True story here. My 8 year daughter just walked in and saw me watching this video, saw your face and asked "Why are you watching this movie again?" and I replied "What movie?" and she said "Guardians of the Galaxy"......

Human eye can see only 2 fans

If Jack Black and Chris Pratt had a kid... You would be that child 😂... Love your videos brother.

This video has seriously saved me soo much time. Thank you for going through all of the hard work and testing to find the optimal results! Thank you, thank you, thank you!!!

what a Cool project

man i love your work Dmitry.

I loved this experiment!!! I'm building a pc in an O11 case in the coming days and this really helped me with the fans. I was wondering how double-stacking the rad would affect temps though. And where to put the double-stacked rad, on top or on the side. Thank you very much!

This is a great explanation, especially for rookies like me. Thank you for sharing!

Just keep in mind, that the results for the version "AiO in Top, exhaust" might be very different if you use an open shroud GPU instead of the Blower Style one. (More GPU Heat inside the Case)

If this is the best case, isn't it always a best case scenario?

Jesus. I got 7 Fans inside my case and every time i start a good optimized game, my PC sounds like it tries to fly away.

This was incredibly helpful! I purchased the Lian-Li PC-011 and I was unsure about my fan configuration and this completely set me straight! I am going with the 9 fan configuration since I am not skilled enough to tackle water cooling just yet (beyond that cool radiator you used which seems simple enough). Many thanks!

Dimitri, "Best Case" Scenario - 10 / 10!

Great video, I just bought the Lian Li Razer case. I watched another video where he had 3 bottom intake, the AIO was at the top as an intake with 3 fans, and the 3 fans on the side were exhaust, he said that gave him the best temps.

"The O11 is the case of my dreams" *Shows NZXT H700i*

Thank you so much for this. I was doubting putting my AIO on top as the exhaust.

I'm loving the editing dude really nice work!! subscribed!!

7:27 best case scenario for fan placement and direction of airflow.

This is probably the best case ever made. It has a perfect balance between aesthetics and performance.

You got a lot of fans man 😆

4:10 I like how the power supply is separate from the rest of the enclosure to minimize heat transfer.

Interesting results. One configuration I've seen that works really good and gets similar if not better results than the best configuration tested here is aio on the top as intake, intake on the bottom, and then the side being exhaust.

When I place fans I usually follow 4 case airflow rules: 1. From the bottom and up, because hot air is naturally rising. 2. Front to back, because cases are usually configured like this. 3. Positive air pressure, as to prevent dust from getting sucked in via empty expansion slots etc. 4. Test every option possible because your system deserves a complete analysis! Who knows what complicated situations your case/room/desk/components can cause?

Wouldnt it make more sense to use a third party GPU that uses more than one fan and that is not a blower style card as they could use more of that air supplied by the bottom fans?

I really want this case for my watercooling setup, but it's not available in my country just yet. Ugh

Ivan doesn't need laptop, ivan puts 9 fans into desktop so it flys next to ivan

I saw a prebuilt system in this case on caseking. I did like they did and was suprised how great temps were, both CPU and GPU. Setup is: 3 bottom-fans intake, 3 side-fans outtake, radiator top with 3 fans for INTAKE cooling the CPU perfectly fine and the GPU still get its fresh air. Also installed a 80mm bequiet fan back above the lian li / der 8auer logo like they did. Case and rad-fans are TT Pure Plus. I also run a 6700k @ 4.5 GHz but a RTX 2080, which produces serious heat. Still Temps are amazing. GPU max 70°C w/ fans @ 60 %, CPU max 68°C with fans @ 20%. CPU been delided but w/o liquid metal. CPU cooler is an Eisbear 360 L with modded tubes and reservoir. Just adding that details to be fair.

I could listen to Dmitry say "fans" for hours. This video made me happy.

Your intros are always so sick dude

Sir do you have a cable management of this set up about the 9 fan and commander pro?

