Replacement Instructions

45 min
Difficult

Requirements:

A soft surface
– For example, you can use a towel

A small container to store the screws
– Make sure you don’t lose the screws

Heatsink
Screwdriver
Spudger (or a similar plastic tool)
Thermal paste with a spatula
Metal cleaner
Wet wipes
Microfiber cleaning cloth

Place the NUC Box upside down on a soft surface.

This prevents scratches on the NUC Box.

Then remove all screws using the screwdriver.

Pick up the NUC Box and carefully turn it over.

Then grip the top cover at all corners.

Lift it off from the bottom part.

Unscrew the two black screws on both sides.

Disconnect the WiFi antennas from the WiFi module.

Carefully lift the motherboard on both sides and raise it up.

Place the motherboard on a soft surface with the fan facing upward.

Remove the three screws and disconnect the two cables. Note: the two screws on the right side do not fully come out of the component.

Then carefully lift the fan off the motherboard.

Carefully remove the screws from the heatsink.

Gently move the heatsink to check if it is loose.

Carefully lift the heatsink on both sides. It may feel slightly stuck due to the sticky thermal paste.

Remove the old thermal paste from the heatsink.

Use the spatula for this. Afterwards, use wet wipes to remove any remaining thermal paste.

To fully clean the heatsink, use the microfiber cloth with metal cleaner.

Apply a small amount of thermal paste to the spatula.

Spread the thermal paste evenly over the CPU.

Make sure you no longer see any reflective surface on the CPU.

Carefully place the new heatsink in position.

Make sure not to shift the heatsink after placing it down.

Tighten the heatsink screws.

Place the new fan in the correct position.

Tighten the screws.

Carefully reconnect the cables. They only fit one way.

Place the motherboard back at a slight angle and gently press it into the correct position. Make sure the WiFi antennas remain above the motherboard.

Reconnect the WiFi antennas to the WiFi module.

Secure the motherboard by tightening the two black screws.

Place the bottom of the NUC Box back into position.

Make sure the arrow labeled “front” is pointing toward the actual front of the device.

You can verify this by slightly lifting the NUC Box at the front.

Use the screwdriver to fasten the screws back into place. Note: do not overtighten the screws. Overtightening may make it difficult to remove them again in the future if needed.

The new bottom cover is now installed.

Well done!
