[@chokeeweebee]

the problem with ATX right now is that the hottest workload for typical gaming pc's don't ever stress the CPU it's often the GPU that has to work 100%, this is made even worse with tempered glass side panels and the power supply shroud so really intel and AMD needs to work together to create a slightly modified reference architecture or case manufacturers standardising PCIE extension cables to create a layout that is actually designed for gaming workloads.

[@OTechnology]

Yes I agree very much on this

[@EmmaHopman]

This is the first good criticism I've ever heard of ATX. Interesting

[@ObsceneSuperMatt]

Even if both are running 100%, you have a 140-watt CPU and a 370-watt GPU, it obviously needs triple the airflow as the CPU.

[@Tadders]

[@807800]

It's already been solved. Just get a case with an open bottom intake, so the PSU is either at the front, top, or behind the mobo in a separate chamber.

[@kasimirdenhertog3516]

I wonder why a cooler design similar to the NVIDIA Founders Edition found on RTX 30 and 40 series cards doesn’t get used more often. All board partners have the same basic design, where two or three fans blow air onto the heatsink and then it vents out from the sides of the card. Whereas the NVIDIA design is really clever, having one fan blow onto the heatsink, but the air gets blown out of the case (like a blower style card) and the other fan pulls air through the heatsink and out the other side of the card. That way, half gets vented out of the case immediately, and the other half creates an air stream that you can utilize and enhance by mounting top or bottom fans - in contrast, the fans on other cards vent air to the sides, ie. towards a sheet of glass or the motherboard, so pretty useless.

[@yoadknux]

On my H500P Mesh + 2080Ti FTW3 one of the main thing I noticed is that vertical mounting lowers GPU temp by about 6c under load. With standard mounting, this card is designed to intake air from the bottom fans and exhaust from the side. Unfortunately for most cases side exhaust is blocked by glass. Vertical mounting gives more room for the heat to be exhausted from the rear and top fans. I miss the days we had side fans like in the Thermaltake Element S. Or the Enermax Chakra, which had a button that could flip the side fan from intake to exhaust.

[@DjRavix]

Interesting It’s basically the restriction at the back that forces the air downwards and then it gets sucked up by the GPU I actually remember that in the past PSU’s were always mounted at the top of the case … in some case you might still see the cutout for the 80mm fan that used to be on the back of PSU’s … then they moved to bigger fans on the bottom side of the PSU’s … I believe there were some issues at that time where some PSU’s overheated because of the case design with the top mounted PSU’s And that is when we started seeing bottom mounted PSU’s so they could get fresh air from underneath the case and the power cable would not have to run to the top of the case And than some company’s came with the PSU shroud that basically hides the PSU and cables … I actually like the approach that cases like the Enthoo Primo, O11D, HAF 700 Evo and some others have taken where The PSU is mounted behind the mainboard tray (or at least has its own compartment but doesn’t block off any bottom intake possibility’s) Yes it makes these cases wider but it also allows for HDD’s, SSD’s and small controller units to be hidden away from the main chamber I think this would result in a best of both worlds scenario and might be the best way to go for manufactures moving forward

[@RacingRalphEVO]

WOW! THANK YOU! That's so obvious when you talk about it yet I didn't think of it! I have a Corsair 4000D airflow case with two bequiet silent wings 3 fans mounted as front intake. After watching this video I switched them from top/middle to middle/bottom positions (the bottom fan blows into the psu shroud) and this alone dropped my gpu (RTX3090 FE) temperature from 74*c to 65*C in Unigine Heaven!!! That's just unbelievable. PS CPU temps have climbed a few *C probably because the tower cooler now misses a fan blowing cool air directly onto it, guess I'll have to buy a third fan some day but this doesn't seem to be a problem for now - it's much easier to cool anyway.

[@OTechnology]

Yep. You really need some direct airflow into the area where the GPU fans are intaking air.

[@24tommyst]

Got the Torrent Compact and added two fans at the bottom for intake and one in the back for exhaust. Running my 3080 beast at 65 max ;) and loving it. Smart case design matters.

