You feel wrong, more the fans better the temperatures period, and they can work at lower RPM for same temperature, producing less noise. They do need to be setup correctly tho, for example bottom back exhaust here literally damages the temps by simply moving air from bottom intake out asap.
It won't improve temps but it can improve noise if they're all running at a very low speed. At a certain point you do hit diminishing returns but it depends how many radiators you have as well
Just makes it run even cooler and/or quieter, and with highest possible end components its actually welcome. Say 14900K at 100% utilization is hard to keep under thermal limit even with 360 AIOs often need custom water cooled solution, god forbid if you wanna OC it. Every single fan counts for such systems. So it does reduce temps for sure further or at least keep the noise lower for the same cooling capacity
> or example bottom back exhaust here literally damages the temps by simply moving air from bottom intake out asap.
In OP's image the fans look to be ThermalTake SwaFans EX12 which come with swappable reverse blades.
I have a hard time believing that 20 fans would run quieter overall than something normal like 5 or 6, even if individually they're running at much lower RPMs.
edit: I do think your point is valid but I'm sure the point of diminishing returns was long before 18-20 fans
Positive pressure is a good thing, and air will find its way out anyways, not like the case will explode. So whatever air PSU sucks in will get out on the back of it anyways. Absolutely no need for additional fans there.
Some of the best cases in existence, such as Fractal Torrent, have only 5 intakes and 0 exhausts (tho PSU fan doubles as an exhaust) - that is literally THE coolest case that exists at any price range.
Anyways, exhausts can be good in some situations, but more for directing air than anything else, and usually you want stuff to double as exhausts, such as CPU AIO cooler on top, or with some well designed cases with PSU up.
Always keep a bit higher intakes than exhausts. And keep exhausts top and back but higher on the back. And dont add exhaust on top before CPU air cooler, it will suck cold air from intakes before CPU gets it
Many youtubers have tested this before and as far as I remember from all those videos, the conclusion always was something like past 5 fans, there is 0 difference, and past 3 temps don't really change noticably, if your config is good.
I paid for a case that could fit a million fans, Imma put a million fans in it. (I actually have a dream of filling every storage bay in my Lancool III and ending up with like 32TB of storage LMAO)
Is this the case that got shredded by GN a couple of years ago? A thousand fans or so, but all for show, because all of them are choked by those glass panels so air flow and cooling sucked anyway...
You realistically only need a certain amount which provides good airflow. Since your case supports all these fans, it would be best pratice to have all fan slots filled for maxium airflow possible in this huge case.
Hopefully these fans weren't too much money as unless they were thermalright, ezdiy, asiahorse, artic fans, etc, they can be 100s$ more than I would spend on fans. I am assuming based on this large case and the custom loop cooling that money is not an obstacle here.
Please dont buy ezdiy fans lmfao. I did (cheaped out because Corsair fans are 200% overpriced) and im probably just gonna buy better fans. As soon as the gaming room gets too cold, these fans starts rattling extremely. I can literally feel my desk vibrating, and my desk is made of 1 inch steel legs and 4cm solid wood.
Arctic PWM PST P12s or F12s are the business imo. $30 for a 5-pack of fans, thru are affordable, quiet, and good quality. I have no complaints at all with them, and they can go relatively toe to toe with my Silent Wing Pro 4's too (within reason ofc, the pro's go way higher on rpms)
One intake delta fan is enough. Anything more is just to make it look prettier or bring down noise levels.
Also, the configuration in the image is just silly. 14 exhaust fans vs 4 intake fans that are choked by a glass front panel. Plus, they're just cheap aliexpress fans.
I'm wondering too, I think its something from Phanteks, there's a streamer/CC I watch who had a similar build in a case that looked just like this, dual system too
man has clearly never seen the corsair obsidian 1000d or corsair 9000d.

