Extra Cooling for AD03 - Air Flow Direction

[gianluoperation]

Good morning,
I'm installing an additional fan pad for my AD03 that I would place above the "external fan" (as shown in the photo) but since the AD03 minipc has its own internal heat sink and a vent underneath I'm not sure whether to install it blows air or sucks air . (not knowing how the internal fan works). Do you have any suggestions?

You can usually tell when letting it run, and holding your hand up to it. For example, on my AD03, the bottom fan blows out (away from the system).

You can also try using something very light, like a piece of tissue, in front of the fan.

After the test seems that the air is sucked in from below to exit from the side vents...
