Why are we discussing 2009 again ?

>>105744362 (OP)
well they are right. what's the point of removing the fresh air out of that upper right blue arrow if your top blue fan is exhausting it right in front of the CPU cooler.

>>105744362 (OP)
in what direction are the fans in the cpu?
or you are trying to say it doesnt matter?

>>105744545
the gpu fans move the air from top to bottom. you're welcome, retard

>>105744557
>cpu=/=gpu
...

>>105744566
think twice why you got that answer

This is the default config of this fan the only difference is that the fan config is up to your AIO at the top if you want that orientation.

>>105744362 (OP)
The top right fan makes no sense to me, as it will be recirculating the hot air that the top left fan exhausted.

>>105744574

I'll try this for the lulz with my watercooled setup the next time I have to open the system.
Right now I'm sitting at 38°C-ish at 10% CPU util at 30°C ambient (no AC here).

>>105744362 (OP)
unfortunately, the common design of the major components of a PC makes virtually every cooling setup a shitshow. The most performant is full water-cooling, but it's expensive and time consuming and has a bad failure mode.

>>105744594
It's the top left fan that doesn't make sense, it should be set to intake as well.

At least post the video

>well, with this particular case
>well, with these particular fans
>well, with this particular fan speed
Cool, it's irrelevant to 90% of people.

The real best configuration is front intake fans only. No exhaust fans at all. source: me

>>105745460
Nah. Hot air naturally goes up. Fighting the cooler's hot hair with a top fain intaking right on top of it makes little sense to me.

Based on these values, should I return the card or keep it?

>>105746170
Wrong thread.

>>105746104
Convection has practically no effect at all in a computer case. If it did, you wouldn't need fans.

>>105746207
You should watch this video >>105745884
Two intake on top harms the CPU significantly.

>>105744362 (OP)
I dont have that specific case but i bought my rig when that image starting making the rounds on /pcbg/ and set my fans like that

>>105744765
Probably. You could try it without the top fan at all and see what your temps are. It really depends on the quality of heat sinks you have on your board, drives, and processor. If you have a long video card, your pic will be your best bet.

>>105746104
>>105746207
The goal should be removing the hot air from the case, not mixing it.

>>105744594
its either that or it takes the air from the top front fan straight out and cools nothing.

>>105744362 (OP)
dumb, top fans should both point out

>>105744362 (OP)
Even their recommended setup is retarded.

>>105746417
better to recirc air on that one fan than place a hungry mouth right next to the cpu

>>105748032
It would likely be best with no fan there.

However, it may be like that to help prevent hot air from the video card from being pulled up into the top of the case.

I reversed my top rear fan and my PSU. I now have 6 intakes and 3 exhausts, up from 7 intakes, 1 exhaust, and 1 isolated. Did my temps get better?

>>105748048
But noctua would lose a sale

>>105744362 (OP)
does this thing have a psu shroud but no fan position under the video card?

>>105748048
>>105748070
Yes, I'm genuinely curious if they tried blanking the top front fan position.
It also makes the most sense to me.

I just took off the case an put it horizontally on the floor, that's where the coldest air is and hot air just rises up from all components, on top of the whole access to air thing. literally don't give a fuck

The fans are diminishing returns the stock flux fans are fine and they really want you to use a AIO for the top mount anyways. Why would I pay that much for a case and not use a AIO?

>>105748108
Yeah it has no bottom fans.
You put the PSU upside-down so it intakes from the same place the GPU intakes.
Not ideal but make it slightly more compact I guess.

The mesh version has a side fan mount so you can theoretically add 2 extra intake fans for the GPU and PSU.
HOWEVER unless your video cars is very narrow it doesn't even fit.

It's not a terrible case for airflow, but it's not great either.

>>105744904
Debunked and obsolete. Get with the times, gramps.

>>105748032
What you do is have both top as intake in this case.

>>105748032
Every single one of these completely ignores the fan on the front of the cooler
Do you think that the top exhaust will somehow pull so much of a vacuum that the CPU cooler's fan will draw in no air?

>>105748214
It won't remove all air but it will reduce the amount of air going through the CPU cooler.
Even the mesh side is bad for CPU cooling.
The clear side panel option is better because is stops the front intake air from escaping.

I still bought the mesh for looks but wish they had a solid black side panel or perhaps one with some wood details to match the front.

>>105748214
Do you think that reducing the inlet pressure of a high static pressure fan won't affect its performance?

The top fan positions are means for a radiator.
For air cooled systems you're not really meant to use them.

