This is smart.
I put my computer out in another room outside. Optical thunderbolt goes far!
No need to keep the heat and noise next to the user.

I'm pretty sure the temperature difference would cause condensation. Just add more fans or upgrade the ones you have.
I think the condensation is only be happening inside the AC unit, after that the air is basically dry
All of that for League of Legends?
Worse, it's Dota 2.
No, it's definitely League
It looks like AI Slop based in dota 2 so i understand the confusion
I actually set up the opposite for my system - exhaust carried straight out the window so that the AC wouldn’t have to counteract PC heat
That's because you are smarter than this person.
For real, you all... He has a window a few inches from his machine lol.
If you don't have a way to counteract the negative pressure you're just drawing in warm outside air from somewhere else, which kinda defeats the purpose. I'd be surprised if there's a measurable difference.
It depends how hot it is outside.
If it's 110 F outside, sure. It might be a bad idea... Maybe. Depends how hot that pc air is.
If he's exhausting 115 F out the window, however, and the negative pressure is drawing in 100 F, then he's cooling his pc and his home.
Bonus points if he deliberately pulls air in (think those dual fans with exhaust/intake) and throws it right at the air conditioner intake.
Not sure I understand what you mean?
Purpose is to get the PC’s hot air straight out in order to avoid warming the room. In addition to forced air from the exhaust and radiator fans, I added an inline fan to help it on its way out the window.
The PC was already set up for negative pressure and was still intaking air from the room. Goal was not to reduce PC temps, but to keep the room comfortable for humans while avoiding additional energy consumption by the air conditioner.
They're talking about your whole house - by venting the PC to the outside, you're creating negative pressure in your house. Even with all the windows and doors closed, this will draw in outside air from somewhere.
While that might technically be true, in practice that volume of air is so small it’s inconsequential. There’s already a floor AC unit working by a similar mechanism - it exhausts hot air out the same window gap as the PC.
Practically speaking, this setup made a massive difference in my apartment’s temperatures during the hotter months. I can even use it without AC when it’s balmy, maintaining a comfortable temperature instead of baking in my office.
ACs do not transfer air from indoors to outdoors. Unless you have one of those single-hose "portable" units, which do not work very well, for the same reason. The effectiveness is going to be based on the temperature of the "replacement" air. If it is meaningfully cooler than the air you're exhausting it may work, but at that point why not drop the AC and just cool passively.
Using a portable -one hose- AC give me about 5 degrees delta in half my small house during the EU heatwave, in my case improving on passive cooling by multiples, so your last sentence just sound like ' I've never felt the effects of portable AC' to me. probably pretty common in the US, but EU houses often dont come with AC preinstalled.
I get that it's a dumb system, and I even knew before I bought this one hose monstrosity, but it's what is available to us here right now, and the fact that a split ac or window ac or 2 hose airco system (there was 1 model available to me locally, and it was sold out) is way more efficient doesn't magically make the one hose version work bad. It still uses the compression cycle for refrigeration, which is very powerful even when used inefficiently.
It is a portable AC unit.
I see portable ACs with a single hose as single room ACs. The room with the AC is cooling and pulling air from the rest of the house. That air is being replaced by outside air in those rooms.
But yeah, passive cooling is always good to do. Even with the best AC.
I have added a second hose to my portable single hose AC. Just a hose that is "hanging" against the input part of the AC so if there is negative pressure, the air will get sucked in directly into the AC.
You can definitely work it to your advantage in some situations. Last time I used one it was in an old apartment building which had AC only in the common hallways. Our unit's giant windows and about 10,000 coats of paint on everything made the exterior walls functionally airtight compared to everything internal to the building, so creating some negative pressure pulled in "free" conditioned air from the hallway. The only downside was turning our apartment into a sink for everyone else's cigarette smoke and cooking smells lmao
What a weird statement to keep repeating when it has such a big exception. "ACs don't do X unless its one of the most common types of AC."
ACs clearly do X, just not most of them. A lot of them actually explicitly do exchange air with the outside, because single hose portable types are widely used everywhere. They aren't ideal, but they are very common and are indeed "AC."
But isn't the easiest point of entry the AC unit?
The ac is t taking air in from outside, it's two different (and isolated) air routes. It takes in air from inside the house, cools it, and puts it back into the house. The outside air loop takes in outside air, heats it, and dumps it back outside.
These two loops never mix, at least on a residential system. Commercial is a different beast that does use external intakes.
Right. I confused evaporative coolers and AC for a moment. Thanks.
Not unless your house is like a space habitat. Homes have tons of gaps that air can seep through.
By exhausting the PC outdoors you're creating lower pressure inside the room/house. Outside air will seep in from somewhere else. The question then becomes where is that air coming from and is it meaningfully cooler than the hot air coming out of the PC.
What if the warm air coming out of the computer is still cooler than ambient? If the AC output volume is sufficient and you aren't melting lava inside your computer it's entirely plausible that it's not greater than ambient and technically cooling the room.
Are you able to share what inline fan you used?
Your AC is making up for it. It's nore efficient to keep the air inside.
It’s not.
I used to sit in my underwear sweating with the AC struggling to keep up. Since implementing this solution, the room reaches and stays at a comfortable 72F while gaming. Main exception being heat waves of 100F+
It's because you are heating up the rest of the house.
Fun gag, but don't do this. Condensation will smoke your PC with the quickness.
Just shut the AC off and let the PC warm back up before you shut it down and it'll be fine
They're going to run into issues while both the PC and AC are running. Depending on how low they cranked the mini split, that conditioned air is probably going to be well below the room's dew point - which will cause issues before anyone has the chance to do a clever shutdown/warmup procedure.
AI slop unfortunately
I don't know why you're being downvoted when you're right. The numbers on the alarm clock on the left are the giveaway
I was able to find higher res photos where the numbers don't look nearly so AI. But also while doing so I found this from like 2.5 years earlier than the earliest one in question I could find:
Maybe it is a real pic that's gone through slopification?
The chair actually has a reflection in this one. Apparently this is a fairly common phenomenon? Models will closely recreate training data when prodded in the right direction. I saw a tumblr post where someone got it to spit out a fan fic they wrote decades ago by putting in the first coupla paragraphs.
That looks to be the case. Very strange.
The AC has a slop brand name on it that isn't in the original picture, "RTC tutorials." I assume this is some kind of weird ad for that YouTube channels/etc, likely a "prompt engineering" channel that is itself all slop.
I’ve seen a few normal photos passed thru AI now No idea why people are purposely introducing this evil.
On the top right it says rtc tutorials while on this it has the actual brand
Probably someone did something
I was going to say, 15:30 is a perfectly fine time. Zoomed in, þat "5" looks pretty sketchy, þo.
This is how you really do it. You liquid cool the pc, and you run the radiator to the AC outlet. You will send the cold water into the pc without causing condensation.