[@meat-head-213]

Lancool 2 Mesh does a great job of GPU cooling with a PSU shroud. Especially when you install fans on top of the shroud.

[@oceanbytez847]

I saw my best thermals for GPU and VRM's with a side panel intake. The downside is that this cost me the view of a glass panel. If your all about performance definately go for a side panel fan.

[@Lord_of_ChaoSan]

It's not a flawed design, it's a negative pressure case and works as intended in the stock configuration. I have the older h500i and it's a similar story. I've optimized my setup since I got it about 5-6 Years ago so it does well as I have it. I'm running positive pressure as well, but I needed to block off certain areas like the back PCI slots that aren't populated- taping over the PCIE case slots stopped the positive pressure from pulling some of that hot air down to the gpu- it was drawing the hot air from the CPU down since there are holes for the air to escape from below the GPU ( I even tried zip-tying a small case fan to the back- just plain taping over them worked better). Once I taped over those holes temperatures went back to normal. I really love this case, but it's kind of strange when it comes to air flow. I've got a 240AIO with push/pull so 4 120mm fans on intake, 2 for exhaust, x1 120mm and x1 140. I've even got a hefty overclock on the CPU and it still stays very cool. I love NZXT cases, they're my go-to case manufacturer! Tape over those slots beneath the gpu if you add fans to the front and go positive pressure!

[@Hjominbonrun]

I found that closing those random holes on my case has decreased temps due to the fans more quickly flowing the hot air out and giving a higher pressurised path for the air to follow. Meaning it goes at speed. When there are random holes, it causes a lot of undirected air to just mill around and soak the components due to a lot of slow moving air floating around. Also creating a shroud tubing from the intake case fan to the intake of the cpu fan will result in there being less turbulence, and faster flow of cool air directly from outside the case.

[@davidferreira3801]

Great video! As soon as I watched his video I thought it was weird. Something like Lian Li O11 Air (Mini) is the perfect solution, every part can get cold unrestricted air, even the PSU. On a Fractal Turrent the PSU gets recycled air from CPU/GPU.

[@OTechnology]

Yea the O11 is a good case as well but speaking in terms of standard single compartment cases the Torrent is the best.

[@South_0f_Heaven_]

Proper fan size along with placement and varied speeds is what creates a case that flows well. Don’t understand cases like Corsair where they have the three side fans that do nothing but disturb the airflow. Front and bottom fans run slower while rear and top fans run faster keeps the cool fresh air moving as it should. Most of the PWM fan hubs are useless as they run all the fans at the same RPM regardless of the fans CFM.

[@themarketgardener]

You’ll get negative pressure if you make the exhaust fans run faster than the intake fans

[@doniscoming]

I’ve built 7 PCs in the last 5 years, 2 for me rest for friends - builds from 1000 to 4000usd and I keep saying - manufacturers need to agree on changing so many things in PC building space! PCIe slots are bending cause of thickness of gpus, power cables are sticking out in front of the window panel - stull like that needs to change in upcoming years. Nvidia new 12pin power supply connector is nice but i still dont like its from side not from the back of gpu ;)

[@karambiatos]

you pretty much need a full tower these days for modern GPUs anything else you are getting a bit sweaty with all those cables.

[@Metaris]

100% w you on the Torrent. It's a brilliant design, and I hope we see more like it. GPU thermals are really important for gaming.

[@spikestips6034]

A cold air intake in your Honda civic doesn't add horsepower it actually takes away 1 or 2 horse power. Even with a fan blowing in front of it while on the dinotester. The teachers prooved us students wrong at U.T.I. in order to bring the temps down you'll need to have the fans right over a hole in the case so outside air is directly getting in and not hot air from within side of the case.

[@r.d.6290]

The problem with negative pressure and the GPU getting "fresh" air from the back is that the dust doesn't get filtered out of it.

[@everope]

Pro tip: put an intake fan blowing into your open PCIe slots, difference of a few degrees for me!

[@friedmule5403]

Great video! I was thinking if a small 80 mm fan as intake from the rear could have helped? In that way do it still keep a positive pressure but "compress" the air under the GPU.