>>105748271
>>105748270
I think if your thermals are that dependent on absolutely perfect airflow you're wrong anyway desu~
t. has no top vents and uses a 280mm AIO as my intake with a single 120mm rear exhaust

>>105745884
Yeah this is the only vid I've seen on this and it shows Noctua being right

I'd like more tests

>>105748296
They don't depend on absolutely perfect airflow, but doing stupid shit will give worse results than orienting your fans properly.

i like my case and it gets decent reviews in the default config with front and bottom intake
the wood also matches my fake wood desk and lamp

>>105748214
>the CPU cooler's fan will draw in no air?

No its just a drawing of where some air goes. It depends on the rpm of the fans. On the top front intake fan, the ceiling fan is going to catch most of that before it gets to the cpu because it's so far forward of the cpu fan. But the 2nd front fan is only going to lose some airflow to the top fan. Regardless, what the fuck does the first ceiling fan do? Cools your power cable? No it just takes air that was never heated out of the case. And we want the air that was never heated to go in the cpu

>>105744417
i bet that badboy sinks a whole 35w

>>105748296
>I think if your thermals are that dependent on absolutely perfect airflow you're wrong anyway desu~

Dude do you think the topic of this thread matters? None of this shit is going to make the difference between your hardware thermally throttling unless you royally fucked up. It's just an autistic hobby to get lower number or less noise

>>105748270
anon just cover the mesh with something like black construction paper. Unless your gpu power cable is going to catch on fire, then use a different material

>>105744417
>big fans are loud
>let's replace it with a little blower fan that has to squeal at 9999 RPM for meaningful cooling

>>105744362 (OP)
Top fans are fucking pointless at best and a detriment at worst.
It has been proven the best airflow pattern is a straight flow-through to produce a wind tunnel effect.
Obviously GPUs tend to fuck this up to some degree, but it's still better than fans every fucking where in all directions.

>>105746417
Yeah I thought that was a dumbass move when I did it on my PC about 6 years ago as a shitty compromise for a shitty problem I had, but it ended up working really well. So I think they're on to something.

>>105744362 (OP)
my case only has 1 fan though

When are we going to start doing this? You get the intake fans right next to the cpu and gpu with outside air. It has to cool well. The bottom fans draw air from the back and side of the shroud. Works on windowed cases.

>>105744362 (OP)
two top exhaust is better. i tested it in my case. ops pic is only better when the gpu is idle. when the gpu is under load then two exhaust always win.

imagine not being a bafflechad in 2025

>>105744362 (OP)
Wrong about what? My case doesn't have top mounted fans. Just a delta on the front and a delta on the back. Yes it's noisy when it's hot out but on cool days they run at idle.

>>105748405
I guess I could cover it in some sound absorbing foam.
But to be honest I don't care too much about the thermals of that rig because I use it mainly for multimedia and light gaming in the living room.
The aesthetics is the real selling point of that case, not the performance.
My real gaming rig at my "battle station" is a Fractal Torrent.

>>105748496
forgot to add that the gpu exhausts some in the back, but it depends on the type of gpu. Most exhaust is the width of the gpu and the front has a opening in the backplate for passthrough. You could deflect the rear exhaust down so the rear fan doesn't intake as much.

>>105744417
I'm posting from an M900 tiny now. It is quick enough for shitposting but that's about it. That said I rarely ever hear the little fan on it, only when I'm encoding a video on a hot day. The rest of the time it's silent.

>>105746417
i place my pc underneath my desk so i'm worried this might happen. is it really a thing? i'm able to move the top left exhaust closer to the the back and even 3d print a tilted spacer for it if needed

>>105748500
someone needs to make a case with a modular duct system that fits most but not all components. It doesn't have to be a perfect fit. Also exhaust duct can be ignored for how complicated it makes everything

>>105746708
what does the riser do in this config? i think they released stl files so you can 3d print them so i might try that.

>>105748496
That layout also makes more sense to dissipate the heat into the room instead of having it accumulate in the corner where the PC sits.
No idea why front to back became the norm.

>>105748528
a hard material + shallow absorbing foam is going to block sound better because it'll reflect back and forth between the walls of the case. The high frequency anyway

>>105748563
just grab a few sheets of black foamboard from hobby lobby and make custom baffles yourself. you aren't a DIYlet aren't you?

>>105748579
Yeah I was thinking about that the other day, the goal should be to put the heat between your AC supply register and your bedroom door. Instead we put the heat behind your deck lmao

>>105746417
You could get one of those magnetic heater vents covers and redirect the hot air rearwards.

>>105748500
been contemplating this but my gpu is a typical 3 fan model like the noctua one in OP's image. should i just duct the CPU cooler?

