If you notice that your item is warm, try the following troubleshooting steps.
Firstly, check if the temperature rise is within the normal range (lower than 25℃ / 77°F) when using this hub. If so, it is considered normal.
If the temperature rise is more than 25℃ / 77°F when using this hub, it is considered abnormal. In this case, confirm if the hub works properly when it gets hot and whether the abnormal temperature rise occurs under full load.
Finally, try using this item with a different laptop and different working peripheral devices to determine if the issue persists.
