However, this doesn't affect the essence of what was said, because the text was written based on the correct data, and the error occurred during editing.
@@LucFireCraft He never intsalled the fans in the correct order. Front to back and bottom to top. If you install the fans in the correct way the temps are way better than without or his "Base" scenario with just one fan in the back.

Thank you so much for making this video. I had always wondered what config worked the best, and you have just answered it for me. I really appreciate your time and effort in doing this.
Thank you so much for making this video! While building a PC, my friend and I got in a disagreement on how and where to place the fans so I’ve always had the question in the back of my head with no good answers.
A summary/reminder at the end would have been golden. What was the best fan setup with all panels on in the "right side up"(non-upside down) configuration?
People are so overthinking this. Fresh air In from front and Hot air out from back. Adding extra fans to bottom or top just mess air flow. I use overpressure setup with 3 120mm fans at front and 1 120mm exhaust at back. All pcie slot covers removed from back. No dust collection inside case, runs cool and quiet
I have also found that less is more. I have two 140mm fans on my aio blowing in and one 140mm exhausting. My cpu and gpu throttle as much as they did when I had three 140mm fans at the top also exhausting or three 140 intakes and 1 back and 3 top exhausts.
After 20 years building these, nowadays first thing that goes to trash is the sidepanel. Open case always wins. No need for pointless fans either. Only coolers and ramfan for memory overclocking. It really doesn't even collect more dust. You'd be surprised if you never rock open case.
People are so overthinking this. Fresh air access for a good cpu cooler fan and the gpu fans is everything we need. Closing the case just messes with the air flow. I use the same open case since ~27years and vacuum it once a year just like the rest of the appartment.
This channels was randomly recommend to me by TH-cam, and i am so glad it did. I love it! Keep it up. These tests are really fun when you have a blower style card. My first ever PC that as my own had a EVGA 750ti in it. I was so proud! Almost physically impossible to get to hot. But got lucky and found a EVGA 1070 founders edition(An only recently upgraded from that! What a great card). I found with my crap case at the time that if I set all the case fans to intake and the one behind the CPU as a exhaust I got the best temps by far. An the extreme positive pressure kept the dust surprisingly low. I then went a little crazy and got a NZXT G12 bracket and a 120mm EVGA AIO and attached it to the 1070 and had a card that never got over 40 degrees while gaming.
Why? Totaly dissagree with you. Chase builders should finaly build their chases with own seperated "room" for the Gpu connected with a riser cable. Sitting at a angle where the air Flow can go with fresh air in and hot air out without coming in contact to other parts. Everyone know that the Gpu is the hottest thing and the cpu can be modded with extreme big coolers, which gpus cant. For me it makes no sense to hold on the old sheme.
Rear intake actually works extremely well for SFF. This is because the exhaust fan can be placed at the top of the case in very close proximity to the CPU cooler and you can pull air directly from the area above the GPU and in front of the CPU cooler.
Man, thanks for all the efforts you made. For me, the number 1 rule for case cooling is always seeking the cpu to have less hot exhaust from gpu, and the second is to make all exhaust leaves the case as soon as possible. So no matter what kind of components you have, leaving the side panel open would be a better option; If not, have a meshed side panel instead or maybe get a gpu with aio liquid cooler.
The hot air coming out of the rear exhaust always returns to the case. The important thing is to keep the return path of the hot air as long as possible. This is necessary for the hot air to cool down. When you put the intake fans on top, this path becomes shorter and the hot air returns inside without cooling sufficiently. This is why the temperature increases in the multi-fan experiments. (Also, when all the fans are used as exhaust, there is no air circulation and the temperatures increase again.) The hot air coming out of the rear exhaust can travel a long enough path to cool down using the front fan. Because this is the longest path. It is ideal to provide air circulation with the rear exhaust and the front intake fan. You have produced useful information for many people. Good work!
That was awesome! Yesterday I got so much hate against my open case design and today I got this video in my recommendation. Incredible how people think the "well-engineered" cases are for the greater good but NO, they are designed for to spend more money on accessories.
What a delightful video testing the craziest forms of fans, all in the name of science and curiosity. I'm even going to recommend that the biggest hardware channel in my country do the same experiment.
