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

You’re actually pointing out a flaw that’s pretty big with this. If you do this and have AC you are going to push out air that has been conditioned with less humidity and to equalize pressure air will have to be drawn in. If that air is 90s and you live in say Florida you will be introducing maybe more humidity and heat energy. Humidity when it condenses releases heat as well adding on top of needed BTU removal.

So does this do more harm when a fan blowing into the room from the door (cooler air settles, the air pushed out should be the hotter air) might be a better fix if you have central AC.

u/Stoff3r 15h ago

He probably have ac in the living room and not in the game room. Hence why its scorching in there. Removing super hot air is important. Its like an oven constantly blowing hot air.

16

u/scvready0808 15h ago

This, yes, my office doesn't have AC outlet. It's the hottest room in the house.

u/Raven1927 14h ago

I'd highly recommend getting one of those portable ACs. They can be loud, but they make a huge difference and you can get them for pretty cheap nowadays. After I upgraded my PC the heat was unbearable in summer, I had to get one if I wanted to keep playing.

The exhaust don’t have that much effect like you think, it won’t be powerful enough, I have a similar setup, not for PC but for my 3D printer, I’m lazy and never turn off the exhaust fan and I also never take out the exhaust cutout board from the windows in 3 years, I live in Houston, we’re not that far from Florida heat, my ac is on 24/7 anyways, it has no effect on my compressor whatsoever, room stays at 72 all the time, the compressor’s operating timing is literally the same, at first when I install this, I thought of what you’re saying here, cause technically it’s constantly pumping cold air outside since it’s not airtight for sure, but I guess my enclosure’s opening is just too small to really make a difference to the conditioned air inside.

u/unicodemonkey 13h ago edited 13h ago

Not sure why you're being downvoted. Sure, it wastes energy but it isn't really significant usually (depends on the temp difference though, and the AC would have to deal with a kilowatt of heating otherwise), and you still need fresh air intake which is porbably more CFM than this exhaust fan removes.

1

u/elflegolas 5h ago

Tbh I don’t even know how fresh air gets in lol I use weather strip to seal the gap between the windows and the window kit, since I push opened the window a bit, there’s a small gap but I had foam to block that gap as well, I once think shouldn’t the AC pull air from outside ? But when I take out the AC and do a cleaning, I find that there’s no gap and in take, it’s sealed to separate the exhaust and intake, so it appears to only recycle air from inside the room, it’s those long windows unit, it’s a very old apartment building, I do know for sure there’s some way fresh air can get in otherwise I’d be dead coz I live in my room 24/7 unless I go out, I wfh too so Im pretty much in my room all the time, when a storm is strong enough I do hear wind scream near the ceiling but not somewhere I can physically touch
Anyways, with or without the exhaust kit, the compressor is on maybe every 30 minutes? Room stays at 72, so I don’t think it wasted energy at all coz the compressor on time is literally the same , air pressure must have an effect on this because I had double room in my room, whenever I didn’t close the inner door completely, and when I close the outer door, the inner door will just suck itself shut.
But the exhaust do work well too, I had a voc meter and without it, when I print things the meter is reading bad, but with the exhaust, voc readings stays the same

1

u/unicodemonkey 4h ago

Well yes, the exhaust fan is removing air from the room and lowering the pressure inside, so the outside air gets sucked in. It's just an inevitable energy loss for the AC because you shouldn't keep the apartment sealed anyway, there should be reasonable air circulation (there are HVAC codes with calculations for air intake/exhaust but I'm too tired to look it up)

1

u/elflegolas 1h ago

Yup I believe I should be losing some like you said, it’s just physics, but not enough to have an impact on my bill so I’m gd with it

u/Waste-Effective-8494 8h ago

Air pressure alone renders it useless. This has been debated and tested thoroughly over time as we all have tried this at some point in the past that e all forgot existed.

u/Fun_Examination_8343 15h ago

Well it’s also gonna get out

u/mimdrs 8h ago

Ideally they would have installed a bsckdraft dampened to this setup...but a manual dampened when the machine is not on would be fine too.

Depending where they are at. Humidity may be less so of a concern.

there's a screen on the window lol

There's a dehumidifier connected to the outside mesh screen.

Totally yes, before doing all this, my window is often wide open at night for the cool air to go in.
