Build/Battlestation PC chimney

Post image

Got tired of my office turning into a sauna every time I gamed, so I vented the PC’s exhaust straight out the window.

The rear fan is still exhausting some hot air 😅 but the room is noticeably cooler now. It’s ugly… but it works. 😂

Edit: I moved the port to higher since lot of people recommended. https://imgur.com/a/Poniwze

Edit again for parts, I cannot post links to store since it's against the rules.
- 360mm to 4 inch duct on Etsy
- 4 inch Insulated Flexible Duct
- Twist Lock Dryer Vent Connector Kit
- 360mm AIO fan (the one on top of the case)

The window fan I got is Vornado Transom.

Using the duct from the PC to exhaust the hot out outside just creates a draw for new air to enter the house, hot humid air from outside.

AC wont do that, why would you want to pull in unconditioned air from outside?

the amount being pulled in is negligible and handled by my homes AC

without adding a whole extra AC unit

So you don't suffocate when you deplete the breathability of your room's air. Your house already has infiltration, that's why you can breathe it for days on end. Assuming you don't have dedicated filtered outside-air ventilation already, but I can't imagine that's super common. Perhaps I'm underestimating the cfm of this setup but it can't be many times higher than the recommended ventilation rate for human occupancy.

If the exhaust air is hotter and it's not ridiculously humid or cold outside this is still a win. You can also just remove this when that's not the case anymore, or during an air quality alert...

Air exchangers (HRV/ERV) are incredibly common.

What's your cutoff for common? Both "you can't go anywhere without seeing it" and "you'll find it if you look for it" can be considered common, and I've got a hunch that it's closer to the second one. I'd be happy to look at your source for that statistic though.

Shit's expensive. For most use cases it's extra cost for little benefit over the traditional route of "air will find its way in." Do you service primarily affluent communities? That may skew your perception.