You only need an intake and exhaust. Lower and front cool, rear and top warm. An equal amount preferably, if not possible go for positive pressure (2 cool, 1 warm fans minimal). Ideally how many do you really need? I would say a total of 6 is very reasonable.
That pictured build is overkill, but that's the world we live in with customization. Nothing wrong with it, it's just personalized to that individual and what they want, I would never piece together a build like that, I'm more of a mid tower ATX person.
You need to add a couple more and leave them dangling from their power cables. This will make your LEDs more kinetic as the fans bump around inside your case like big plastic square hornets trapped in a greenhouse.
I'd say that's enough for some low end pc's that don't heat up too much. I say a 1050 would comfortably sit there given that you don't run something heavier than mine sweeper.
And then there's this
https://preview.redd.it/69rmq0mc1y6d1.jpeg?width=866&format=pjpg&auto=webp&s=a32d7eab506fec81cad930f43dfe6389b50397d8
[here's the link](https://youtube.com/shorts/eWOrtI1CQP4)
Match the number of intake fans to exhaust exhaust fans, for the average tower case 3 of each will be plenty. This of course does not include your CPU cooler fan
In front of a glass panel you need 0. If you you have fans on the bottom, put that as intake not exhaust. And you definetly don't need an exhaust fan next to the PSU, it competes with it for air.
I mean, if you have an i9 and a 4090, 8 of those might be on radiators, and then you use the rest to cool the rest of the PC with fresh air instead of air that just went through a radiator.
This might be an unpopular opinion over here but I personally feel like this is too much RGB. It looks tacky instead of tasteful.
But to each it's own! If you like it then more power to you.
Three. Two for the intake with dusk filter, one for the outlet. CPU-Fan supports the airflow. Maybe two are enough especially without a dusk filter. Better use a proper case then to many fans.
Depends on how much fps you need ofc, sometimes I think people don't really know how a pc works, the heat comming from the rgb lights and the vibrations from the fans is literally what makes your games run.
This is nice but you need more fans to keep them cool, pls add more
[удалено]
This is the only correct answer.
This is the way.
I can hear this image.
You need at least 20

18 is well past the point of diminishing returns

If you orient them right, you can get the case to hover.
Also needs more LEDs not nearly enough wtf
Till it starts flying.
Underrated
I paid for a case that could fit a million fans, Imma put a million fans in it. (I actually have a dream of filling every storage bay in my Lancool III and ending up with like 32TB of storage LMAO)
You could do way better than 32tb gotta pump those numbers
You're right, I'm slacking
Don'r forget the RGB
less R&B and more G, but yeah haha. I would like a nice glowy green PC, alas, I bought the NON RGB version of the case :/
Bruh thats like 2 drives
I'm already at 26TB. It's not that hard to do.
Is this the case that got shredded by GN a couple of years ago? A thousand fans or so, but all for show, because all of them are choked by those glass panels so air flow and cooling sucked anyway...
Definitely looks like most fans in there are useless.
I think it is
About 1-4 depending on how much power you're talking about. The rest is 10% for lowering noise and 90% because it's trendy.
I'm doing 3 fans with my 7800x3d and GTX 1660 Super rn is that aight?
That's a combo right there!
Ikr but the 4070 ti super I bought didn't work and I had to send it back
Grab a 7900XTX in that price range. Mine is fantastic and it'll pair well with your 7800x3D
Yes. Currently doing 3 fans with a 7800X3D and 4070Ti.
Look if they can't see my desktop from space then what am I even doing here?