>>105748500
3d printed one of these that direct airflow into a concentrated beam. should i place this between the front intake thats aimed directly at my cpu air cooler?

>>105748500
I just use paper. it's good enough. unfortunately the GPU pass through baffle doesn't do much

>>105744362 (OP)

>>105748500
that's fine, but there's other shit that's missing airflow. like RAM/VRM?

>>105744362 (OP)
It only works for Noctua fans, since they're hyper engineered.
Try this with your run of the mill corsair shitfans and youll get different results.

>>105744594
Learn abot thermodynamics, the fan push cold wind.
So normally in most cases is.
>one fan to push cold wind.
>another fan to extract hot wind + dust.
Simple as that, sadly most pc builds only come with wind extractor which causes overheating after time.
>colder inside increase electric signal flow.
>pushing cold air increase duration of parts.
>having only extractor deteriorates hardware faster, along reducing performance.

>>105748712
what kind of temp improvements did you end up getting?

>>105749321
almost 10 degrees on the CPU, but I'm running a p620 with a bad (underpowered) cpu cooler that comes stock with 5945wx. I baffled the case fan I installed in the 2 din bay thats got a bloweymatron rate limited by fancurve so I dont blow out my eardrums. however, fan curve does a lot of heavy lifting on its own, I can find the sweet spot of what my ears can tolerate vs what the machine is capable of baring temps wise. I found that the baffle I set up to push gpu air up into the top part of the system for expulsion in the exhuast I have set up was basically nothing. I might put it back in again and double check, but right now I am just thrilled I can get my room cooler with some tweaking. the main reason to cool my CPU which ran at a comfortable 60 down to a 47? becuase I want my fucking room to be less hot. I find that the thing radiates on the case if I dont get the heat off of it. the GPU baffle isn't like the one above. it's designed not to funnel cold air to the GPU. it already has LOTS. but its designed to push the air it uses UP into the exhaust area so that it doesn't get recycled by the system. meanwhile the baffle for the CPU is meant to counteract this and make sure the CPU is drawing in cold air. however like I mentioned the baffle didn't do much to change my temps.

>>105748496
>blow hot air on the user
retard

>>105749444
please explain how blowing hot air on the wall behind you will not eventually heat you, it needs to be blown where it can be removed from your space entirely

>>105749433
>but its designed to push the air it uses UP into the exhaust area so that it doesn't get recycled by the system
any chance we can see this implementation? i have an NH-D15 that's probably slurping up the GPU hot air from below. I might consider closing that shit up with something 3d printed (assuming it wont melt).

>>105744362 (OP)
I just swapped out an old hero 8 for an am5 board. Took the kraken out and cleaned it up. Managed to put it back together with the fans blowing in. I'll fix it eventually. Havent put the panels back on yet. But pic related was what i was thinking since i cant get to the top front fan without pulling out the whole thing.

>>105744362 (OP)
I have 99 problems, but heat management ain't one.

>>105748496
the issue with that is that GPU core is right under the back GPU fan, and the GPU blows the hottest air out the side to the case wall causing it to rise right behind the CPU cooler. Because of that, doing a reverse flow will actually ingest hotter air than doing the typical front to back airflow.

>>105748656
If dropping your CPU temps 3 or 4 degrees is worth it.

>>105748579
A modern house would have proper ventilation to make that a non issue.

>>105748500
I'm not buying a $1000 + tip 3-D printer for this.

CQB bros how we handling this?

>>105749582
I call bullshit on this because heatpipes are so fast, but if you've seen in on thermal camera or something i'll take your word for it

You could also duct a rear intake a lot easier to fix that entirely

>>105749582
>>105749668
also does the pci express connector blocks that area. There's like 2 inches behind the connector for air to move through, and that's not particularly close to the gpu anymore

Meanwhile stuff like power delivery is further up on the cord and that gets pretty hot

>>105749692
further up on the card*

Try placing a plastic bag in the top front slot (a dust filter cover will help here) and see what that does for your CPU temps. Turn up the power to your front fans instead.

There's no evidence that anybody ever used it as an outtake at that spot. It's obvious that it would just eject cold air.
It's mainly intended for radiator mounting.

>>105745884
Why didn't he test using the top back fan as outtake and not using the top front?

No! You must buy poop fans!

I'm still rocking an FT02 with 9600x and a 9060xt.

Apparently modern heatpipe GPU coolers dont like being upside down like this but for such a pissy little card it doesn't matter.

All the fans are dying so I have replacements coming in the mail right now and I replaced the front panel connector with a new USB-C version.

>>105752549
You don't have dust filters?

buy AIO CPU cooler and never need to worry about a fan again

only faggots use cases with glass side panels and psu shrouds.
