Summary

This is custom top shell for Aoostar GOD and Tianbei MN5X mini PCs. And probably other brands that use the same supplier.

Mine is Aoostar GOD78 with Ryzen 7 7840H. While it works OK as is, when you push CPU a bit it heats up to 86+ °C, starts to thermal throttle and, what's worse, fan ramps up to 2500 rpm and is quite audible.

When I took the top off it didn't thermal throttle and fan didn't go above 1250 rpm.

So I designed custom top shell that has a bit more ventilation.

There are three versions, first one is original size, second is 2mm higher and last one is 5mm higher.
Reason is that with original sized one it still occasionally ramped the fan up to 2500 rpm for few seconds under heavy load.

In the end I went with 5mm higher and now it doesn't exceed 1250 rpm.

But depending on CPU in your mini PC original or 2mm version might be enough.

I also made three versions of each, one is with hex cutout mesh, second one is without so if someone wants to remix it with some other pattern feel free.
Last one is without side cuts so you can customize everything.

I made this with FreeCAD so I also included files with FreeCAD parts.