Three fans on the front, Two out through the radiator on the top and one out the back. No overheating issues but I did enjoy this video. Thank you for your time!
Thank you for answering all the questions I always wanted to ask! I really enjoyed watching this one and got soo much information that I'll never use. :) I aim for max silence, so I have two slow front intake SW3 and one faster rear exhaust SW3 to cool 5800X + 4070. Ironically in Define S2, as the original GB-14 were too noisy. But there's something more important than fan configurations: DUST. :) Case with a dust filter on any intake should always be priority, even on gaming rigs.
That was a hard work for us from you Roman. I can say, i have no idea about my Fans in my computers, but i did add and remove so long if i have the resoults i wish. So they are looking too.^^
I went with 6 fans in my current build. 3 intake airflow fans in the front, 1 exhaust airflow fan in the back, 2 static pressure fans on the AIO on top. I feel like the airflow fans carry the heat out from the 7800 XT and the CPU takes care of itself with the AIO.
For a case with a solid side panel, the best results I've ever encountered were achieved by removing the side panel. That was enough info to tell me, either run it with the panel off, or start cutting/drilling. If you have a negative pressure environment in your case, while having vents as close as possible to your main components, that cooler air will get drawn in naturally. Best results I've gotten are from one front low intake, one rear upper exhaust, one top exhaust, vented sides. Position drives or other components and wiring so they don't block flow.
I have almost the exact system! The difference is the msi rtx 3080 gamingZ 12g (which is very hot!) and cpu cooler is be quiet dark rock pro 4! Rear fan 14cm and 3 12cm top fans as exhaust, 3 12cm front fans as intake. I use the "Fan control" program to adjust each fan individually, including cpu and gpu fans. I recommend it HIGHLY! The most important case fans are the rear exhaust fan, and the rear top exhaust fan. All the heat accumulates at that corner because of the cpu cooler, which has to compensate the rising heat of the gpu also. I havent tried to install the bottom fan, because I still use the HDD tray below. When I have to play a game, I have a cooling profile which sets my fans to higher speeds (individually) to keep the system cool. Nice video!!
Extremely informative video. I will have to adjust my fans a bit to experiment with dust reduction and improved thermals with the knowledge you gifted us. Also, kudos on all the constant cable management you endured for this video, excellent work all around.
Увидел превью и уж хотел кинуть жалобу за кражу ролика, а это просто Рома тренирует свой английский и предает свои эксперименты более масштабной огласке) Так держать, удачи в развитии и этого канала!
It's also important to think about dust intake with negative internal pressure. Its better to have a slight possitive pressure to make sure the air is getting in through the filters of the fans
Not gonna lie, these are the kinds of questions I wanted answered. I built a PC that I designed to cool a 65W i7 passively with the NH-P1, but I decided it was such a neat build that I wanted it to be my main PC. So now I have intake fans for the GPU and to try to maintain positive pressure to try to reduce dust buildup in the full-mesh case, and my one exhaust fan only comes on when things are getting toasty (mobo above 40C and/or CPU/GPU at pretty high utilization). And yeah, I'm getting similar results to some of these where my CPU thermals are a little worse when the GPU fans and intake fans near the GPU are active. But my case is really well ventilated, so it only goes up by a few degrees. And I always thought the "hot air rises" arguments for fan placement were silly because fans necessarily introduce turbulence.
Some forgotten knowledge from years ago, PC's came with CPU Fan Duct, which dramatically reduced the overall system temperature, but mind you, GPU's at the time were pretty low power and even some of them had a passive cooler or a tiny fan... *Coughs heavily in Nvidia MX440*.
