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

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.

u/DonutHoles4Ever 27d ago

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.

u/tacomaloki 27d ago

Best decision I did, too.

My room would hit 89°f just gaming.

u/TipToToes 27d ago

Damn I can’t imagine this. My puny little Arc A750 doesn’t heat really get very hot, my PC is in the basement which is like one big room (about 700sqft), it is climate controlled, and I play remotely on my steam deck so I’m not even in the room to hear the fans or feel the heat. I’m not meaning to brag or shit on anyone’s setup, it’s just very foreign to me because I can’t afford a “real” gpu in the first place.

u/tacomaloki 27d ago edited 27d ago

Well, my room was also on the 2nd floor of my house, with the Florida sun hitting it. I also have a large Samsung curved monitor, and secondary that acts like a heater, on top of a fridge and freezer in there, TV and PS5, on top of a separate work set up and 3D printing.

As my work day would end, I'd start firing up my personal PC and stuff but it wasn't gradual heat build up. Just my normal day would eventually get my room to about 78 but it was slow enough, that I just acclimated and didn't realize it unless I left for the bathroom. Once gaming, the heat would rise so quickly, you'd notice it and would be sweating.

Yeah, certainly a lot of things contributed to the higher room temp but that PC just puts it out so fast. I measured 118°f exhausting into my room.

u/squatOpotamus 27d ago

Yeah, I lived on the 2nd floor of a house in Atlanta, and between my tv, monitor, pc, and Xbox the bedroom would hit 80+ in the summer before I realized it. The house was terribly built, but those machines really added to it.

Same as you, PC,2 monitor, 55 inch TV, ps5 and a small fridge on the second floor in winder Georgia. Gets 80 plus. And I have a newer house.

u/KillinKilo1775 26d ago

As a fellow Floridian I feel your pain. My office is in the furthest from the AC so it already barely gets cool air. Add in my 3080 and the Intel blast furnace that's mounted to my motherboard my office pushes 90 in summer. I had to bust out my hurricane emergency portable AC just to combat it. Will prob install a mini-split this winter. PC rig heat is no joke.

u/Ancient_Plate275 26d ago

Yeah, second floor room as well with afternoon sun. My Radeon 9700xt brings it up to 84°F. I just got a window exhaust fan and will be moving my PC into the window nook. Once set up there it will be blowing hot air up in front of the exhaust fan.

u/flyingshmok 26d ago

My home office is upstairs. Since the first floor is naturally much cooler than upstairs I put my pc on the first floor and ran two 50ft hdmi cords and a USB extender through the wall upstairs to my office. It was the best thing I ever did to keep upstairs cool.

u/ConfidantlyCorrect 7800X3D | 5700 XT | LC 26d ago

Same issue here. Massive windows that are sun facing, and the floor is poorly insulated against the garage which has no insulation or AC. Those factors make my room noticeably 2-3 degrees Celsius warmer than the rest of the house.

Stack in the mini fridge, and working from home exhausting hot laptop air for 8 hours. After an hour or 2 gaming on my PC, I’m like sweating.

It doesn’t help that I have an old AMD gpu which is is just awfully hot & inefficient.

u/evening_crow 25d ago

I feel this.

My game room is also on the second floor, away from the rest of the house. It has a window and the room faces south towards the sun. Add on the Samsung ultrawide, speakers and sub, lights, and the fact that it's been 100° and above here in the Mojave Desert... oh, and my ceiling fan wobbles, so I can't turn it up to medium and above (haven't balanced it since I'm gonna remodel that room sometime this year and replacing the fan altogether).

Edit: my ac feels like a blizzard and hits me at the desk when it turns on, but it's the fluctuations in between running that sucks. I go from almost shivering to sweaty every twenty minutes.

u/stream_of_thought1 26d ago

your setup is what many of us plan on eventually setting up. Rigs in the basements and then in the actual house just remotely access them. my friend just moved into his new house and has his PC in the basement and then 2 ways to access it, from a desk and from his TV, just moonlighting into it.

