Extended Product Information

FAQs

Does this cooler fit in an ATX mid-tower case?

Most ATX mid-tower cases support 162 mm coolers, but please check your specific case specifications for CPU cooler clearance.

Is the LCD display customizable?

The display is designed to show live processor telemetry; please refer to the product software suite if applicable for potential configuration options.

Can I use this with an AMD AM5 processor?

Yes, the cooler includes mounting hardware compatible with AMD Socket AM5.

What is the noise level at full load?

The fan generates approximately 25.6 dB at high speeds, which is relatively quiet for its cooling performance class.

Does it come with thermal paste?

Yes, it typically includes the necessary mounting hardware and thermal interface material required for installation.

What happens if the fan fails?

The fan uses a high-quality Sealed Precision FDB, but if it fails, the unit features standard 120 mm mounting points for easy replacement.

Troubleshooting

LCD screen is not displaying information

Verify that the 9-pin cable is properly seated in the motherboard's internal USB header.

Fan is running at maximum speed constantly

Check your BIOS settings to ensure the fan header is set to PWM mode instead of DC or Auto.

Higher than expected CPU temperatures

Re-check thermal paste application and ensure the cooler mounting pressure is even across all four corners.

Pros and Cons

Pros

  • Integrated live CPU telemetry display
  • Excellent heat dissipation with six-pipe dual-tower design
  • Quiet operation with FDB fan technology
  • Modern, stealthy all-black aesthetic
  • Wide compatibility with current Intel and AMD sockets

Cons

  • Height of 162 mm may limit compatibility with some smaller cases
  • Requires 9-pin internal connection for LCD functionality
  • Dual-tower bulk can interfere with tall RAM modules

Setup, Compatibility & Care

To ensure proper installation, verify that your computer case supports a cooler height of at least 162 mm. During setup, apply high-quality thermal paste to the center of your processor before mounting the heatsink towers. When connecting the device, ensure the 9-pin cable is securely fastened to an internal header on your motherboard to enable the LCD telemetry functionality. For maintenance, use compressed air to clear dust from the heatsink fins and the fan blades every 6 to 12 months. Ensure the fans are oriented to push air toward the rear exhaust of your case for optimal airflow efficiency.
