Extended Product Information

FAQs

Does this cooler come with thermal paste?

Yes, thermal compound is included in the packaging for initial installation.

Can I remove the front fan?

Yes, the fans are removable, which can help with RAM compatibility or cleaning.

Is this compatible with LGA 1851?

Yes, the cooler is fully compatible with the LGA 1851 socket.

How loud is the cooler under load?

At maximum speed, the noise level is approximately 25.6 dB, which is considered very quiet for a dual-tower air cooler.

Can I control the LED display brightness?

Brightness and color settings are generally managed through your motherboard's lighting software.

Does the cooler block RAM slots?

Due to its large size, it may overhang the first RAM slot. Low-profile memory is recommended for the best fit.

Troubleshooting

Fan is making clicking or grinding noises

Check that the fan is not obstructed by cables and that the frame is correctly seated on the heatsink.

ARGB lighting is not working

Verify the 3-pin ARGB cable is securely plugged into the motherboard's 5V ARGB header and not a 12V RGB header, which could damage the lights.

CPU temperature remains high

Ensure thermal paste was applied correctly, the cooler is tightened evenly, and the fan is responding to BIOS PWM settings.

Pros and Cons

Pros

  • Excellent cooling performance for its price point
  • Quiet operation thanks to high-quality FDB fans
  • Sleek black aesthetic suitable for any build theme
  • Includes digital monitoring display
  • Broad compatibility with current Intel and AMD sockets

Cons

  • Large 162mm height requires spacious PC cases
  • Dual-tower design may interfere with tall RAM modules
  • Installation can be slightly more involved than single-tower coolers

Setup, Compatibility & Care

Installation requires a Phillips-head screwdriver and careful alignment with the provided mounting brackets. Always ensure the backplate is securely fastened to the motherboard for your specific socket type (Intel or AMD).

  • Compatibility: Check your motherboard's socket type before installation; it supports LGA 115x, 1200, 1700, 1851, and AM4/AM5.
  • RAM Clearance: Measure your RAM height; the front fan may need to be adjusted upwards if you are using tall, RGB-lit memory modules.
  • Maintenance: Every six months, use compressed air to clear dust from the heatsink fins and fan blades to maintain optimal airflow.
  • Connections: Plug the 4-pin PWM cable into the `CPU_FAN` header on your motherboard and the 3-pin connector to your ARGB header for full functionality.
