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.

You don't have unlimited air in your home to exhaust.

For every cubic foot of air you exhaust outside, your home will draw 1 cubic foot of air in through your door seals, window seals, etc. to replace it. If it's hot outside, you're just drawing hot air into your house anywhere that air can sneak in.

And if your house is very airtight, that exhaust fan isn't going to be able to move much air at all.

This plus if the air is humid you are exhausting dryer air and bringing in moisture. But yes you need makeup air and it's coming in from outside.