One of the best configurations i have found so far for an (old) case that does not have any openings at the top is 2 good 140mm (covered by lite mesh) and 1 120mm exhaust fan and removing ALL obstructions from the back. This walks very well cooling pretty high temp hardware 12400h (stock fan!) + 3080ti, on the cheap. One 140mm fan had a place for it, the other one i had to jurry-rig on my own in place of the old cd and floppy trays. The result is very quiet with fans configured to run up to 80% speed, moves a lot of air through the case and the exhaust feels burning hot to the hand. First tried without removing the back covers, it worked but it felt that there is too much pressure in the case, the situation improved drastically with every additional cover i removed. The exhaust fan is there is there basically to circulate the air then the pc is idle or at a very low load. The fans are old Noiseblocker NB-eLoop that have a very unique shape and have some unique properties, like a very focused current of air. They are pointed directly at the cpu and gpu, and are configured to ramp up with gpu and cpu tems respectively. Unexpectedly, the fan pointed at the shitty stock intel cooler improves the cpu temps insanely, it drops like 10-15 degrees when the cpu focused 140 fan ramps up and is practically silent if its rmp does not go over 85% of max rpm. I call this my windtunnel setup. The fan curves are set up via the FanControl software, it also works well for limiting the speed of the stock cpu cooler to make it no go into its whiny and low top rpms. Dont remember the exact temps but the cpu is usually under 70, and gpu under 85, they could go much lower if I allow the fans to go to 100, but this is the sweetspot for cool and quiet for me. (This was done to save money, i wanted to reuse as much of my older system as possible, and the only cooling parts i purchased were the two 140mm fans fro 15$ each)
In my configuration, I have a 360 mm AIO on top, a 120 mm exhaust at the back, and a 140 mm intake at the front. The question is whether another 140 mm at the front will improve the cooling situation.
the four fan test you need to include having the top right blowing in and the top two right blowing in, they blow cold air directly into the CPU intake
Very good video! I would have loved if you mentioned dust accumulation with possitive pressure and negative pressure configurations not to forget dust filtered intake vs unfiltered intake, etc. because i still believe dust filtered possitive pressure configuration is the best one overall.. :)
I know this isn't ment to be a serious video, but for those who want the correct setup; The fans should blow in the same direction, i.e. front to back and bottom to top. No fans should blow against another Keep the intakes together (front and bottom) and all the exhausts together (rear and top) Have filters on the intakes and at least one less exhaust fan to help keep dust out Edit; typos
@@Clashy69 A slight positive pressure pushes air out the gaps in the case, helping to keep dust out, You could have a 3+3 setup, but have a 240 radiator as exhausts, and the restriction from the rad would create positive pressure
@@AndroidBeacshire what if u just have normal 120 fans? is what i said still good or is it better to just have 3 front intakes 1 rear exhaust and then only 1 top exhaust?
I got XT VIEW case. Top 3x intake, rear 1x intake, bottom x1[GPU extra] intake, 2x back side exhaust. Custom fan curves on all, CPU tower fan to pull. No thermal issues without custom fan curves, however fans do ramp when gaming custom fan curve by design. G/HTPC sofa experience so fan noise doesn't bother.
I love playing with fans! I have a Tower 900, and I've been messing around with fan configurations a while. I currently have a separator between the gpu and cpu. Gpu side has intake on top and bottom (going to do more testing with that soon). Cpu side is top intake, and three exhaust fans blowing out the bottom. Top intake is working quite well. I get fresh air directed through a shroud to the cpu cooler, and it doesn't go over 70 at max load. 8086k delidded at 5.3 ghz
That's why pc layout of ''tower'' cases haven't changed since late 80's / early 90's because, it just works, what changed was addition of bigger fans, bigger heatsinks on components, removed 5.25'' or 3.5'' drive caddies and other features but, foundation itself - didn't
used different fan layouts in most of the pcs Ive built. Just more fun that way. I've found them effective enough, my main rig uses 8 intake fans and one exhaust, nevery have issues with throttling from a 5950x and 3090. that said I agree with you that "out of the case" thinking usually doesn't work as initially imagined
I recently added a fan as exhaust through the spare PCI slots (my aftermarket GPU cooler JUST permits one to fit one between it and the slot covers), helped a bit (without dedicated testing), likely by getting more intake to reach more of the GPU cooler fans and keeping more of the GPU exhaust away from the CPU cooler. Though I also added intake and exhaust fans to the top panel (as this motherboard has no heatsink in the SoC VRM so wanted intake directly over them). My higher priority is for reduced / stable temps at idle to low-load, trying to have as quiet as possible, without causing the fans to ramp from light loads like heavy web pages or opening apps.
