@jacekmakesyep. The cases with airflow like we have today weren't existent in the 90s. You were lucky if you had even a small side panel fan port. Cases were coffins with solid front, top, and bottom panels, PSUs at the top that had nowhere to really breathe except their exhaust... So yep, we would fabricate our own aftermarket case components or cut new airflow points. Even graphics cards in their early days had poor heatsinks and no active cooling (looking at cards like the Voodoo series, etc, lol).

Just to add: negative pressure is mostly beneficial to crammed components like in a mini ITX system. You want the heat to get out asap and not stay inside especially if there is no space. There is also the nzxt h500 with an almost restrictive front panel which benefits from negative air pressure. You can also force cases to have positive pressure even if there are more exhaust fans than intake. Just decrease the rpm of all exhaust fans and increase the rpm of intake. Vice versa if you opt for negative pressure.

Good video but surprised you did not discuss the difference between Static Pressure and Air Flow on fan choice. For general case fans you want to focus more on air flow than static pressure. These fans are about creating air movement. When you want to focus on pressure is when the fan is against a cooler or radiator and you need to overcome the air flow restrictions these create.

what you are referring to as "air flow" is called CFM "Cubic feet per minute". Many new builders just buy fans that look cool or are RGB, always look for the Highest CFM with the lowest DB value

short version, possitive preassure good, negative preassure bad (not in all cases), 1 more intake then exhaust and you should be fine 3 fans is minimum, 5 is good best balance, 7+ is Enthusiast dont make air do sharp turns make it as straight as possible
@ThePCExpertAmateur8 ай бұрын
Very good, but you may not be aware that there's more to it than LxWxD and fan rotation. There are a small number of fans that actually use the convex side of the fan to push air, like the Geometric Future Squama. There are fans that have the blades with the *convex* side opposite where it is normally but STILL move air in the expected direction because they are actually designed to push air towards those arms that connect the frame to the hub, and there are reverse fans, of which I've seen both combinations. Also, even now, there are a significant number of fans that do not show direction of flow and rotation, or it's located in a hard-to see-location. So, in order to determine direction of flow and rotation, you have to look at the blades - for most fans the convex side is the BACK and the other side is pushing the air through. If, however, the back (convex) side is modified with a pattern that is not on the other side, it may be that the convex side is pushing the air instead of the concave side. 99% of the time, you won't see this and can rely on concave being the push side and, thus, whichever direction the blades are scooped in (concave) also indicates the direction of rotation. I wish you had been explicit about what the problems are with negative pressure: dust will build on on the inside of dust filters, on heatsinks and radiators, among many other places, more rapidly (depending on the room), which will require that cleanings (with a decent speciaiized vacuum/blower) than in a positive-pressure case. Also, if you have pets, their hair and dander will be pulled in. If you have positive pressure, though, most of that will be trapped in the dust filters where air is pulled in, simplifying clean-up. I'm glad you pointed out about neutral pressure, but it would've been useful to go into more detail on the non-curve aspects of configuring the case fans. It is really hard to optimize a case to eliminate turbulence and recirculation, and sometimes a more complex fan config will do a better job. Overall, though, and considering just how many variables there are that affect airflow this was quite good!
@sc0or2 ай бұрын
Just unmount a fan behind a dust mesh/filter and you'll get an idea where is all the dust. That mesh simply does not work (obviously because dust particles is WAY smaller than a 1mm filter hole). Or rather it works in a not expected way (just shapes an air flow)

The dimensions of a fan do directly change the amount of air it pushes, but, it can also push the same amount if the pitch is changed accordingly, you need to look at the pitch, amount of blades, the change in pitch, depth, radius or diameter, and speed. And the dependant variables are the static pressure, air speed, total amount of air passing through the fan and noise.

I have three big intakes at front, one exhaust fan top of the back of the case for exhaust. Simple and gives me very good temps for both GPU and CPU. Might add another small exhaust fan at the bottom back to aid air flow along the bottom of the case (thus feeding the GPU fans with more cool air and maybe one at the rear of the top of the case. I don't need either honestly though. Sometimes keeping it simple works best. Some good advice is to use a piece of paper and see where your air is already flowing then add fans where it'll aid weaker flow. Or stress your system and feel with your hand where your case is trying to vent heat and again add where it'll help.

And so you're saying to have a single direction for airflow while J2C tested the H6 and had 3 intakes from the front right side I should say (because that's how the case is, the intakes are at the front but front right sided than a complete right side) then he also had 2 bottom intakes. There was no exhaust at the rear, he instead put 2 or 3 at the top as the exhausts then when he made the test with smoke it was pretty good how the airflow would be directed. So obviously there was 2 circulation ways with that case, what's your opinion about that airflow using his setup fans? The H6 is highly praised too by many.

The result, my Ryzen 7700 with PBO+CO with TjMax=88C, gives me close to 5.25-5.35Ghz All-core, 5.5Ghz Single core, idle = 45-50C, load max as per TjMax 88C, with AIO fans running dynamic with max set @80% and case fans max at 70%, with lower temps they get slower. Where I sit, ear level: idle/browsing/video 25-30db, full load 33-38db. Close to perfect performance/noise/cooling.