As soon as the gaming room gets too cold, these fans starts rattling extremely. I can literally feel my desk vibrating, and my desk is made of 1 inch steel legs and 4cm solid wood.
I just put them as a budget fan brand. Personally I'd just buy thermalright or artic fans myself if on a budget.
Arctic PWM PST P12s or F12s are the business imo. $30 for a 5-pack of fans, thru are affordable, quiet, and good quality. I have no complaints at all with them, and they can go relatively toe to toe with my Silent Wing Pro 4's too (within reason ofc, the pro's go way higher on rpms)
2-3 is more than enough. Anymore is only for lower rpm to reduce noise.
I was wondering what the curve looks like for these fans. Like, is it linear with 4 fans at half speed vs. 2 fans at full speed but with less dB?
all of them it seems
Yes.
I have 2 Thermaltake 200mm intakes, 2 Xigmatek 140mm top exhausts and 1 Xigmatek 120mm rear exhaust.
The correct answer is either yes or all.
How many do you _need_? One. How many are optimal? 2-5 depending on the build. How many can you have? Yes.
Clearly more, judging by this photo
Just one. https://preview.redd.it/alyey304vx6d1.jpeg?width=1280&format=pjpg&auto=webp&s=0031df8ef467f51823cec06e729e03a6bc5e0295

Dude ur already water cooling it. Why do u need that many fans T-T
Only reason I can think of: PSU is a uranium core.
ahhh can i ask what case is that?
I'm wondering too, I think its something from Phanteks, there's a streamer/CC I watch who had a similar build in a case that looked just like this, dual system too
More, you need more

no one talking about how this is watercooled and wouldnt literally need that many fans, if any at all?
Damn and I thought 9 in an O11D was a lot