The main problem these days is always the hot air exhausting from GPU in a big ball in roughly the middle of the case and near CPU. If we could have cases with quite heavy ducting around GPU to separate it's intake and exhaust air route off the rest of the case, we would be golden, and some guy on youtube demonstrated it.
After years of trying different cases I've ended up with a full mesh case. Tower cpu cooler and full 4 pull 3 push fan setup. Best airflow, temps and dust control I've achieved. For now my money on full mesh cases.
Thanks for sharing your findings!! It's true, sometimes our meddling with the fans worsen things. lol I have a matx with slightly smaller than medium tower case, 2x120mm fan front and 1x90mm fan rear. After some testing, decided to downclock my cpu (Ryzen 5600G) and old gpu RX580 8GB, and the two run at relatively cool temps of 37degC/40degC idle, and 45degC/55degC full load ... with both front fans turned off. And I am in Singapore, avg temps 27degC - 33degC. Dec 2024 recorded 36degC tops!!
With how easy, fast and efficient it is to do undervolting... and you don't have to fight with a lot of fans, connectors and screws, not to mention the constant assembly and disassembly of PC components...
I personally have 2 large intake fans at the front, and 3 smaller intake fans at the bottom, with 2 fans on the CPU cooler and 1 fan on the rear serving as exhaust. No fans at the top. The idea is the air coming from the bottom exclusively cools the GPU, while the air coming in from the 2 large intakes is pulled into the cooler + rear exhaust fan. I run all of these fans on "silent" configurations and rarely, if ever, hit temps nearing 90C+ on any of my components even during specific stress testing. I'm surprised this is the one configuration you didn't test. I'd really like to see some specific numbers about it.
okay so i click i watch, and i suspect some creator with around 500k subs, and then i see less than 2k, and such good content, keep up good work and nice ideas like this video
given there are 3 intake front mount , 1/2/3 intake bottom mount depending on case ,1 rear exhaust , you should try : 1. one intake top mount close to the front panel , one exhaust top mount just above the cpu cooler 2. two intake top mount , one exhaust top mount close to the rear exhaust fan 3. one intake top mount close to the front panel , two exhaust top mount all should be done with 2 fans attached to the cpu heatsink given the heatsink is dual tower , but in your case its single tower but would still recommend using 2 fans blowing the air in the SAME direction which ideally would be towards the rear end ( with ofc the case in the normal layout and not in inverted layout )
So in a regular atx case like the nzxt h7 flow 3 front intake, 1 rear and 1 top exhaust is still the go to right? This is with an air cooler on the cpu
What steps did you take to control the temperature of the room? I find it quite hard to believe that pointing a large fan at the PC with the side panel off made the temperatures worse. You really need a thermometer measuring ambient temperature if you don't have one already. I still appreciate the effort you put in to testing and I enjoyed the video.
its worse because when you have air blasting with a lot of force into a enclosed space the air 'splashes' on the motherboard and rebounds causing a lot of turbulence killing the airflow. But then he did the test completely wrong because if youre going to use a large room fan you would get one with a motor that doesnt stick out that much and you would have it flipped the other way to draw air out of the case so it is pulling in cooler air from all the other holes on all sides of the case simultaneously.
I built the same case for a friend. Intake: 2x bottom, 1x rear, 1x top rear, 2x lower front. Exhaust: 2x top, 1x upper front. All 140mm, normal board orientation. Can you test this setup and post temps?
He said that is not the best configuration. He said that your bast off creating a low pressure effect inside the case. Meaning you need to have more pointing outside the case then in.
On 8:00 text on the right is incorrect.
It must be CPU - 80.9 and GPU - 69.1
I mixed it up with the same scheme, but with a fan beneath the GPU. You can see them next to each other at 8:29 in the middle.
However, this doesn't affect the essence of what was said, because the text was written based on the correct data, and the error occurred during editing.

Рома виходить на новий рівень?)
