Comment on Optimal PSU fan placement
elDalvini@discuss.tchncs.de 1 month ago
It looks like you would want an even airflow through the whole PSU. The main heat-generating components are using the sides of the housing as a heat sink. I’m guessing the fan is mostly so the air inside the housing doesn’t get too warm, not to cool individual components.
Where is the original air exhaust? If it’s near the bottom of the picture, that would confirm my theory. In that case, I would keep the fan placement as close to original as possible (i.e. the blue square).

The original exhaust was at the bottom roughly where the green square is. Since the psu is mounted vertically and I’m designing a new top plate I was thinking it might be a good idea to mount the fan at the bottom so the it could be using convection to its advantage.
Here’s how the exact model psu looks like Image

Are you 3D printing a new top plate for the psu? Remember that the steel housing also functions to contain the emi generated from the psu components. You could end up increasing electrical noise for other components if your new top plate isn’t conductive and grounded.

I didn’t think of that. Thanks for pointing that out! I guess I can cover the inside in aluminium foil tape to stop the electrical noise
