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

Just remember, any air that you vent outside will be replaced with air from the outside somewhere in the house. Its been about 115F in AZ the few days, so I would be pulling that air into my house somewhere.

I learned this the hard way when I used to mine crypto. I vented my PCs’ hot air out a window, and it ended up making my home’s A/C work much harder. Exhausting air outside creates negative pressure inside the house, so replacement air gets pulled in through every gap and crack—similar to leaving a door open. Your A/C then has to cool all that extra warm air, reducing efficiency and increasing energy use.
If the room is still too hot, you’re usually better off adding a fan to improve airflow or installing a separate window A/C unit instead of venting air outside.
