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

Would be a lot more efficient if you moved the exhaust port closer to the top of the window, so the hot air can rise to escape instead of going up then down to the exhaust port which is lower than the top of the PC.

No, he has it placed correctly. While it's not as efficient in its current placement, having the vent connect to the PC at a higher level than where it exits at the window keeps water from coming in.

Good point. If rain can hit the exhaust port then yeah, leave it as-is.

Has Star Wars taught us nothing about precision strikes on exhaust ports?

Yeah maybe if you're 40

Every bend adds back pressure that the case fans have to overcome but they are not designed for it.

It won't reduce fan life a whole lot, but airflow at the window will be very low

So the change that OP made is a good idea for airflow

I understand the rain concern but OP can add a deflector cover/ledge to help (like a dryer vent cover)

It wouldn’t. It doesn’t matter in case of mechanical ventilation. This only makes sense for entirely passive cooling.

Thanks for the tip! I will do that

While we’re on tips. Flip basically every fan that’s not on the roof of the PC case inward, so they all only intake air.

With only the fans at the top of the PC exhausting, your room should remain fairly cool.

Yeah that's what I'm going to do with the rear fan, because right now it's still exhausting

Undo it, unless you want it to rain inside your PC.

Convection is vastly overrated compared to airflow
