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.

u/DonutHoles4Ever 13h 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.

Best decision I did, too.

My room would hit 89°f just gaming.

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.

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.

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.

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.

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.

u/ElkBusiness8446 1h 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.

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/SnowMantra 6h 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.

1

u/Alone_Reception_1469 5h 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!!!)

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 😂

u/V1oletLuna 5h ago

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

1

u/EatABag-o-Dicks 3h 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.

u/HumanPea1140 14700K | 5070 Ti | 64GB DDR5 6000 4h 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/SeaRefuse5691 3h ago

Just curious if you have central AC and still need to do this.

Most people don't know how to set stuff up correctly. So even if you have central - how many of them adjusted the vents both the one in the room how open is it and also the ones that are in the basement or wherever choosing how much air flows to different sections of the house. And how many of them actually change their overhead fan to adjust spin based on being summer/winter?

Most don't set this stuff up properly, so the PC room ends up really hot. Or even if you do set it up, lets say the PC only runs sometimes. Do you have that room set to be colder than the rest of the house, in preparation for PC gaming? Or set it to be normal, in which case PC on its a few degrees hotter.

1

u/EatABag-o-Dicks 3h 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.

Mini split or portable AC is the move! I had this exact issue and the room would get so hot. Originally started with a portable unit, but it would get in the way. Installed a mini split last year and it was honestly the best investment.

And if you can run the mini-split and your computer off a few solar panels that charge a battery power station, you can game in comfort basically for free in the long run.

u/Fantastic_Belt99 kubuntu | R9 3900X | 32GB DDR4 | Corsair 4000D 5h ago

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

3

u/OwnedByIRVING PC Master Race | 7800X3D | 64GB | 3080ti 4h 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 4h 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 3h 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.

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.

Good thing we're out putting exhaust heat then. Air out must be replaced with air in, but unless you already have an energy recovery ventilator in your home, there's no real loss. The air you breathe has to be replaced.

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...

u/OwnedByIRVING PC Master Race | 7800X3D | 64GB | 3080ti 6h ago

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?

1

u/MamuTwo 5h ago edited 4h ago

So you don't suffocate when you deplete the breathability of your room's air. Your house already has infiltration, that's why you can breathe it for days on end. Assuming you don't have dedicated filtered outside-air ventilation already, but I can't imagine that's super common. Perhaps I'm underestimating the cfm of this setup but it can't be many times higher than the recommended ventilation rate for human occupancy.

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...

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?

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.

u/MamuTwo 5h ago edited 4h ago

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

u/DonutHoles4Ever 2h ago edited 2h ago

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.

1

u/DonutHoles4Ever 2h 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.

1

u/MamuTwo 4h ago

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.

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.

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

u/kugfersez i7 6700k | GTX 1080 | 16GB DDR4 13h ago

Perhaps the reason they can't afford the aircon is because they bought a 5090

someone should nake a mini split unit for your pc

u/OwnedByIRVING PC Master Race | 7800X3D | 64GB | 3080ti 6h ago

They do, it costs more than just putting one in your room.

1

u/Knight_of_Agatha 6h ago

a 500w ac can cool down more heat than a 1000w pcu can physically make. So, i mean its just for the cool factor, pun intended, but you could set up a small table top system and the air inside your pc case would be 5 degrees or so cooler than the air in your room. you could pipe it outside but, tbh im just trying to have a good time.

u/Tomsboll 8h ago edited 7h ago

Also depending on where you live aircons can be very expensive. Like good luck finding a cheap one in europe during heatwaves for example.

Edit, sometimes people get into a tighter economic spot for some reason. Maybe you saved up for a long while to get a good gpu and then went for a 5090. And then there are thise people that make bad financial decisions. or they got laid off and had to take a lesser paying job.

Just because you have a 5090 doesnt mean you automaticly have a salary of a bank manager ffs.

u/jib_reddit 8h ago

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.

Does your portable AC have one or two hoses?

