions or signs of wear. Ensure the fan cable is securely connected.
- 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 a fresh layer before re-installation.
7. Troubleshooting
If you encounter issues with your Jonsbo CR-1400 V2 CPU Cooler, refer to the following common problems and solutions:
- Problem: Fan is not spinning.
-
Solution:
- Ensure the 4-pin PWM fan cable is securely connected to the "CPU_FAN" header on your motherboard.
- Check your motherboard's BIOS/UEFI settings to ensure the CPU fan header is enabled and configured correctly.
- Verify that the fan is not obstructed by cables or other components.
- Problem: ARGB lighting is not working or not synchronizing.
-
Solution:
- Confirm that the 5V-3pin ARGB cable is correctly connected to a compatible 5V-3pin ARGB header on your motherboard. (Note: Do NOT connect to a 12V-4pin RGB header, as this can damage the LEDs).
- Install and configure your motherboard's ARGB synchronization software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, etc.).
- Check for any loose connections in the ARGB daisy chain if you have multiple devices connected.
- Problem: CPU temperatures are high.
-
Solution:
- Ensure the cooler is securely mounted to the CPU and the mounting screws are tightened evenly.
- Verify that thermal paste was applied correctly and adequately. Re-apply if necessary.
- Check that the fan is spinning in the correct direction, pushing air through the heatsink.
- Ensure adequate airflow within your PC case.
- Problem: Excessive noise from the cooler.
-
Solution:
- Check for any cables or obstructions hitting the fan blades.
- Adjust the fan speed curve in your motherboard's BIOS/UEFI or software to reduce RPM at lower temperatures.
- Ensure the cooler is mounted securely and not vibrating against other components.
8. User Tips
- Compatibility Check: Always double-check the cooler's dimensions (133mm height, 92mm width, 70mm thickness) against your PC case's CPU cooler clearance and RAM height before installation, especially for mini-ITX or compact builds.
- Thermal Paste Application: While a pea-sized dot is standard, some users prefer a thin line or cross pattern for larger CPUs. The goal is even coverage without excess.
- Cable Management: Route the fan and ARGB cables neatly to avoid interference with fan blades and to improve overall airflow within your case.
- BIOS Updates: Ensure your motherboard's BIOS/UEFI is up to date to ensure proper recognition and control of fan speeds and ARGB lighting.
