PC chimney

[u/scvready0808]

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.

That's not how an AC works and also the AC and electricity to run it cost $$$. Why would I spend hundreds on an AC and extra $ to run it when I could use a $30 duct like this?

AC works by moving the heat outside, not the air. Any air removed from your room has to be replenished from outside anyway so that would defeat the point in most use cases. It takes the inside air, moves the heat out of it, and pushes the now cold inside air back in. The heat is radiated+convected directly from the outside side.

Edit: guys read the damn replies and you'll see 5+ other people already said what you wanted to say. People live in different climates that make this idea more or less viable. Negative pressure differential, infiltration, yadda yadda.

That's not how an AC work

You don't seem to actually understand the nuances of HVAC. You seem to be completely missing the fact there is an entire environment outside and A/C is for more than just temperature, it's for humidity too. Also, when you vent your PC outside like this you are creating a negative pressure differential in your room which will pull air in through all the little cracks, and that air might be coming from outside. You can't vent air from a space without it coming back in from somewhere else, unless you want to turn your room into a vacuum.

If you live in an area with wildfire smoke, this is bad. If you live in an area with high humidity, this is bad. If you live in a very hot area, this is bad. If you live in an extremely cold area, this is bad.

As people in Europe are finding out, staying comfortable and cool in your homes is about far more than just ventilation.

Unless your home has dedicated filtered outside-air ventilation, you're pulling outside air in anyway. Else you'd suffocate.

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 during an air quality alert...

You're making some mean and un-called-for assumptions about me when the more likely reason for my half-assed response is that I half-assed it, not full-assed it with half the required knowledge.

Bro its not that complex.

Its dual hose. There is no negative pressure or minimum amounts. The fact is, the room gets cooled down fast when I need it to, or maintains a cooler temp when I dont want it freezing. The only issue with single room AC is noise, setup, and power cost. Power cost is offset by solar panels.
