We believe that the device's port may have slightly sagged during use due to external force or other reasons, causing misalignment and preventing proper connection of Oculink cables. We recommend that you unscrew the motherboard screws to readjust the position, and then carefully adjust the Oculink interface to ensure the cable connector is aligned flush.

Removing the screws ensures that the Oculink interface on the motherboard is aligned with our port. Once your port can connect the Oculink cable, tighten the screws.

Regarding your question about heat dissipation, please note the following: This mini PC is designed with portability as its core advantage, resulting in a compact internal space. Therefore, under high loads (such as demanding games or multitasking), its heat dissipation capacity is slightly less than that of a traditional desktop PC. This is a common characteristic of mini PCs.

To achieve better heat dissipation, we recommend the following when using it:

• Place the device on a well-ventilated desktop, avoiding placing it in a closed cabinet or where it is obstructed by clutter;

• Regularly clean the dust from the vents and fans;

• If needed, consider using it with a small cooling pad.

Based on the description, this issue may be caused by corrupted Windows system files.

How to avoid this: Please avoid repeatedly powering off or forcibly shutting down your computer during use, or during startup and shutdown, to ensure stable system operation.