[@KiraDenys]

This just reminds me why I'm still using my 7 year old Corsair Air 740. Front 3x120 intake, bottom 2x140 intake, Top 2x140 exhaust, Back 1x140 exhaust, a 92mm Exhaust fan in the PSU compartment, and a 92mm Fan VHB taped to the HDD cage in the PSU compartment to keep air moving over the HDD's. As long as I can keep getting components that fit in my Air 740, I'm going to keep using it...

[@scottym.9077]

I just built a system in a Lian Li LanCool 205 Mesh case and it's interesting to me how cool it's running, despite using a single fan air cooler. I ran the TimeSpy stress test just last night. Even with some overclocking applied to the GPU, it only rose to 63 degrees at peak. The CPU rarely even rose above 50 degrees. The LanCool 205 Mesh is a far more open design and seems to promote far more airflow than the NZXT case used in the test. It really seemed like the system in the video suffered from a lack of airflow around the GPU in general. If I recall, the GPU didn't have much clearance between the edge of the card and the glass panel, which would only increase the severity of the airflow "dead zone" in the bottom of the case. The components I used in my build are as follows: ASUS ROG STRIX B550-F Gaming MoBo Ryzen 5600X ASUS TUF Gaming 3070 Seasonic Focus GX-750 G.Skill Trident Z (2x16GB 3200) 1TB NVME SSD (Yes, I understand that these components do not use as much power or generate as much heat as those used in the test, however I do think it represents and interesting point of observation.)

[@8lack8bird]

you could make the bottom psu + cover work, just embrace the "negative phenomenon" seen in this case. 2 exhaust fan on the front, nothing on the back, and (presumably better) solid tops for that straight wind tunnel flow. this way, you may have your solid front panel back (as long as the frame openings surrounding the fans are sealed)

[@OTechnology]

Still not ideal because the PSU would be exhausting its hot air right below where the PCIE slots for GPU intake are.

[@8lack8bird]

@@OTechnology iya bener juga sih

[@jorrelrivera1460]

Experienced this issue in my case with triple intake front fan and one exhaust at the back. I was able to resolve the issue by setting a different fan curve for the bottom front fan. Making it spin faster than the middle and top front fan prevents the GPU from recycling air because of the higher pressure from the bottom.

[@bolulembut1132]

did your problem resolved even with solid front case? i also have same issue + quite big gpu that make it worse 😢

[@EliteRock]

Worth bearing in mind that often the goal is positive pressure to _stop_ air being pulled in anywhere except through filtered intake fans (i.e. NOT though the PCI grille or any I/O panels). With a typical 2/3 front fan and single rear exhaust this does exactly what you say, results in very little air flow in the bottom/rear of the case around the GPU. In view of this, as an experiment I recently had a pair of 25mm deep honeycomb vane grilles printed for the front two fans of just such a compact ATX case which had the effect of dropping GPU temps by 5-6°C while raising CPU temp by about the same, because the straightened flow now easily reaches under the graphics card, which sheds more heat into the case so the CPU runs hotter. However, CPU cooling was never an issue and they both typically stay under 60°C (previously it was high 50's CPU and low/mid 60's GPU with both loaded).

[@backpain100]

Another good case is actually an ITX case, the NR200, with the power supply having its own fresh air on the side. The GPU intake air from the bottom, the CPU can take air in from the mesh side (or the back, if you use the rear fan as intake), and you can exhaust the air out the top. This is the ideal situation with each component getting its own fresh air. There are other cases that use this design principle. Meshlicious is another one with very good temp for the components.

[@OTechnology]

Yes I agree. Actually a lot of SFF ITX cases have this ideal independent airflow.

[@b0ne91]

Have that case and love it. GPU fan curve turned up to use it as intake and a 240mm AIO as exhausted to the side, right above GPU. Since it's just gaming workloads, my temps are more than fine.

[@viralprimenetwork]

Great insights, really good to watch this kind of videos before buying or planning to build a gaming setup. Thanks!

[@0MeALot0]

Having the aio radiator in front of the pc isn't ideal too as it would dump all the cpu heat into the case. Unless the pump is situated in the radiator you would want it to exit its air on top of the case. You cannot do that with the psu on top.