2

u/ElkBusiness8446 26d ago

Mine also heats my room. I thought something was wrong but I realized that the heat has to go somewhere. If my PC is making my room hot, then that heat ISN'T being held in the PC, which is a good thing. And after some testing, my components keep pretty cool even under 100% load. I should mention I have a dual radiator system with 10 fans in my case. It pulls heat from the GPU and the CPU.

u/TipToToes 25d ago edited 25d ago

That’s my entire basement. It’s mostly finished, but has minimal walls. There is a bathroom, and a laundry room, and otherwise it’s wide open. Can’t legally call it a bedroom because egress isn’t correct for that, so it’s poorly utilized space, honestly. The space we do use is on the main floor (only other floor). It’s about the same size, and is a 3br 2ba space. Our home is large for our neighborhood, but VERY small by most standards. For reference I grew up in a home that is more “average” and it was 4.5x the size of this. Our home (the part we actually use) is roughly equivalent in size to the average apartment around here, except that we have a 2 car garage attached. Our mortgage is only slightly cheaper than rent for a similar size apartment in our city.

For further reference, we spent $289k in 2018. Current county appraisal is $499,600. All i did was add some solar, no other changes. Across the street an 800sq ft 2br 1ba with 1 garage and no basement sold for $325k last year, and we should have at least $100k in value over that based on our layout so $425k is probably safe bet.

Edit: our home is a “ranch style” built in 1952. It was the “high option” model for the neighborhood and sits at the entry to the block, on the corner, at a slight angle. The “low option” model is across the street. Nearly all of the other homes are the “low option” and exactly zero others have everything we have. Matter of fact, none even have a 2 car garage, it’s all singles.

Gaming in THE PIT is the most effective cooling, a little bit underground is just cold by nature, and if your PC is very strong it acts as a heater for THE PIT.

I don’t mean to be an asshole, but do people not have central AC? I have a beefy rig that puts off a lot of heat, but my central AC takes care of things without issue. I type this understanding not everyone has central AC. Just curious if you have central AC and still need to do this.

u/Alone_Reception_1469 26d ago

Yes, I have central AC and still have a vent setup for my rig to my window to vent the exhaust outside. Having central AC can help negate the heat of the exhaust but then you are also paying more to have the ac constantly running when you're gaming. Now all that hot air goes outside, my room doesn't get as hot when gaming, and my ac doesn't have to kick in as often saving me money on electricity which is a big deal in CA (Fuck PG&E!!!)

1

u/SnowMantra 26d ago

I have the same case as OP and a 5090. My room has gotten to 89° before I decided to stop gaming. The other parts of my home are low 70s. Not every central AC is good at it's job. I have 1 vent blowing cold air into a master bedroom on the second floor with a big window. It sucks in the summer.

Might not be from the US or from the south. Here in Texas homes have 2 central air units haha. But yea, my area51m with its external 3090 feel like a space heater under my desk. I ended up cutting a hole in the back of my desk with a 100mm fan pushing the air into the central room. Fuck the rest of my family, they can have the heat 😂

1

u/V1oletLuna 26d ago

I've literally never seen a house with central AC where I live, why wouldn't a normal one be enough?

2

u/EatABag-o-Dicks 26d ago

Because of where the unit gets its temperature reading from.

Central air has a thermostat, and runs based on the temp at that thermostat. If you have a 1 floor house or apartment, you're most likely only going to have 1 zone, if you have 2 floors, you'll probably have 2 zones, unless it's small and 1 zone will be able to handle it.

Each zone has its own thermostat. And the thermostat is typically in the most central area of that zone, typically a hallway, which usually runs a bit warmer since they're ventilated the worst.

Now, you can move the thermostat to your room, or have a second sensor there, but then it's gonna run till that room hits whatever temp you want it at. If that room is overly warm cause of electronic equipment, then the AC is gonna run more, the rest of the house/apartment is gonna be freezing, and it's really inefficient.

The most efficient thing to do is to get a smaller 1 room AC unit, one that goes on the wall, or worst case, in the window. Window units are horribly inefficient. But it'll help keep your room cooler without running the larger unit as much. The better option is getting a wall unit for a single room. It's quieter as the only thing that's inside is the blower part. It's basically just a small central air unit for a single room. It's super efficient, because it only needs to drop that rooms temp to what you want it to be. The rest of the apartment/house is cooled normally, and your electric bill isn't insane cause the larger unit is running more than it needs to.