Given I have 6 intake and 4 exhaust would this be classified positive? Also in terms of tuning fans, should I also be tuning the intake fans a little faster so I have more air coming in or given that I have 6 intake and 4 exhaust already should I just leave all fans running the same rpm?

Best thermals with inverted chassis in all aluminum case. Sub 40 C on 375watt gpu

Perspiration chimney don't really matter and as I rule of thumb, calculate 50% flow through a filter or radiator and 67% flow when turning 90 degree angles.

I’ve switched to a positive air pressure strictly due to clean dust free pc case. However I’m running my a closed loop.

I bought a pc case solely because of its minimalist design and small form which was an aerocool cs111 it only has 3 fans 2 at top, 1 back it was a bad mistake because my gpu was running too hot because of bad airflow even reaching 90c and because my gpu is hot my cpu aircooler is also getting its heat and ramping the temperature even more. I had the 2 top fans on intake and 1 fan at the back exhaust and when i change all fans to negative pressure it improve my gpu temp at whopping 10 degrees less and my cpu was still hot but i change the stock cooler to a bigger one and it improve cpu temp to only 76c rather than 90c. Negative pressure works well on small cases with less airflow.

🙂 on two of my cases i have all the fans pointing inwards because they are argb fans and the case is a fishtank design, only recently some companies are starting to sell argb blades in reverse direction which i imagine with time will be more common

Honestly I just keep it simple. Air pulled in from the front (3x120mm), and one 120mm from underneath. One 120mm and one 80mm blowing it out the back. It all blows over the CPU and GPU and out the back (two more 120mm fans attached to cooler tower). I have heard people say thats a "negative pressure" build but tbh I dont know exactly what they're talking about. All my temps are more than acceptable so idk, works for me. As for telling what direction to orient fans, the back (exhaust) always has the bracket.

17:05 on that topic what I did is to make it in reverse :D. I made my case take air from the back and let it out from the front. In this case it is ugly from the outside but the temperatures dropped a lot. Almost 10 degrees with the same components. It was back in the desperate crypto mining days when I had 2 GPUs in the case constantly mining. I had one fan reversed to take cool air directly to the CPU and one under the main GPU pushing again fresh air in. Than I reversed the 3 fans on the front of the case for taking the hot air out and I am still using it that way. It is cooling the hottest parts best because the cool air enters right next to them and than it goes around the RAM, HDDs and other stuff. It is a closed case under the desk on the floor with 2 filters on the intake fans and now when I am not mining anymore all the fans are on low almost all the time. My 5900x is cooled by a Noctua NH-U12A and can't go over 65 degrees with PBO.

I have just started using the Masterbox q500L which is the cheaper version of the one you start the program with. I find it a very interesting case with masses of flexibility, quite small for its capability. It also enabled me to make the build upside down and get the IO on the right, not the left, as I look at the window, some thing I want. I normally use AIO cooling but am using air at present. The PSU hangs off the left side drawing in outside air and exhausting upwards through top 1200 fans. The 1400 bottom fans feed the air in. The case openings on left and right I have sealed off with ABS sheet. This leaves the GPU fans actually fighting the air flow but they are rarely on, as I don't play games and has not been detramental. I have 4 gen 3 and 4 nvme drives fitted and the the standard AMD cpu fan (at present). All temperature are well in control and the fan speeds are quite low and quiet. My 2tb WD black was running quite hot, as they all do, but a thermalright HR-10 2280 pro heat sink fixed that, the other 3 are fine on their own. I try with all my PC builds and case changes to create a bottom to top flow. The top exhaust usually being the AIO 1200 fans and the input being 1400 bottom fans to put more air in than out. Another thing I do to force this flow is blank off all openings in the front and rear. Despite your dire comments on air running round in circles and getting lost my method forces the air to go in a single direction It has no alternative. What goes in must get out and only the top is available. I note with the second case you have, that the 3 side fans are largely a waste of money, (looks alright though) the top one in particular is ideally placed to feed the top right exhaust fan thus losing case flow generally, including exhaust. Also when showing the smoke air flow part a lot is seen coming straight from the front inputs and venting out through the adjacent unfanned top without actually doing anything. That part of the top should be blanked off forcing the air through the case.

Glad you made this video. My current setup which I want your opinion on or anyone reading this opinion. I have a Lian Li O11D Evo RGB case and the way I have my fans set up is like so... I have 3 fans bringing in air from the side/front, 3 AIO cooler fans that are exhaust on top, 3 exhaust fans on the bottom and 1 exhaust fan in the back. Everything stays nice and cool every since I built this computer this way. Even with gaming I have good cooling with no overheating issues, but what do you think?

The video is good, but the background music is VERY loud, I believe that you should lower the db of bg music so that your voice will sound better and clearer.

Great video very informative! I currently have the King 95 pro case, 7800x3d, montech d40 (or whatever the name is lol) aircooler and a red devil 7900xtx, and have a decent fan curve going on. Highest ive seen my temps go are about 68C gpu and 72C on the cpu, results from coretemp and afterburner. Doesn anybody have any tips on how to get those temps down a little or are those decent temps?

if you are using aircooler.. remove the glass front. and better put the front mesh addons then add fans there

It would also be good to note that obstacles such as a radiator decreases the amount of air that goes in or out of the case. It's much more than just the number of fans.