[@Spinelli__]

Never getting rid of my Cooler Master HAF 932 case. One of the coolest temp cases in history even to this day.

[@nigelwillis345]

Makes complete sense to me... I'm using Bequite Dark Base 900 Pro Rev.2 case fitted with 2 x 120mm Bequite Silent Wings 3 2200 RPM fans at the bottom of the case, they keep my GPU between 26 C no load to 56 C under full load with a positive upward air pressure. GPU cooling is becoming more critical with bigger more power hunger cards, keep cool and your GPU will last :)

[@NectarGaming]

so its pulling air from the psu upwards? Im trying to cool down my pc and im in a tropical country. I need to cool down my gpu thermals.

[@MrClauried]

@@NectarGaming after watching this video, im thinking about flipping my front lowest/3rd fan to make it exhaust, to lower the pressure atleast in the bottom part, for my GPU and PSU to effectively pull air from behind.

[@adeptgamezone8457]

​@@MrClauried if you do that it will not provide cool air or any air to the GPU if you have bottom fans you should place it in a way it intakes air from bottom of the case

[@glenben92]

Flipping the airflow so it intakes from the rear and exhausts at the front would be better in this case

[@oktc68]

I've built in a few different cases over the years, by far the best for thermal management, ease of build and with moderate flexibility has got to be Corsair's Carbide 540 Air, the twin chamber design means that the majority of cables and PSU are hidden, you retain the possibility of a 280mm top mounted radiator, in my experience better than a front mounted 360mm which dumps the heat back into the case rather than straight out the top. The GPU has vents below and to the rear. I get very good temps compared with builds of the same components. Case needs to breathe.

[@Shallizar777]

Whats actually weird is in all tests I've seen the H7 flow has worse cpu temps, but better GPU temps (while having a bottom psu) when compared to the Torrent.

[@siputai4321]

[@OnyxIdol]

I just ordered myself a single exhaust fan in the hopes that it will help lower my GPU temps (it's a 1660ti which doesn't get too hot but rather too noisy). Sounds like that could actually work!

[@RonnieBowlsby]

Interesting, I have 3 front intakes, AIO 2 fans top exhaust, and 1 back exhaust.... I experimented adding un intake fan in the under de GPU, near te 2 front intakes, and boy, keeps the GPU massively cool, always leaving that space under the GPU to naturally exhaust the hot air through the mesh panels, its amazing what air pressure can do, keep in mind, every case is different, you need to experiment. Fan speed for each section is also something to consider.

[@paranoid9678]

that why i have 2x120mm fans in bottem front + 2x140mm aio fan on top and a 1x140mm an at the top back so far it work fine also fans are not the only thing it about what kind of fans you use and at what speed ""older"" fans are design for two special functions air flow or air pressure, modern case fans are designed to deliver a mixture of both then there is speed intake fan should be slower then fans at the back or top but dont sets the fans that blow the air out not at maximum speed! since especially with fans that are designed for pressure, as these block themselves at a certain speed and thus offer less air throughput

[@op3l]

I bet if you jam a cardboard on the top of the backplate of the GPU to kind of make it a separate compartment, then make the bottom front fan an exhaust, the GPU temp would go down too.

[@OkieDokieSmokie]

I have my rear exhaust fan flipped to intake, all the pci slot covers off and the bigger cover that goes over them and my front 3 fans are exhausting. It’s dusty but it certainly doesn’t let anything build up. there is some recirculating from the gpu exhaust though but it cant be much with this much airflow

[@JSFrederic]

I wonder would the whole dynamic change if AIO was used for the cpu? That way the heat is blown out by the aio fan and there will be lesser hot air circulating. I also wonder is a 60,80 mm intake fan at the rear just just the gpu will help to get fresh air into the gap and reduce gpu temp

[@SemiMono]

Turn a top psu case upside down and you get a bottom psu but with the same layout as the fractal case.

[@eva-0162]

I did a test covering passive air inlets that do not have fans and the turbulence disappeared, when the air flow meets the incoming air from passive inlets they tend to collide and ruin the flow.