This video is great but as noted by several users the results set is incomplete because Dimitri completely missed one scenario for non blower horizontal GPU setup which probably is the most common scenario. I have tested further and can confirm 1) if regular horizontal GPU setup non blower style - best temperature hands down with: bottom intake, top AIO intake and side exhaust - even better if you push/pull your AIO with a 12 fan overkill config using the configuration above (yes you can do it with this case on top!). both GPU and CPU received fresh air which is evacuated by the size. My cpu is crazy cold in that config 2) if vertical GPU setup or blower style GPU , then Dimitri settings are the best

The best case review channel on the internet !

I use 3 top intake, 3 bottom intake, AIO side exhaust. Fresh air for gpu. (MSI 2080ti gaming x trio) And fresh air for the AIO from bottom and top front fans blowing down/up on the AIO fans. This for me was the best setup. Thank you for a great video as always.

This setup is what I have, so 3 bottom intake, 3 side intake and top AIO exaust, plus I bought 2 80mm ARGB fans and brutforce mounted them in the rear also for exaust. :D Love this case.

I've been looking for a tower to build my own gaming PC. This one has come up a lot in my research and I think I will be getting this one. I'm a first-time computer builder I'm excited to start this project. Thanks for the info

When I'm thinking about airflow I like to imagine the air as water in a tank that's being heated up, and then I imagine the best way to get water in and out of the tank quickly so that it doesn't get a chance to get hot. I find this helps me to clarify things because it's easier to visualise water because you can see it, while air is kind of invisible.. For example, if you have water flowing in from 6 holes, and it only has 2 holes to flow out then it will be hanging around in there for a while.

I just found the Lian Li case and it is now on my build list. I started looking at fan configurations, including with the Corsair H150i 3 fan AIO cooler..... and here I am at the perfect video to reassure my build design! Thank you!

*need help* Got that case and a MSI B450 Carbon pro + AIO and 6 Corsair ll120 Now I can’t connect the USB 3.0 from the case with the motherboard because the fans on the bottom are blocking it. Any ideas?

There's a one big PROBLEM in this result. Canucks used Blower-style GPU, so hot air from the GPU directly goes out of the case. It means intaked cool air goes directly to the AIO's top radiator and it makes CPU cooler. BUT most of us use Open-air GPU. If we set up AIO Top exhaust, intaked cool air goes to GPU and becomes hot air. It means hot air from GPU goes to the AIO'S radiator, and it decreases AIO's cooling. So I think the Best solution with Open-air GPU is . If you want to use only 6 fans, is the best.

Dmitry, I have been admiring your work for a while Sir. As a fellow interested in learning. What are your preparation habits? How much time do you spend preparing for the video production? If you feel like answering in a percentages or time frames style answers that'd be highly appreciated. Thank you and keep up the great works.

Keep in mind that if you do the side AIO setup, you can do a 6 fan push-pull configuration with a 360mm radiator setup which significantly drops the CPU temperatures down. Mine dropped 10 degrees C at 100% load from my previous 3 fan intake AIO setup on the side.

The outtakes at the end made me subscribe. Brilliant! LOL! I also have this case, and im in the middle of a build, you have just given me my fan set up. Only my build will house 14 fans. I'll leave you to ponder that, Keep it up good sir, good work.

exactly what i was looking for. Thanks for not clickbaiting and delivering what the title promised!

31 seconds into the video and I already gave it a 👍. You guys are awesome! 😂🤣😂🤣😂🤣

Intake on bottom and side exclusively. All of top should be exhaust. this config makes the most sense to me

you really should have tried with top rad intake, side exhaust and bottom intake, i have got really good results with this setup

It's such a shame you have to reverse RGB and don't get the full lightning effect on intake.s 6/9 of your fans are not displayed as they are "intended"

Havnt fully watched the video yet... but I suspect that 6x Intake (3x bottom, 3x side) and 3x exhaust at the top is the best config. Edit: Nailed it :)

Same conclusion as Gamers Nexus, 3 intake on bottom and side, 3 exhaust top= best thermals.

Wish you would've tested AIO on top, with all bottom and top as intake and side as exhaust.

"...best CASE scenario..." at 7:28... LOL

I would have liked to see side exhaust, top+bottom intake

How did you control the fan speed of the radiator if you could only plug your 6 fans into the Commander Pro?

