This Asus N82J laptop has been following me around since 2010 (I know...) and one of it's issues (as with most laptops and notebooks) is cooling performance.
Air exiting from the exhaust was always hot (convenient during winter) and there are no visible air intakes.
To improve this, I removed the plate that covers RAM on the middle of the laptop's bottom, put whatever thing under the bottom to raise clearance and called it a day. And it worked!
We all know what follows: I have a 3D printer... I have FreeCAD and Cura on this laptop... lets do this properly!
And so I did. The stands are pretty solid and stealthy, they sort of hug the lid and it's hinges. The RAM plate has multiple slots for proper intake air flow.
The result: Higher screen height, less noise from the fan, better performance on longer high demand tasks and it no longer burns whatever is sitting next to the exhaust.
I know these files are probably useless (unless you also still rock your N82J) but hey, you can also do something similar for your laptop.
The FreeCAD files are also included if you need to make modifications.
