A comment on Raspberry Pi 5.

The fins on the active cooler are the wrong orientation (the fan is blowing at the flat sides instead of along it). I'm curious why it was designed this way when so much effort was put into using a proper 4 pin blower fan and header.

It will probably work fine but it's something you notice just like how Dell put the heatsink on the IDRAC card in the R420 the wrong way, which would have significant impacts on airflow and cooling.

Because manufacturing... Otherwise you have to CNC the whole thing and it makes it really expensive.

I suppose you have a point. It was probably extruded along the fins like this (coming straight in/out of screen):

__|||||||___(fan)____

Then they would have to CNC the edges off to create the mounting ears anyway and cut the slots in the fins. I suppose they could just make the gaps larger but this is probably getting into the details...