Uh oh. I put 11 in mine. GPU 360mm radiator intake with push/pull on side (yes, you can fit CERTAIN fans back there if you put the radiator in the front), CPU 360mm radiator up top in a push only config (the fans were white, so I wanted them to show more than the black radiator to match the case) and 2 bottom intake fans to basically bring in some fresh air to mix with the hot exhaust of the GPU intake and to help cool the VRMS of the GPU. Using an i9 9900k @ 5ghz and RTX 2080ti with a slight overclock the max temps I see on the CPU are in the upper 70s (temps spikes are weird, seems like latency in the cooling chain rather than not enough cooling capacity) and the GPU maxes out at 57c. All fans run @ ~700 RPM. I use Argus Monitor software to set fan speeds (set the fans to peg at max if temps hit 85c on either CPU or GPU that way I'll know something's gone bad, since I don't have an internal speaker) and honestly, people should really look into that software. Dmitry would probably get a big use out of it. Not only can you monitor temps across EVERYTHING, you can set fan speeds based on temps of anything. Want a case fan to increase as your GPU heats up? You can. When your RAM heats up? You can. Want to use an average temps over time so your fans aren't constantly revving? Yup. You can honestly do an incredible amount for such an incredibly low amount, it's probably one of the best upgrades I've made to my computer. Oops, now I sound like a shill.

Thank you! This was just what I needed.

Top and Bottom both as intake with side as exhaust, creating positive pressure as the case has plenty of unfiltered areas to exhaust all that filtered air. Surprised that that wasn't tried...

would have love to have seen smoke to see the air flow but still great work like always!

I liked your video. Great photography and great energy! Preface: Server hardware design optimizes air flow by placing intake on one side and exhaust on the other. Component placement and orientation should be considered to avoid air restriction where possible. In the PC-O11 dynamic the GPU clearly creates a division between the top and bottom of the front side of the case. All the cables on the back side would create somewhat of a restrictions, unless you have them tidy. The dust screens all create a quantitative airflow restriction and so if you can maximize the filtered input area, you clearly create a better flow scenario. If you are still experimenting with flow options please consider this: 1. How about leaving the dust screens on the top (exhaust) to restrict exhausting heavily on the top. Optionally this vent can be partially blocked near the front of the case with a sheet of paper sandwiched between the case and the screen. 2. Cover the front 2/5th to half of the bottom vents with a sheet of paper; leave the rear portion of the bottom vents completely open. Perhaps a couple of magnets to hold the paper in place? 3. Place all 6 fans configured as intakes through side. 3 in front of the radiator pulling air into the case through the sided mounted radiator, and 3 in the back pushing air through the radiator. 4. You may experiment with the rear side dust screens in place or removed. 5. Optionally a single fan can be placed to exhaust air from the bottom rear of the case to help move more air beneath the GPU. This configuration will create a "U" shaped airflow pattern where air is introduced in the rear through HD area and also through the openings in the back side cover (optionally without the screens), then the air is all forced through the radiator and into the front side of the case. Then it is divided into two regions, above and below the GPU. The removal of the dust screen on the bottom will enhance airflow velocity beneath the GPU but not until the paper blockage channeled all air further to the rear displacing hot GPU air. The optional fan (#5 above) will enhance the air mass flowing in this region. Air is also flowing over the top of the GPU will exit partially from the top, and also through the openings in the rear. The liquids cooled CPU is effectively chilled by the entire air mass flowing through the case as the radiator is the focus of all 6 fans. Inefficiencies in this configuration would be openings between the front side (motherboard side) and rear side (PSU side) where air doesn't fully exit the case before getting forced back into circulation; the rubber grommets help reduce these inefficiencies but other large openings may present an opportunity to further enhance the configuration.

Thanks for the clear answer. I am building a system with this case and water cooling (my first time for that) and didn't know whether to suck things in or out and where. I like your comment about intakes on the sides and bottom and outtake (for the water cooler) on the top. The "humor" I could do without, but most of these channels seem to think that is a requirement.

3:00 You call that simple? Having two controllers and two cables for each fan? Thermaltake does it best at the moment with a single hub and single cable per fan. Now we just need someone to make daisy chain-able/connectable fans to eliminate all but one cable.

Man 9 fans! That’s cool......