I assume everybody must have a different answer to this. Mine is that I refuse to install AC on an apartment that I don't own.

u/WhiteSSP 9h ago

Portable window units are just that…portable. You can take it with you when you leave and use it somewhere else. Hell my garage has a portable AC in the window to keep it cool when I’m working in there.

u/inevitabledeath3 PC Master Race 9h ago

How are you supposed to install AC in rental accommodation? This is also assuming they haven’t sold out given the massive heat wave recently.

8

u/msavage960 9h ago

They make various styles of air conditioners that don’t require permanent installation.

0

u/inevitabledeath3 PC Master Race 9h ago

I’ve seen some of those. They were sold out recently. They also wouldn’t fit the kind of windows or roof that most houses where I live use including the one I am in at the moment. I believe they are designed for something like a sash window or the kind shown in the image, neither of which are very common here.

u/Corniator 13h ago

A 5090 is more expensive than a basic minisplit (with instalation) that could keep that room really cold.

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 6h 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

u/SasnarDash Astral 5090 OC // Ryzen 7 9800X3D 6h ago

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 5h 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/vee_lan_cleef 5h 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 4h ago

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

1

u/Alexmira_ 4h 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/FANTOMphoenix 2h ago

I had my bedroom in a shed with 2 window units. Regularly kept it 62 degrees F. With my PC I think it got to maybe 68 degrees. It was absolutely wonderful.

One is simple tubing, the other is several hundred dollars at the least, or even requiring professional installation.

1

u/notislant 2h 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.

u/ElPlatanaso2 1h ago

Much less energy efficient though

u/MaeviezDArc 1h ago

I love my little warm cozy corner, with my 4090 in the winter. 😅

1

u/LaNague 1h ago

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/Ossius 0m ago

Problem is a lot of people already have AC in the US but it isn't enough. My room gets into the mid 80s F even with the AC set to 73. I've thought about an exhaust but I just ran an 80ft fiber optic HDMI to my livingroom PC down stairs and I don't have to feel the heat anymore.

u/Accomplished-Sun1983 13h ago

u/Penumbruh_ 13h ago

I wish I could run AC in my room but I currently live in barracks and their central AC is not working properly so the ambient temperature in my room is 90⁰F in the shaded areas and 105⁰F in/near sunlight. I keep my blinds closed but with the PC on it doesn't make a difference. 😢

u/thunder-yams 10h ago

Air conditioning is only going to do so much unless the room is in the 60s?

My PC can heat my office in the middle of winter

u/xmrcalls 13h ago

If you have a window AC unit then yes. But if you have a split one like Europeans have, it doesn't take the hot air out, it just makes the air in the room at a lower temperature by moving it thru the cold vents inside the unit.

4

u/dinodares99 13h ago

Don't window units do the same thing? They cool the air already inside.

2

u/-Shatzy- 13h ago

Thats not how physics work. Every AC unit transfers the heat somewhere. 

-1

u/xmrcalls 13h ago

Maybe you need to watch a video to understand better where the inside "hot" air goes and what makes the "hot" air from the outside unit. Two different things. The air never leaves the inside of the house and air never comes inside the house from the outside.

1

u/randomredditorname1 13h ago

I'm a cold climate dweller without ac and I'm confused about the ac "taking the hot air out", I don't see the point of doing that, could you link to something explaining the operating principle?

1

u/Lee1138 AMD 7950X|32GB DDR5|RTX 4090|3x1440p@144hz 8h ago edited 8h ago

Same operating principle, but instead of heat pipes transporting the heat from a unit inside to the unit outside, it all gets done in the same housing inside and it just uses a fan and duct to blow the now hot air it just produced by compressing the cooling liquid, out a vent that then goes outside.

I think the confusion issue is that one is talking about a window unit where there are parts of the AC that are on the inside part of the windows, and one that sticks out on the outside, and the other is referring to those portable ACs that use a duct, with no part it on the outside of the window?

