Noises that may originate from your Intel NUC

  • When the fan turns, it makes grinding noises, similar to worn ball bearings.
  • There is a knocking and ticking sound as if a fan blade has collided with something.
  • Squeals from the fan.
  • Rattling noise that is quite loud.

Easy tips on eliminating Intel NUC fan noise

1) Adequate ventilation

Make sure there is enough space for airflow around your Intel NUC to ensure it has adequate ventilation. Good airflow may help to alleviate the problem of the Intel NUC overheating. Prop your device up and place it at eye level to allow for proper airflow to prevent it from overheating.

2) Clean the Intel NUC fan and vents

Often, a noisy Intel NUC fan is a dirty fan. As dust accumulates, it stops the fans from cooling the sensitive internal components of your device as effectively as they should. Ensure you eliminate dust from the fans and vents regularly to ensure that your device cools itself adequately.

  • Before cleaning it, turn down your gadget and unplug all cords and connections, including the power cable.
  • If possible, open your Intel NUC and clean the CPU fan directly. To eliminate any dust buildup, spray the fans with compressed air in short bursts and clean them down with a microfiber cloth.
  • While still there, use compressed air and the microfiber cloth to clean the power supply fan. Power supply fans become loud if they are too dirty to function correctly. Avoid opening the power supply, but ensure you clean it as thoroughly from the outside.
  • Finally, examine the thermal paste on the device’s CPU and any other components that may contain it. Thermal paste aids in the passage of heat from your CPU and GPU to their respective heat sinks, but it can deteriorate with time to become less effective. Replace any aging or worn-down thermal paste.

Before you shut down your device, confirm that you’ve reconnected all of your fans to the motherboard – if you don’t, they won’t function at all.

3) BIOS update

Perform an automatic BIOS update to see if there are any newer versions of the BIOS available. Intel NUC provides updates for the BIOS as well as for some other components of your device. Software updates should be checked for.

4) Consider a software fix

With third-party software, most Intel NUCs allow you to change the fan speed. Controls are included in specific models. Typically, these features enable users to adjust the fan speed on their machines or initiate a cleaning cycle to eliminate dirt and dust.

Thus, ideally, you should be able to lower the amount of noise produced by the fan by decreasing its speed. Keep in mind that this can increase the temperature of your gadget, which will shorten its overall lifespan. Therefore, extra caution should be exercised when utilizing the software.

5) Check and replace the Intel NUC fan

Users will occasionally need to perform maintenance on their gadgets.  If it’s anything simple like replacing the Intel NUC fan, one can usually handle it oneself. As fans are one of the few moving parts in the Intel NUCs, they are frequently the first component to fail. However, replacing the Intel NUC fan is usually a straightforward process, as elaborated in this article.

Before you begin, it is essential to ensure that you operate on an electrostatic discharge (ESD)-safe workstation and disconnect the power supply. Failure to work on an ESD-safe workstation ESD can damage your components.

If there is advice that will make disassembly and reassembling computer components easier, videotape the procedure. This makes it simpler to recall the screws that were removed and which lead should be plugged in where. Below are the steps to follow to replace your fan;

  • Unplug the screws that secure the rear plate to the chassis.
  • Disconnect the VGA cable from the frame. If you do not, you will have difficulty subsequently removing the board.
  • All cords attached to the board should be disconnected. This comprises the drive enclosure cords, front display, and the Wi-Fi card’s antenna lines.
  • Remove the screws that secure the motherboard to the frame.
  • Carefully yield the board from the front side. It will emerge at an angle, with the USB ports being the last to emerge.
  • Reverse the board and set it on a soft surface, such as a cushion or a soft microfiber.
  • Remove the fan power supply cable from the motherboard and the two support screws.
  • Disconnect the fan.

After removing the Intel NUC fan, it can be swapped by simply reversing the process. This is when your video can be advantageous. If you are unable to record the procedure, below are the steps in reverse to replace the fan;

  • Reinstall the fan and secure the board’s fasteners.
  • Reattach the fan’s power cable to the circuit board.
  • To reinstall the board, make sure it’s orientated correctly, angle the board’s rear ports into place, and lightly slide the panel into place.
  • To reconnect the board to the chassis, reinstall the board screws.
  • Tweezers are used to hold the antenna wire to the Wi-Fi card in contact. Carefully press down till they click.
  • Reconnect all loose leads and cords.
  • Connect the VGA cable to the frame.
  • The drive cage should be reinstalled.
  • Replacing the screws will allow you to return the rear panel.

By now, the fan has been successfully replaced. It is essential to be careful not to damage your Intel NUC when replacing the fan so as not to void the gadget’s warranty.