[@lingerlee4236]

So does that mean if I use the standard configuration with PSU at the bottom, front fan intake, rear+top fan exhaust, it's better to keep the case negative pressure, so cool air can be suck into the case from the PCIe backplate or the bottom mesh even though there are no intake fans for the bottom area which is right beneath the GPU? In my setup there is only one intake fan in the front and 3 exhaust fans (2 for AIO on the top and 1 in the rear), all 12cm ones. There is an extra slot for intake fan in the front, and to keep the high negative pressure, I shouldn't install another one, right? Besides, since there are 2 slots for intake fans in the front, does it matter which one I use? I am guessing if the fan is in the higher position, the air coming from it is more likely to exit the case directly without circulating inside, faster airflow will cause lower pressure and then cool air will be suck into the case from the bottom; while if it's in the lower position, it will provide intake air for the GPU, but then create much more complicated turbulence and it becomes extremely hard to decide if it's beneficial or not without a simulation.

[@kalamatagames2631]

The input airflow must be more than the output flow , if you put huge block of metal the air can't flow to they output fans , i have 12600 at 55 decree at100% use and gpu 3060 at 80% use at 70 decree i think i know something about airflows

[@OTechnology]

No its more about where you place your intakes and exhausts for most cases. For an O11D the best config for GPU temps would be all bottom intakes and everything else exhaust like your example of 3 intake 6 exhaust because all the exhaust fans are pulling air away from the GPU as much as possible. But the CPU temp might suffer from sucking in hot GPU air if you have a water cooler. So personally I think the best compromise is all bottom intake and a side intake for the CPU water cooler and top and rear exhausts.

in theory yes...but again...having such airflow as perfect as possible would require shifting most motherboard components vertically instead of a traditional horizontal build ( front to back air flow design ) the best vertical airflow you could have is only bottom and top fans, gpu mounted vertically and modded so it only pushes air upwards ( block bottom and side exhaust route )...and for cpu, an aio would generate as less turbulance as possible in the middle area while keeping it's warmth out the case other than that...i'm not a hardware engineer but as for vertical airflow...i guess nothing could beat that...as long as air pressure stays positive ( more intake than outtake )

[@qT_p13]

Higher gpu temps were known to be an issue ever since basement power supplies and psu shrouds became a mainstream design. However it looks better than the old school designs with top psu and cables hanging down all over the place. Also i don't think the industry puts too much focus on gpu airflow the way it does cpu airflow, as big gpu coolers are generally good enough to keep the gpu from throttling, and smaller gpus can just ramp up fan speed to noisy levels and the temps will be alright. At the end of the day though, components don't really care if they run at 65 or 70. As long as it isnt throttling it isnt a problem. New video from you. Long time.

[@CaveyMoth]

The bottom-to-top airflow pattern is the best, especially with all of these new passthrough GPU heatsinks. I'm tired of all of these giant basement dwelling PC cases that have the graphics card crammed into a corner. Why does the basement have to be so huge, anyway? How many cables and HDDs are people cramming in there? Why can't the PSU be worthy of being showcased? My second favorite airflow pattern that's becoming popular is the Lian-Li 011 Dynamic side exhaust style. If you are using a vertically mounted graphics card with a passthrough cooler, the hot air should exhaust directly out through the side vent. This is much better than a lot of cases that choke off vertically mounted graphics cards, especially sandwich form factor SFF cases. Stop choking the hottest component in your PC, people!

Even though I'm doing my bachelor in EE, but I'm whole nerd on mechanical engineering since class 8 and having tons of knowledge of different sectors. Even tho my bachelor program also contain this semester Mechanical course on fluid machineries, turbines (steam and gas), ice, boilers and so on..

[@OTechnology]

Yea no that is completely different. Pressure differences is not turbulent air.

[@KingKong-xp6so]

Dude, had you ever have any fluid mechanics course in your bachelor? Or you're just claiming this out of your ideas?

[@OTechnology]

@@KingKong-xp6so Lol you don't need to know fluid mechanics to figure out what's going on with that case airflow.