Just started building my XL, you answered all my questions, and it was good to confirm the options I had been considering, thanks

Maybe I missed something but I feel like the obvious solution is to have AIO intake on top to get the best CPU cooling, bottom fans intake to get best GPU cooling and side fans exhaust to remove all the air that's been pushed through, and heated by the radiator and GPU. Is there some reason you wouldn't test this? Everything else pushes warm air through the AIO.

You have a lot of FANS

have you thought about picking up a smoke wand to see how air moves through cases?

Thank you so much for this video. I have been wanting to do an all fan build in this case and this helped a lot.

THANK YOU SO MUCH FOR THIS. I literally have the exact same set up and this was extremely helpful and saved me hours of testing time. Def subscribing

I'd like to see a test with no AIO - 3 top exhaust, 3 side intake, 3 bottom intake!

It's always important to keep the components inside cool...especially with all that many fans to spare.

I just ordered this case and parts to build a completely new system yesterday and was wondering how to run my fans. Thanks!

This is exactly what I was looking for. Thank you so much for doing this.

Bottom and top intake, side exhaust makes the most sence imo

This video and the original review are what is driving me to get the case. Thank you so much!

9 fans are awesome Dust: thanks for reviving me

This was an awsome video, exactly what i was looking for! thanks man!

1:14 to skip the built in ad.

I'm really surprised the gpu suffered so much when the AIO was side intake. Crazy that it benefits by 4 degrees simply because the side intake fans are unobstructed. I would have thought having unobstructed top exhaust fans would allow more heat to be dissipated, thus supporting the gpu's cooling. Very interested in how an open air gpu cooler would impact these scores.

Only needs 3 fans in total. 1. Air cooler for CPU with a 140mm fan 2. Bottom intake fan 140mm 3. Top exhaust fan 140mm Great video, would love to see results with my config as above!

*i have the same case and also have 9 fans by lian li. i have a Nzxt Z73 liquid cooler on top with 3 fans as exhaust and other 6 as intake. tempatures stay low when gaming and noise of fans is set on silent at 1020 rpm. i love this set up

I was thinking of doing exactly this. Should I? 😂🤔 I'll be getting the Ryzen 5 3600(maybe x) and the Navi 3080 (or 2070 if Navi doesn't perform). Mainly concerned about the noise, the system looks gorgeous!

9:08 My OCD is triggered...

very informative..thanks for the knowledge

The music was horrible when the boot sequence came in...

When I read the title for some reason i thought that he would have a giant case and let nine subscribers go into it.(idk why)

For me overkill fans just seems to allow less fan speed per fan to keep you from having to run a fan all out but that's just my experience once you start putting alot of fans in it

Thanks for the input. I have the same case, and i have my 9 fans setup like yours, except i had the bottom 3 fans as exhaust.

Would you perfer the ML RGB fans or LL RGB fans from Corsair

Meanwhile, my pc has been running for 6 years with just one exhaust fan 😂

Pretty sure I watched this video before, but I went searching and found it again. Just recently got the PCMR Version of the case, and was trying to figure out what fan setup would be good. Spent more on Fans than on the Case. Had to get the Commander Pro on top of it. I am a Corsair Sucker... I think my AIO went out (4 years old), because it reaches 80 C on Startup. I think moving it around so much is what killed it. Weeeee.

I just bought this case. Didn’t do research this was kind of made for water cooling. So I am tripping a little. Seeing this helped. I have a aio for my cpu. So no big deal. Worried about my 3060ti. Hoping the fans on it and in the case keep everything cool.

Nice intro

Thought this was an LTT vid when I was scrolling through uploads

Using a computer as a plant stand must be exciting when it's plant watering time.

This has more fans than a celebrity.

What if top and bottom intake then AIO Side exhaust?

I have 12 in mine 😂 3 Corsair LL120 RGB on bottom intake, 3 Corsair LL120 RGB front/side exaust, and 6 corsair SP120’s on a 360 Rad at the top in push/pull config.

Thank you for this video. I just bought this case for my new PC. Been trying to decide how I wanted to mount my AIO cpu cooler when I get it. Great data!

Just got this case and this was super informative! Thank you so much.

At this point, you should have a hovering pc.