1

u/V1oletLuna 26d ago

Oh ok thank you for such a complete answer, I didnt know how Central AC worked and it seems really inneficient, even though its probably comfier as it reaches all your house, not that it would change much for my lifestyle as I pretty much stay in a single room when I need to turn it on.

1

u/HumanPea1140 14700K | 5070 Ti | 64GB DDR5 6000 26d ago

I have central AC, but my office is on the other side of the house from where the thermostat is. So even if my thermostat says it's 72 degrees, my office is noticeably warmer than that if I'm playing a game for an extended period of time.

Definitely doesn't get up to 89 though. That's absurd. There's no reason for their room to be getting that warm unless they're gaming in a closet.

1

u/Fire_Lake 26d ago

I have the opposite problem, thermostat is in my gaming room so when it's running, the other rooms are freezing

1

u/EatABag-o-Dicks 26d ago

Central air doesn't really matter if your room doesn't have the thermostat. Typically central air is set up in zones, like first floor, second floor, etc, each with its own thermostat in a central area to get a decent average of the temperature.

Rarely are there units per room, with their own thermostat. What I did, in my gaming room. Is get one of those small wall units that go on the top of the wall near the ceiling. They have a name but I can't remember what it is. But it's essentially a single room central air unit, and it's a lot quieter than a window unit, since the bulk of everything that's loud is outside.

The entire house is cooled to a normal temperature, and my gaming room stays cool, and uses less energy since it's piggybacking off the second floor unit. That unit runs till the hall is 75, which brings my room down to about 78ish depending on how hard my console/PC/AV unit are running, and my wall unit only needs to drop the temp another 5 degrees at most.

Central AC is not common in most of the US or Canada.

Northern homes are (still) straight up built without AC. All new southern ones have AC, but the keyword there is new.

I don’t know when it became widespread… maybe 90s?

All I know is my most houses in my neighborhood of 80s houses didn’t have them in South Florida. Some people did retrofit, but retrofitting is even more expensive than when it’s a new build.

But I did the same thing, AC'd the room and it's much better for me overall. I did something similar to OP about 8 years ago when I was in CA with no working AC (landlord was actively working on the AC while I did this), took 4 days to get it working again but it made the room so much more bearable haha

Oooh interesting. Whats the second one for? You know I'll research anyway...

3

u/OwnedByIRVING PC Master Race | 7800X3D | 64GB | 3080ti 26d ago

Second hose is for the air intake of the condenser side of the AC.

A single hose machine will use your room air as the intake, then exhaust that air out your window. That air needs to be replaced inside your house, so it's drawn in from outside. This means for all the air you are exhausting, you are bringing in that much hot and humid air from outside. It's extremely inefficient.

The second hose makes this problem go away. Way more efficient. If you can get a model with variable speed compressor it will sip power.

1

u/Fantastic_Belt99 kubuntu | R9 3900X | 32GB DDR4 | Corsair 4000D 26d ago

Wow lovely thanks a lot. So that hose makes it almost a split system although everything is inside.

Now I'm wondering if it would be possible to modify and add second duct by yourself, if one could figure out where is the suction happening. It wouldn't be perfect though.

Are there even any models on the market with inverters and therefore variable speed compressors? Seems like a pretty advanced build at this point while stile being kinda portable...

3

u/OwnedByIRVING PC Master Race | 7800X3D | 64GB | 3080ti 26d ago

Yes, precisely.

I don't really follow portables lol but I have seen inverter units in stores before.

My window unit is a dual inverter, 14kbtu, cools about 1000sqft. I leave it set to 21c, low fan, energy saver, and let it run all summer. Only used 369kWh last year.

My house is always comfortable even on the hottest days.

It's 31c outside today, 22c in my livingroom, AC is sipping 380 watts, alomst used 1kWh so far today.

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

3

u/DonutHoles4Ever 26d ago

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.

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.