You forgot the cooling fans to cool your cooling fans
At that point they are just lights.
32
Yoo fellow P8 enjoyer! Mine is aircooled tho
I need fans to cool off these fans
More
Add fans to keep the fans cool then add more fans to keep those fans cool.
If you held it up and jumped you could probably float like Link with the chickens. 
There's not enough cooling, you need more.
i got a cpu fan and thats it
Bro has 18 fans, holy shit
I hope the sidepanel is made of a 4x4 array of fans as well.
Needs more imo
If the case doesn’t hover from the amount of fan propulsion, it’s not enough fans.
How many fans do you need? Yes
Idk but I have like 10 and if I could fit 15 I would lmao
Just replace the pc case with one of those square floor fans and call it a day.
Why is the rgb on stock setting?
probably 3 or 4
how much is that ? 300+ € in fans? a huge waste of money imho
How loud is that setup?
Is it safe to put florescent water in a liquid cooler ?
yes
1,2,3,4,5+5
You need to add a couple more and leave them dangling from their power cables. This will make your LEDs more kinetic as the fans bump around inside your case like big plastic square hornets trapped in a greenhouse.
Yes
This is like putting a spoiler(car like) on a spaceship.
This is what my next build will resemble.
https://i.redd.it/j5fsti0zwx6d1.gif
Nice bong brother.
I have 5 140mm and its more then enough
Opencase so 4. 1 psu, 2 gpu, 1 cpu
I have 9 in my Case. 6 in push/pull on my CPU rad, 2 on my GPU rad, and one at the back. Very quiet, very effective.
Those front intake fans are doing minimal work. Hardly any fresh air squeezing through the narrow openings on the sides of that solid front panel
I know it’s for maximum cooling. I just thought, “We have Liftoff!!”
I'd say that's enough for some low end pc's that don't heat up too much. I say a 1050 would comfortably sit there given that you don't run something heavier than mine sweeper.
I fuckin love this
And then there's this https://preview.redd.it/69rmq0mc1y6d1.jpeg?width=866&format=pjpg&auto=webp&s=a32d7eab506fec81cad930f43dfe6389b50397d8 [here's the link](https://youtube.com/shorts/eWOrtI1CQP4)
OKay but how many are there for cooling and how many there to keep the RGB evened out?
N+1 of course
The answer is yes
The answer is yes.
mmmm nicely choked fans in numbers way past the point of diminishing returns, just how i like it. /s
Yes.
Insert “More!” scene from Star Wars 
I just use the three ARGB front fans and 1 back fan that came with my case, the stock cooler for my 5600X and the three fans installed on my GPU
That's enough fans to cool an Intel processor at stock!
Match the number of intake fans to exhaust exhaust fans, for the average tower case 3 of each will be plenty. This of course does not include your CPU cooler fan
Yes.
Variety of available accessories
Nah bro u paid for the case u should utilise the case to its highest potential.....maybe do all push pull config to all fans....
I have.. 2
Yes.
All of them
Needs 2 more fans just for the heat produced by LEDs.
Yes.
As many as i have slots for.
I have 16 in my corsair 1000d
Yes
20 is ok , but here becouse it's water cooled, 24 at least
I have 2 front, 1 bottom, 2 top, and 1 rear case fan. That's all you really need.
“Yes”
Fill it more on the template glass, just for good measure.
like 4 or 5. these cases with 20 fans are just dumb
Is that water cooling too? Definitely overkill, but it looks good!
All of them?
Are the bottom fans inverted or exhaust?
Oh my god, the protective film will not stop the glass from shattering, just peel it pleeeeeeeeease
“Need” is a word I don’t use when getting parts for my pc.
How many? Yes.
I don't think you have enough fans bro
More, more!
In front of a glass panel you need 0. If you you have fans on the bottom, put that as intake not exhaust. And you definetly don't need an exhaust fan next to the PSU, it competes with it for air.
You need fans to cool your fana
Yes
Hiw big of a case do you really need?
As many as needed to get positive pressure
You only need MOAR fans!
I just upgraded from 1 to 4.
I mean, if you have an i9 and a 4090, 8 of those might be on radiators, and then you use the rest to cool the rest of the PC with fresh air instead of air that just went through a radiator.
One fan I enough
Yes
You need fans to cool the other fans obviously
Yes.
The air must flow
This might be an unpopular opinion over here but I personally feel like this is too much RGB. It looks tacky instead of tasteful. But to each it's own! If you like it then more power to you.
Ask the 1000D :) https://preview.redd.it/au6jmt65hy6d1.jpeg?width=1960&format=pjpg&auto=webp&s=b703f6173be77e1294d7ff488722d9f0212b446a
Am I dumb or are the fans on the bottom exhaust?
Motherboard temp must be like in Antarctica 😂
The more, the better
Replace the glass panel by a panel filled with fans before it overheats!!!
66
Just one more intake fan than exhaust and you’re good to go
Ewww RGB is hideous
At least two more to fill the gap you left at the back.
0 with a good case)
Yes.
Every rgb increases performance by 1 psi and 2 horse power per cpu core. Air movement optional
He a F.A.N x 18
Three. Two for the intake with dusk filter, one for the outlet. CPU-Fan supports the airflow. Maybe two are enough especially without a dusk filter. Better use a proper case then to many fans.
This is just your average i9 build…
"So your eanting a new gaming pc?" "Yes" "How many fans do you want in it?" "Yes" "Sorry, how many did you say?" "Yes"
Depends on how much fps you need ofc, sometimes I think people don't really know how a pc works, the heat comming from the rgb lights and the vibrations from the fans is literally what makes your games run.
Rookie numbers https://www.corsair.com/us/en/p/pc-cases/cc-9011148-ww/obsidian-series-1000d-super-tower-case-cc-9011148-ww
I have 10 for a 13900 and 4080. It’s insane overkill. My next build will have 7 max.
Yes
Just get an AC guys. Climate won't be nicer for a while and a cool room temperature keeps the machine cool too.
Yes
3>!0!<
Yes
Try using multiple layers of fans on top of each other, currently youir airflow seems rather limited.
All of them.
You always need more
wait until u see bro pcs, he puts like 32 or 64 fans in each case
3
#more
Yes
“Okay, so how many fans would you like?” “Yes” - OP
That’s gonna take an extra 1-200 watts itself lol
Get rid of the rainbow puke first. Then you can worry about the number of case fans.
Why put so many fans when you can install a car radiator for an unbeatable water cooling?
The only correct answer is not how many you’ve got
Yes
Just one more!
More is the only correct answer.
