Looks like you're using new Reddit on an old browser. Do you ever lean next to the box fan and go, "computer...I am your father"? The positive aspect of this setup is that the system will more quickly cycle out hot air. There are debates about whether positive pressure (more intake = more cool air in and less dust) or negative pressure (more exhaust = more hot air leaving case) is better. They are also various spacious and are best for building a high-performance PC. I definitely recommend using top fans as intake. Here's my PC. I believe this is mostly due to people not quite understanding the science and reasoning behind it all. Yea, figured it deserved reaching a wider audience, as I have recently seen a bunch of questions on here regarding cooling and airflow, etc.. [â]sime 0 points1 point2 points 9 years ago (1 child). This method will establish a wind tunnel-like effect. This is because warm air is less dense than cool air, for some fixed volume. Best Airflow Cases for Gaming and Work PC. Otherwise, the cases airflow isn’t very good and the cooling of the components isn’t efficient. An intake fan’s airflow decreases fairly linearly as pressure increases. I don't know if you saw this, but it's pretty much what you're talking about. If possible, attach the CPU fan so, that the hot air is flowing towards the case fan, that is pushing the air out of the case. Larger fans tend to have higher CFM ratings, and anything obstructing a fan will lower it's CFM. Edit: kinda like this image, not sure that's the same case, but you get the idea. GPUs are a lot hotter than CPUs and they will benefit a lot more from a side fan; so much that even if a bit of their hot air gets to the CPU, it is still worth it. This will work as a great dust filter and you can clean it by running it through the wash or vacuuming it. Airflow is still important however; I upgraded my case from a Rosewill Blackbone to a Corsair 400R and even with the same side panel fans (2x 12 cm fans), my graphics card temperatures were nearly 10 C lower. [â]ccampo[S] 2 points3 points4 points 9 years ago (1 child). Then, we scored units for build quality, ease of installation, phone fit, mount security, whether or not a modification to the case or phone are required, and the tendency to block outward visibility. It all depends on the setup. The physics behind all of this is quite fundamental, and worth researching if you are interested, but what is important to know right now is that air moves from higher to lower pressures. I would, yes. Great read. It's not very open to airflow and needs more that just 2 fans to aerate properly. The most important thing is that your system is constantly supplied with cool, fresh, dust free air. If you have a good cpu cooler and airflow design, the CPU will be supplied with plenty of cool air and the little bit of warm air that hits it will be negligible. [â][deleted] -3 points-2 points-1 points 9 years ago (0 children). I wouldn't say 1000x because I don't spit out numbers unless I can substantiate them. Is a lot quieter plus it looks better with lighting. Meaning more intake fans than exhaust. A Fitting Choice: Combining innovative cable management, concentrated airflow, and proven Corsair build quality, choose the 4000D for an immaculate high-performance PC. After Jayz and GN's recent vids I decided to grab a surplus Aeron. Yeah, you've definitely got the theoretical aspect of it down, while they have experimental data. They were right. Hardware Guides. Planning on building a computer but need some advice? I have the Corsair 600T and I can add more fans on the side. It is a great idea if your air is moisture free. turn the front top exhaust into an intake and yer golden. I've now bought a pc case with great dust filters (Corsair 780T) and some liquid cooling but there are still 4-6 fans to put in the case. Central to this is the debate between "negative pressure" (more air exhaust than intake) and "positive pressure" (more air intake than exhaust) systems, and which configuration provides the best cooling for your PC and its individual components. By the Bernoulli principle and simple physics, the fresh air will tend to push pockets of older air out of the case (through random holes and crevices like the 5.25" bays and the expansion slots) as they move towards the lower pressure outside. Dust accumulation is a major hazard to electronics, as it is an insulator and can clog up exhaust ports. Conversely, a negative pressure system does just the opposite as a positive pressure system. As an FYI on my level for this, I hear a lot about intake and exhaust but am