What if you programmed the fans to “inhale and exhale” on a loop? Breathing pc lmao might actually be good airflow 😅 and it would be funny to see.
i would love to see that
watch DIY Perks, he made a breathing PC
Your lungs expand to breathe in. Lmk when your PC case can do that 😆
@ two words “soft case” nah but I know lol
@@cosmic_gate476 i honestly laughed at the image of a pc actually breathing like a lung
These aren't stupid , but very smart and useful experiments. Thanks for your time dedicated to it.
while we are at it why don't we remove the case
caseless builds be like
Because then you won't have any airflow and in turn would have bad temps.
@@rene837 nope, actually it's cooler.
@@LucFireCraft He never intsalled the fans in the correct order. Front to back and bottom to top. If you install the fans in the correct way the temps are way better than without or his "Base" scenario with just one fan in the back.

A summary/reminder at the end would have been golden. What was the best fan setup with all panels on in the "right side up"(non-upside down) configuration?

Negative pressure to draw air in using top and rear exhaust.

Увидел превью и уж хотел кинуть жалобу за кражу ролика, а это просто Рома тренирует свой английский и предает свои эксперименты более масштабной огласке)
Так держать, удачи в развитии и этого канала!
Так же)
It's also important to think about dust intake with negative internal pressure. Its better to have a slight possitive pressure to make sure the air is getting in through the filters of the fans
i like the speed of the video, great editing
Not gonna lie, these are the kinds of questions I wanted answered. I built a PC that I designed to cool a 65W i7 passively with the NH-P1, but I decided it was such a neat build that I wanted it to be my main PC. So now I have intake fans for the GPU and to try to maintain positive pressure to try to reduce dust buildup in the full-mesh case, and my one exhaust fan only comes on when things are getting toasty (mobo above 40C and/or CPU/GPU at pretty high utilization). And yeah, I'm getting similar results to some of these where my CPU thermals are a little worse when the GPU fans and intake fans near the GPU are active. But my case is really well ventilated, so it only goes up by a few degrees.
And I always thought the "hot air rises" arguments for fan placement were silly because fans necessarily introduce turbulence.
0:18. Ah yes the gaming coolinglol
Some forgotten knowledge from years ago, PC's came with CPU Fan Duct, which dramatically reduced the overall system temperature, but mind you, GPU's at the time were pretty low power and even some of them had a passive cooler or a tiny fan... *Coughs heavily in Nvidia MX440*.
Very good videos. Keep up the good work. Love from Scotland
One of the best configurations i have found so far for an (old) case that does not have any openings at the top is 2 good 140mm (covered by lite mesh) and 1 120mm exhaust fan and removing ALL obstructions from the back. This walks very well cooling pretty high temp hardware 12400h (stock fan!) + 3080ti, on the cheap. One 140mm fan had a place for it, the other one i had to jurry-rig on my own in place of the old cd and floppy trays. The result is very quiet with fans configured to run up to 80% speed, moves a lot of air through the case and the exhaust feels burning hot to the hand. First tried without removing the back covers, it worked but it felt that there is too much pressure in the case, the situation improved drastically with every additional cover i removed. The exhaust fan is there is there basically to circulate the air then the pc is idle or at a very low load. The fans are old Noiseblocker NB-eLoop that have a very unique shape and have some unique properties, like a very focused current of air. They are pointed directly at the cpu and gpu, and are configured to ramp up with gpu and cpu tems respectively. Unexpectedly, the fan pointed at the shitty stock intel cooler improves the cpu temps insanely, it drops like 10-15 degrees when the cpu focused 140 fan ramps up and is practically silent if its rmp does not go over 85% of max rpm. I call this my windtunnel setup. The fan curves are set up via the FanControl software, it also works well for limiting the speed of the stock cpu cooler to make it no go into its whiny and low top rpms. Dont remember the exact temps but the cpu is usually under 70, and gpu under 85, they could go much lower if I allow the fans to go to 100, but this is the sweetspot for cool and quiet for me.
(This was done to save money, i wanted to reuse as much of my older system as possible, and the only cooling parts i purchased were the two 140mm fans fro 15$ each)
Hi, Roma. Idk how I found your TH-cam channel, but I like it.