[@KingKong-xp6so]

I don't even need to bring out the phenomena happening inside the case to call you out.. I'm just showing how you're wrong about an idea and claiming sh#t out of nothing..

[@Zetraxes]

Well In reality if that all really does bother you you can just build a custom water loop that cools the graphics card properly

[@OTechnology]

Yes but full watercooling is the minority in most computer builds.

[@CitizenTechTalk]

@@OTechnology agreed.

[@dovahkingqcclips6913]

high end solution require money...and not everyone want to spend 400$+ on a gpu water block + all watercooling equipment that is required to do so....remember...you gotta be ready to spend 1000$ for custom water cooling

[@N0N0111]

My money is on the GPU power cables blocking flow.

[@OTechnology]

Nope that has nothing to do with it. They're out of the way basically sticking to the glass panel.

[@N0N0111]

@@OTechnology I don't agree, you know the cable is going all the way down towards the motherboard. It is like 3 rods that are breaking the airflow, and turn into a turbulence wall restricting air to go towards the back I/o ports. I would agree that the air flow is very restricted already, cause the fan is hitting the gpu from the side. About 1/4 of the air is going down there but is getting blocked by 3 massive cable bundles. You can't say it has nothing to do with airflow, the cables are literally there.

[@OTechnology]

@@N0N0111 Nope turbulence again has nothing to do with it. A bit of cable with free space around it is not going to stop a fan's airflow. They are used to blow through heatsinks that are a much higher restriction without problems anyways. Again the cable is not in the way of the front fans airflow in the first place, you can see in how the smoke goes behind the cables in Linus' video.

[@N0N0111]

@@OTechnology Okay fine we both are not experts, hope some expert on YT picks it up :)

[@CitizenTechTalk]

@@N0N0111 Turbulence has literally nothing to do with it. It's the thermal capacity and dynamics of the case that suck. One roof mounted fan exhaust and one rear exhaust. That case would suit a 120'140mm Rad with also one exhaust fan to alllow for thermal circulation to begin with, not the honking air cooler that Linus used. Plus the two fans in the front would allow for balanced air pressure. This means that they GPU gets all the cool air it needs from the front and back and the case has enough capacity to move a lot more air in and out more efficiently. Thermal dynamics is a very complicated science. But use a bit of common sense and more space means more capacity for air flow yes? An AIO will allow for dual zone air flow. VRM's, RAM CPU cooling zone up top and the GPU getting all the air It can from back and front without it being parasiticaly being stolen from the air cooler. The case simply isn't designed for air cooling. It's a design which is utterly flawed but can be overcome with a 120/140mm AIO with a CPU and motherboard to suit where the AIO can be mounted ontop or the back exhaust and the exhaust fan also fitting in the top or back as well. That way you have thermal capacity and correct pressures from front to back and ALL components getting fresh clean air in and hot air exhausted at the same time all while minimising dust build up. The only issue left of the PSU shroud. You can overcome that with tin snips 😊. Or just accept the short comings of the case. There was more than enough breathing space for the GPU still using my example using Linus's example though. It comes down to knowing you thermal capacity and dynamics of your case and what WILL and WON'T be suitable for the case you buy. This is a 120/140mm Rad and 3 120/140mm case. The motherboard should be a mid to low end board with nothing more than a I5 or 3600x. 750watt PSU inside. The ram spec should also not be super fast (anyway its not needed for this spec build as well) to avoid unnecessary heat soaking in the top of your case with no ventilation.) The rest needs to be be ssd, no mechanical hdds as again heat soak issues. Saying all of that, It's a terrible case hands down and turbulence has nothing to do with thermal capacity or case dynamics it's just a byproduct of what Linus caused with that honking air cooler to begin with. I personally use a full sized tower and AIO on my CPU and also AIO GPU 😂. But I'm running everything at serious overclocks and all extremely high end from front to back plus Led's and capture card etc and a 1000watt PSU. My case is currently the Corsair 750D(High airflow), I'll be upgrading to the Corsair 7000D High airflow this year. Turbulence doesn't cause heat soak it just lowers cooling efficiency is all. Just always remember capacity and dynamics for case suitablity for building PCs. If it's high - enthusiast end bigger case is better but more cost and more fans. If it's a mid to low end build, mid tower to itx. An itx build for example I3, Ryzen APU, Nvidia 1050/1060 600watt PSU at most! Mid build as mentioned with this case and only up to a 3060/3070 or 6600/6600xt GPU.. Build for your needs not what KZbinrs show you. Especially micro itx case with a 12900k and RTX3090 and 1000watt low profile PSU for heaven's sake!!!! It will melt over long use periods and shorten the life off all components by up to 80%! You'll literally have your PC for six months before you need to replace almost everything with a brand new build. I hope this covers both discussions you are both having sufficiently. Kind regards, CTT.

