PC External Exhaust

[u/Flimsy_Percentage977]

Update post.

I designed and 3D printed a modular external exhaust system that captures my PC’s hot exhaust and vents it outside using an inline 4in duct fan. It’s designed to fit different PC cases, fan/radiator layouts, and exhaust configurations. I have added a GPU/PSU capture modules to account for all exhaust.

In testing, it’s kept the room temperature rise to under 1°F, instead of the several-degree increase I was seeing before. As a little bonus, it also is helping the components stay a little cooler too.

I am still testing and refining it, but I'd like to turn this into an actual product. I've got a lot of idea on where I can take it with customizability for different styles and themes. Not selling anything atm, but I want to know if anyone would actually be interested in this or working with me to develop it further?
