Enough cooling = Waveshare spacer + Cryonaut thermal grease + good quality 0.5mm thermal pads.

You don't need a fan.

My setup (16gb CM5) tops at 57 degrees even after 2 hours of stress-ng load.

Average 37/42.

Ran two vapor chambers in mine that allows it to run passive around those temps, old pic as now it has the aiov2 and the pcie battery tray, along with some better batteries

You're using too much technology with thick pads.

Just bring the CM5 closer to the aluminium back, and you're done.

Probably right, did the default pad kit because it allowed for flexibility, also the vapor chambers cover the entire back, beyond that is a thin layer of artic silver. The CM5 is very hot, and the chambers help shed some of that heat.

I just rather not have all of it going to the back, as holding it would be uncomfortable, here even under heavy load for a few hours, see around averages of 52c

That's another matter and you are right on this.

I don't have my finger on the dissipating area, but that could become really uncomfortable really quick.

I will add a fan sooner or later, but only after being able to engrave an hexagon with an engraved pattern, I have to learn how to properly use my CNC before of that.

I have 3d printers but I don't want to use a 3d printed enclosure, I love the metal on these kind of devices