All of this for RGB. How much must we sacrifice for the RGB gods?

[@Pertamax7-HD]

[@LeitoAE]

These are not cases flaws, these are ATX mobos and GPUs design flaws. GPU started as simple addon card without any heatsink. It is plugged in into motherboard just like any other extension card, like additional USB card, ethernet card, audio card. The GPUs grow to very complex devices, drawing a lot of power and generating tons of heat. The truth is that the maximum power of GPU should be the power from PCIe slot. If you not exceeding that, you don't have heat problems. If we put high power GPU, we block it's airflow by GPU itself. We put it upside down. This is the dumbest idea ever. The only way to make a proper airflow GPU while still using upside down mounted PCB is to make it 5 slots and rotate fans so they move air like CPU coolers does. Tower style GPU cooler with 3 or 4 fans taking air from front of the case and exhausting at the back next to video output ports. Other way is to use PCIe extensions and mount GPU somewhere else, like many case manufacturers are starting to do.

What you and Linus are saying are both right I think. This because the air circulating inside the case on a system level (the case) is also called turbulance, I think. Don't know for facts exactly, but I think Linus might have been thinking so as well. You just get the fundamental reasons and mechanics quite well here I think and also helped me understand pc case airflow better. Haven't watched the full video of Linus so can't compare otherwise.

[@NeutronicalGaming]

Guys, this is how linus makes money. he makes a dogshit wrong video with hacky bullshit in it, then he makes a clickbait title for it, then he makes a follow-up and an apology piece that you also watch out of self satisfactory self righteousness, and bam he just made you watch bullshit for an hour and 3 of his videos. Nothing here is new, this has been the repeating cycle since the channel was born.

[@OTechnology]

No I don't think he did it on purpose, it was just rushed out. Maybe because it was an NZXT sponsored video. Other commenters also mentioned they were hoping for a more thorough video with testing using baffles and different fan configs.

[@NeutronicalGaming]

@@OTechnology no offence but he did exactly the same thing with : Thermoelectric cooling, corsair's fan/case flow cfd argument, liquid metal in various devices, aircon cooled pc, fridge / freezer cooled pc and debunking myths on watercooling / radiator size / /stacking in every single case he made a quick and dirty, arguably wrong video, then corrected it, or added *expert opinions* or called in steve from gamer's nexus, or some other youtuber to make folloup pieces, custom hack hardware in his inhouse lab to try and prove some point or another. now once is a mistake, twice is a coincidence, what we have here is a psycopathic tendency over a career to mislead people into clicking on multiple videos to resolve a question or situation he instigated.

[@OTechnology]

@@NeutronicalGaming True he did make a lot of wrong conclusions to flawed testing. Like how I also made a video on the water vs air cooling test that he made that was also broken.

If you want to do a video on a product, and Gamers Nexus has already done a video on it, it is always going to be in your best interest to watch that video from Gamers Nexus before.

[@CitizenTechTalk]

Simple solution: AIO in the top (140/120 mm) Same with the exhaust fan. 2 in 2 out right? Plus really crappy case to begin with 😂. Basically it's a budget build case to begin with, not a high end build. All I'd put in there is a budget 3600x board and CPU. 120/140mm Rad and exhaust fan with a 3060 and 750 watt PSU. 2x front fans etc as well. It's not a case suitable for high end components at all!! And yes terribly designed. NZXT need to steer away from case design and keep doing what they're doing best still. And that's NOT case design 😂.
