FAQs
Does the A400i come with thermal paste?
Yes, it is recommended to use the provided thermal compound or a high-quality alternative during initial installation.
Can I turn off the RGB lighting?
The lighting is automatic and integrated into the fan; there is no software interface to disable it.
Will this fit in an Intel LGA 1700 build?
Yes, the A400i supports LGA 1700 out of the box with the included mounting hardware.
How do I control the fan speed?
Fan speed is controlled automatically by your motherboard via the 4-pin PWM connector based on the CPU temperature.
Is this cooler compatible with AMD AM4 sockets?
Yes, it fully supports the AMD AM4 platform.
Troubleshooting
Fan is spinning at full speed constantly
Enter your BIOS settings and ensure the 'CPU Fan Control' or 'Smart Fan' mode is set to 'PWM' rather than 'DC' or 'Manual'.
Excessive noise or rattling
Verify that the cooler is mounted tightly and that the fan is securely snapped into the fan clips. Check that no cables are brushing against the fan blades.

Setup, Compatibility & Care
Before installation, verify that your motherboard socket is supported (e.g., LGA 1700 or AM4). Ensure your case has at least 155mm of clearance from the motherboard to the side panel.
- Prepare the backplate and mounting brackets according to your specific socket type.
- Apply a pea-sized amount of thermal compound to the center of the CPU.
- Secure the cooler using the provided metal fasteners, tightening screws in a diagonal pattern to ensure even pressure.
- Connect the 4-pin fan cable to the `CPU_FAN` header on your motherboard.
For care, use compressed air every 3-6 months to clear dust from the aluminum fins to maintain optimal heat transfer efficiency.
