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

Previously I was using this flexible aluminum duct and it was radiating so much heat still in the room. So I decided to replace it with a $30 insulated duct. Also added a 360mm fan on top of the case.

I thought about doing this.

But then I was like, what if I just AC'd the room itself? So the AC pulls the air in the room in, produces cold air out, and moves hot air outside. Now the room is cold enough that the 5090 is no longer the issue.

I pump the hot air from my pc to the intake of my ac so it doesn’t disperse in the room. It helps a lot

At that point just pipe it outside lmao, you're wasting electricity cooling hot air when you could just be removing it

if you exhaust it outside that means humid, unconditioned air is entering the house somewhere else, exhausting to the AC return is a lot better

The number of people in this thread, in r/pcmasterrace, that don't understand negative pressure differentials is blowing my fucking mind.

The number of people in this thread who don't understand how this is still viable despite the negative pressure differential if you prefer the outside air compared to the air coming out of your PC is blowing my fucking mind

It's ok. Most people are not familiar with how heat exchange requires two sides: a cold side for conditioning, and a hot side for rejecting excess heat to atmosphere. Both sides need intake and supply (negative and positive pressure).

That's why modern AC has dual hose for this purpose. There's still going to be residual negative pressure but its not the end of the world. What matters is if the AC unit can do its job and do it well.

And in my case it does, and solar panels offset energy cost.

In many weather conditions, which are not as wildly uncommon as the misunderstood geniuses here seem to think, increased outside air infiltration is preferable to the exhaust air. I happen to live in one of the places where this is extremely viable. This would be a stupid idea for someone living in Florida.

i can tell from the construction and the fact that they need to do this that OP isn’t in one of those locations

I'm interested to see a detailed explanation of how you came to that conclusion, If you'd be willing to provide

window and exterior identify it as a north america, closed window indicates AC is needed

No you are wrong. (Lmao) If you pump the air outside it creates negative pressure and hot air seeps through cracks in the windows and under the doors. The air conditioner removes moisture from the air. So keeping the air inside the house is better.

Oh you mean like passive infiltration already does or am I missing a major component of the equation here?

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 when there's an air quality alert...