In my configuration, I have a 360 mm AIO on top, a 120 mm exhaust at the back, and a 140 mm intake at the front. The question is whether another 140 mm at the front will improve the cooling situation.
the four fan test you need to include having the top right blowing in and the top two right blowing in, they blow cold air directly into the CPU intake
Very good video! I would have loved if you mentioned dust accumulation with possitive pressure and negative pressure configurations not to forget dust filtered intake vs unfiltered intake, etc. because i still believe dust filtered possitive pressure configuration is the best one overall.. :)
I know this isn't ment to be a serious video, but for those who want the correct setup;
The fans should blow in the same direction, i.e. front to back and bottom to top. No fans should blow against another
Keep the intakes together (front and bottom)
and all the exhausts together (rear and top)
Have filters on the intakes and at least one less exhaust fan to help keep dust out
Edit; typos
So for example 3 front for intake, one in the back for exhaust and one in top for exhaust so that way you have one less
@tarta5844 isn't neutral pressure the best? 3 intakes front and then 1 rear exhaust and 2 top exhausts?
@@Clashy69 A slight positive pressure pushes air out the gaps in the case, helping to keep dust out,
You could have a 3+3 setup, but have a 240 radiator as exhausts, and the restriction from the rad would create positive pressure
@@AndroidBeacshire what if u just have normal 120 fans? is what i said still good or is it better to just have 3 front intakes 1 rear exhaust and then only 1 top exhaust?
@@Clashy69 A 240mm AIO radiator has two 120mm fans.
But if you have 3 intakes at the front, one or two exhaust fans at the back/top will be fine
I got XT VIEW case. Top 3x intake, rear 1x intake, bottom x1[GPU extra] intake, 2x back side exhaust. Custom fan curves on all, CPU tower fan to pull. No thermal issues without custom fan curves, however fans do ramp when gaming custom fan curve by design. G/HTPC sofa experience so fan noise doesn't bother.
SO an open test bench wins....well yeah but as soon as I spill my beverage my PC is cooked lol
Finally I've been waiting for a vid like this
I love playing with fans! I have a Tower 900, and I've been messing around with fan configurations a while. I currently have a separator between the gpu and cpu. Gpu side has intake on top and bottom (going to do more testing with that soon). Cpu side is top intake, and three exhaust fans blowing out the bottom.
Top intake is working quite well. I get fresh air directed through a shroud to the cpu cooler, and it doesn't go over 70 at max load. 8086k delidded at 5.3 ghz
Loved your video saved me from doing this experiment myself.
Хорошо, что завел английский канал, респект
That's why pc layout of ''tower'' cases haven't changed since late 80's / early 90's because, it just works, what changed was addition of bigger fans, bigger heatsinks on components, removed 5.25'' or 3.5'' drive caddies and other features but, foundation itself - didn't
Nice fun and informative video to watch!
Did i miss it or there was no test on having 3-4 intake fans to have a positive pressure one?
Congratulations, awesome work !
used different fan layouts in most of the pcs Ive built. Just more fun that way. I've found them effective enough, my main rig uses 8 intake fans and one exhaust, nevery have issues with throttling from a 5950x and 3090. that said I agree with you that "out of the case" thinking usually doesn't work as initially imagined
Thank you for the research and testing!
Just toss the CPU in the toilet water tank. EASY permanent cooling solution.
0:20 no one beat cheap 220V cooler :p
Actually amazing and very well done video
I recently added a fan as exhaust through the spare PCI slots (my aftermarket GPU cooler JUST permits one to fit one between it and the slot covers), helped a bit (without dedicated testing), likely by getting more intake to reach more of the GPU cooler fans and keeping more of the GPU exhaust away from the CPU cooler. Though I also added intake and exhaust fans to the top panel (as this motherboard has no heatsink in the SoC VRM so wanted intake directly over them).
My higher priority is for reduced / stable temps at idle to low-load, trying to have as quiet as possible, without causing the fans to ramp from light loads like heavy web pages or opening apps.
The main problem these days is always the hot air exhausting from GPU in a big ball in roughly the middle of the case and near CPU. If we could have cases with quite heavy ducting around GPU to separate it's intake and exhaust air route off the rest of the case, we would be golden, and some guy on youtube demonstrated it.