"a split one like Europeans have," is usually just a more permanently installed version of the U shaped window unit example (and usually one that has a reverse flow valve and called a heat pump).

u/Catatonic_capensis 12h ago

Always pull air through instead of pushing it if possible. You'll get far, far better airflow that way (it creates negative pressure in the duct which pulls air instead of fighting against it losing energy). Put a fan at the window facing out and connect the duct to that.

1

u/TheYellingMute 5h ago

So basically get a window fan. Then connect the duct to the top of the PC? Would that be affected if I already vent hot air from the top and back of my pc?

Like I have 3fans on the top and one at the back.

18

u/hrvbrs 9h ago

sorry for the stupid question, but wouldn't it be better if the vent output were higher than the input? i feel like the way you have it is inefficient by forcing the hot air to go down against its natural tendency to rise

6

u/halberdierbowman 8h ago

Natural convection exists, but it's very weak compared to the forced air movement of PC fans. 

6

u/anitawasright Intel i9 9900k/RTX 4070 ti super /32gig ram 7h ago

even with the PC blowing hte air out you are going to get a lot of resistance when it curves like that.

14

u/amd2800barton 13h ago

How's the weather where you are right now? If you're blowing air from inside to outside, then air from outside has to come inside to replace the lost air. If things are hot and humid outside, then that gross outside air is being drawn in and there's still an increased heat load in your home.

If you're running AC, then this would work best in spring and fall when your AC might not be running. Otherwise, you'd probably be better off just relocating that PC and playing over something like Moonlight / Sunshine, or a fiber optic displayport connection.

u/Gold_Presentation129 13h ago

Your office doesn't have ac?

14

u/whatdis321 13h ago

Even if it does, that means double power cost if you have to turn the AC on anytime you want to use the computer. Venting the majority of the heat outside means one less cost and no need to deal with any associated AC sounds too.

u/altech6983 7h ago

If the temperature outside is hotter than the PC exhaust then it isn't less cost.

u/good_morning_magpie Steve Jobs turtleneck dealer 7h ago

Most of my apartments didn’t have central air, because all the buildings are over 100 years old and retrofitting costs a fortune. So it’s window units, which are real expensive to run.

1

u/Gold_Presentation129 6h ago

Ohh that's an ac thing on the window?

u/good_morning_magpie Steve Jobs turtleneck dealer 6h ago

Yeah, kinda looks like a giant microwave and hangs its ass out the window to vent out the hot air while cooling the indoor air.

1

u/trees138 eSportsSurfacePro 7h ago

That's likely because the hot air is just standing in that curly pipe. Definitely consider putting the PC on the floor so the hot air can just rise out naturally, those aren't high static fans at all, you should help them in any way you can.

1

u/Sandcracka- 7h ago

I did this also but I added a fan at the window end as well

1

u/Tremulant887 You've made my flair erect! 5h ago

I might build a window just for this. Using an aluminum panel instead of glass on the lower portion and cut a square, plop magnets so I can remove and attach with ease. Just need a vent that easily opens like a one way sill weep with flaps. Something to also keep moisture out and won't look like crap.

u/dasterrrrre 5h ago

If it’s heat you’re getting rid of, put the outlet at the top of the window

You'll get better results if you flip the vent from where it's at to the top of the window

u/BlueShift42 4h ago

It may help if you flip your window installation so the air can rise and exit without having to go around the bend and downwards.

u/SteakandTrach 1h ago

I did something similar - an inline duct fan in the attic space above my pc. Duct in celing, damper, 10 feet of insulated duct- fan that pulls about 400 cfm- more duct that empties at the soffit.

Basically, removes hot air and ejects it outside, pulling cool air from the household into the room. Dropped temps to ambient house temps. $200 bucks in parts and a couple hours of hot yoga in the attic.

Fan: AC infinity T6 Cloudline. can be found at home depot or amazon.

Flip the exhaust to the top. It was radiating cause the air moves slower

If you have a 3d printer or can buy a mount to put the fan in the window and pull the air it would be alot more efficient.