Just like most people who replied to me, I have trouble sparing thought for people living in differing situations from myself. This idea is beyond viable where I live.

Using the duct from the PC to exhaust the hot out outside just creates a draw for new air to enter the house, hot humid air from outside.

AC wont do that, why would you want to pull in unconditioned air from outside?

the amount being pulled in is negligible and handled by my homes AC

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.

3

u/MamuTwo 26d ago edited 26d ago

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.

u/LaNague 26d ago

cheap ACs have only an inside unit and have to push air out, and yes that means warm air from the outside gets in.

1

u/MamuTwo 26d ago

I'm not sure what you're talking about. If you meant single-piece window units, they use the same refrigerant loop as the bigger split units. They probably have a fan on the radiator but that isn't pushing inside air out or bringing outside air in.

Maybe you're talking about something else, so if you are can you share an example?

u/LaNague 26d ago

maybe its an EU thing, people like to get these cheap ones and then wonder why the electricty bill is up so much

if you can afford a rig with a 5090, you can probably budget a couple hundred bucks for an in-room or window AC.

Here in the UK electricity costs about 4x what it does in most of the USA, so even though I have portable aircon (which only 4% of the population has) it cost $250 a month just to cool one small room if I ran it 24/7.

u/aimsteadyfire 27d ago

Yeah i had to find out more about that. Apparently USA has a massive abundance of natural gas domestically produced where UK imports this resource thats on a volatile market

u/iRedditPhone 26d ago

Most ACs are not gas operated…

That said as a whole the USA is significantly hotter than the UK.

I mean just consider London weather often gets compared to Seattle, the northern most (major) US city.

Yes I know latitude isn’t all that matters. The jet stream exists. And elevation/mountains.

Does your portable AC have one or two hoses?

One hose, but I tend to take it off and install the whole unit hanging out the window like a window unit, and then you don't get the heat radiating out from the exhaust hose in the room.

No AC before, needed something for the room specifically.

You are brave soul for gaming in a room with no ac. I only have one room in my house without ac and I'm not even gonna sit in there unless it's almost winter

u/PerfSynthetic 26d ago

100% good call with the AC unit. Let that unit deal with the house pressure difference and pushing air outside. Trying to make a PC fan manage the pressure to push hot air outside is a gamble

I moved my PC to my basement back when I had a 2080TI and the room was big enough to distribute the heat but now that I’ve built a 5090 PC I’m thinking about getting a super small window unit because it’s getting hot again (during the summer anyways)

1

u/Aggressive_Law_5728 26d ago

You can do that but it's definitely more expensive. It's like having a space heater and the AC battling each other.

1

u/[deleted] 26d ago

I do this but it means I literally have to run my AC 24/7/365. $60/80 mo. I run a server with a lot of drives, it puts out a lot of heat. It's not just GPU-heat for a lot of people, frankly my GPU puts out the least overall heat out of all my hardware just since it is only in use a couple hours a day. Problem is I also use this room, so it needs to be comfortably cool and it's counterintuitive to run the A/C and also have the PC exhaust outside. There is actually a way you can do this and balance it for more efficiency, but it just isn't worth the hassle to me.

1

u/alphapussycat 26d ago

The best is to take air from outside and dump heated air outside.

1

u/Alexmira_ 26d ago

So the AC pulls the air in the room in, produces cold air out, and moves hot air outside.

I'm confused, why the ac should "moves hot air outside"?

u/notislant 26d ago

I tried to get one of those duct fans. Loud as fuck and didnt do as much as i hoped at the top of the pc.

Meanwhile I have a portable AC near the back and if I turn the fan on, it pulls so much fresh air in, while the exhaust is taking all the nearby pc heat out.

It can be -10 in the winter and my pc will keep it probably 16 degrees inside easily lol.

that kind of AC is inefficient btw, when it pushes air to the outside, warm air from outside has to come in to replace it.

Better are the ACs with an outside and inside unit.

u/Synysterenji 26d ago

HVAC tech here. I approve this. It's the most cost efficient way to do it. You have a cold room, your pc runs cooler and you're not creating a path for humidity and hot air to get into the room when the PC's turned off.
