My question is about heat. By doing this, aren't you dramatically affecting how well the heat sinks work? The heat would travel up and get stuck on the board.
Maybe it's not an issue, but it has me worried, so I thought I would ask how yours is working.
Yes, you are correct that the heat would travel up and get stuck on the board… in a closed box
The heat can simply not escape and will definitely accumulated in the enclosure, since there is no air convection.
But as long as there is sufficient air convection (air flows bottom => top), it should be fine.
The heat does travel up and then coming out the enclosure via the tube holes (28mm dia) and the vents on top of the enclosure.
The enclosure I used is very well ventilated (vents on both top and bottom).
On top of that, I have made 4 extra holes with 20mm diameter on the bottom plate, right under the area of the heatsinks.
By doing so, cold air can enter the enclosure exactly where it needed most.
The invisible hand of Mother Nature does the remaining part of the cooling job.