After years of trying different cases I've ended up with a full mesh case. Tower cpu cooler and full 4 pull 3 push fan setup. Best airflow, temps and dust control I've achieved. For now my money on full mesh cases.
Can you give some examples please?
Thanks for sharing your findings!! It's true, sometimes our meddling with the fans worsen things. lol
I have a matx with slightly smaller than medium tower case, 2x120mm fan front and 1x90mm fan rear. After some testing, decided to downclock my cpu (Ryzen 5600G) and old gpu RX580 8GB, and the two run at relatively cool temps of 37degC/40degC idle, and 45degC/55degC full load ... with both front fans turned off.
And I am in Singapore, avg temps 27degC - 33degC. Dec 2024 recorded 36degC tops!!
All air in, this guy Antec LANBOY AIRS!
With how easy, fast and efficient it is to do undervolting... and you don't have to fight with a lot of fans, connectors and screws, not to mention the constant assembly and disassembly of PC components...
I personally have 2 large intake fans at the front, and 3 smaller intake fans at the bottom, with 2 fans on the CPU cooler and 1 fan on the rear serving as exhaust. No fans at the top. The idea is the air coming from the bottom exclusively cools the GPU, while the air coming in from the 2 large intakes is pulled into the cooler + rear exhaust fan. I run all of these fans on "silent" configurations and rarely, if ever, hit temps nearing 90C+ on any of my components even during specific stress testing. I'm surprised this is the one configuration you didn't test. I'd really like to see some specific numbers about it.
i have very similiar setup, but i dont have any exhaust fans. I added one and it had 0 effect on the temps 🤔

I grew up with no air conditioning, we cooled the computer with a floor fan.
okay so i click i watch, and i suspect some creator with around 500k subs, and then i see less than 2k, and such good content, keep up good work and nice ideas like this video
given there are 3 intake front mount , 1/2/3 intake bottom mount depending on case ,1 rear exhaust , you should try :
1. one intake top mount close to the front panel , one exhaust top mount just above the cpu cooler
2. two intake top mount , one exhaust top mount close to the rear exhaust fan
3. one intake top mount close to the front panel , two exhaust top mount
all should be done with 2 fans attached to the cpu heatsink given the heatsink is dual tower , but in your case its single tower but would still recommend using 2 fans blowing the air in the SAME direction which ideally would be towards the rear end ( with ofc the case in the normal layout and not in inverted layout )
very underrated content, keep it up!
good presentation quality! thank you for your research
the accent is strong with this one,also bratushka i can see the horrendous gpu sag😭😭
So in a regular atx case like the nzxt h7 flow 3 front intake, 1 rear and 1 top exhaust is still the go to right? This is with an air cooler on the cpu
What steps did you take to control the temperature of the room? I find it quite hard to believe that pointing a large fan at the PC with the side panel off made the temperatures worse. You really need a thermometer measuring ambient temperature if you don't have one already. I still appreciate the effort you put in to testing and I enjoyed the video.
its worse because when you have air blasting with a lot of force into a enclosed space the air 'splashes' on the motherboard and rebounds causing a lot of turbulence killing the airflow. But then he did the test completely wrong because if youre going to use a large room fan you would get one with a motor that doesnt stick out that much and you would have it flipped the other way to draw air out of the case so it is pulling in cooler air from all the other holes on all sides of the case simultaneously.
This is perfect! But I still wonder about all fans on intake and removed side panel...
honestly i think the air would just escape? since it follows path of least resistance.
peak content right here, thank you rozor
I built the same case for a friend. Intake: 2x bottom, 1x rear, 1x top rear, 2x lower front. Exhaust: 2x top, 1x upper front. All 140mm, normal board orientation. Can you test this setup and post temps?
2-3 intake fans in the front and 1 exhaust fan in the rear is all you need.
He said that is not the best configuration. He said that your bast off creating a low pressure effect inside the case. Meaning you need to have more pointing outside the case then in.
I never thought i'd have Viktor from Arcane teach me about airflow in a desktop tower.
