Where on the board is the most heat being generated???
Stepper drivers
@Jonathon_Thrumble I’m guessing those are the stepper driver chips closest to the camera! I thought they’d have heatsinks on the chips themselves!
They use the copper in the board as a heatsink, the underside of the chip is where most of the heat comes from hence the deeper sextion on the 2nd pic
I disagree with the original premise of the weight being important. It is the amount of surface interface for both the object to be cooled and the coolant (air/liquid) and the amount of coolant flow. Any mass only has to do with heat dampening. That said, carry on. LOL
@NathanielStenzel more metal mass just works like a heat spreader!..adding the fan helps to dissipate it quicker! Hopefully thermal paste/pad was used intermediately!
@Fook_INGSOC only the thinnest coverage of the surface with a metal or thermal paste is needed to spread the heat. Spreading it into mass is dampening/ballast/storage. Yes, a fan helps dissipate the heat quicker. We may just be using different terms for the same thing. Language is funny that way. Of course, if the chips do not generate the same amount of heat all the time then the thermal mass helps it take longer before it needs to be cooled off so that can reduce the fan throughput needed.
I had considered a cage fan blowing into a tube with fins on the inside of it with the tube connected to the components to be cooled like some big tubular heat sinker on steroids before. I have also considered the same thing but an electronics enclosure instead of a heatsink tube.
Stop screwing around and do it properly. Submerge the whole board in a tank of mineral oil and circulate the oil through a dry ice cooling system.
Let’s revive the spirit of the '90s and overclocking the crap out of Intel 486 computers!
@NathanielStenzel Have you seen Apple’s Mac Pro “Trash Can” cooling system???

Have you unlocked the firmware to get the full 2.8A? I suspect just mounting it vertically and using the chimney effect lets me use 2.4A that the regular firmware enables. Well, really I have a fan on the front side and later I found the docs said to cool the reverse side. Oops.