only guessing when I actually screw the fan in. There are dust filters on each of the intake fans and one over the PSU intake grill so the case is always dust free. [â]knullcon 0 points1 point2 points 9 years ago (2 children). would that be enough? I have one intake fan on the front (12cm), one exhaust fan (12cm) on the rear, one exhaust fan (14cm) on the top, and one exhaust on the PSU (12cm, mounted on the bottom). This can sometimes happen with smaller cases fitting for mini-ITX motherboards, but even some larger cases have designs which are more favourable to certain GPU and cooler design… I agree that that is a fantastic case for airflow, as everything OS perfectly laminar and obstruction free. Unless you have performed comparisons with the proper controls, you shouldn't grossly underestimate airflow. Have you got any advice about when to cover grills? Posted by Reddit user u/sourcekappie here. Has anyone got a guide for getting the air flow right. If you can create a strong flow over your CPU using an exhaust fan, do that. Just because you don’t have a super-high-end system doesn’t mean you should forego doing cable management. 9 drive mounting space and supports 384mm maximum GPU length and 176mm maximum hight clearence.Sollution for the cable management with double tempered glass to view the interior. It includes a USB3 port, USB Type-C port, a mesh front panel for excellent airflow, and a number of cable management holes and tie-offs to help your build look cleaner. I held a piece of paper up to it and it mildly stuck to the port indicating that it is pulling air which means my case currently has negative pressure. If you have dust filters on your intake fans, your system should remain virtually dust free, since this scenario only allows air to be brought in through the fan emplacements. (3D rendering). Also note that filters only need to be placed on intake fans. 1 fan in the back is good, add 1 fan in the front and it's better. I just leave the side of my case off and occasionally point a box fan into it. The radiator support is superb, with up to a 360/280 mm unit at the front, 420/360 mm at the top and even a 280/240 mm at the bottom. The blue arrows represent fast, cool air. Yeah...me neither. [â]Grumpy007 0 points1 point2 points 9 years ago (0 children), [â][deleted] 2 points3 points4 points 9 years ago (0 children). Depending on the strength of the fans, this configuration may even be beneficial, but circulation cells should be avoided if possible. Diameter: 120 mm Airflow: 53 CFM Noise: 24.1 dBA LEDs: None Connector: 3-pin Dimensions: 4.7" x 4.7" x 1" The budget fan business is pretty competitive – when you can get a … pretty much, just the top-rear fan should be an exhaust instead. For dust do this. Central to fluid dynamics is Bernoulli's principle, which simply states that if the pressure (or potential energy) of a fluid decreases, its speed increases, and vice versa (which is simply a restatement of conservation of energy and Newton's second law, the more universal physical laws). Getting the air flow right is an imprecise science at best. Despite the huge number of discussions, there does not seem to be any agreement on which is the best. We’re talking about physics, thermodynamics, all sorts of fun stuff. As an added step, I would filter the fan if you make it intake. The best bet is to draw out your airflow diagram and see what will provide the most wind-tunnel like effect while minimizing dust intake. Last Updated: 15th April 2015 - (Rewording of Introduction) This is a step by step, illustrated guide on how to put together your parts, complete with detailed photography and commentary; it can be supplemented with a video tutorial such as Newegg’s ‘How to Build a Computer’ series found here.. I drew out a positive pressure flow diagram to further demonstrate what is going on. Cooler Master H500M – View on Amazon. As far as negative pressure systems go, you are basically creating a vacuum cleaner. In my case, a positive pressure system is the most beneficial.

Go and buy some women's tights from Target or something (get the cheapest ones and the largest size) and stretch them across the fan until they are nearly transparent (a very tight stretch). [â]vcarl 1 point2 points3 points 9 years ago (2 children). If you are searching for a new chassis for all that futuristic tech you’ve just bought, there are a few things to consider when it comes to airflow optimising. It just seem weird to me to have intakes from 2 opposite sides of the case, but maybe the air"flow" isn't really affected, I dunno. Also, the rear of this cubby that the PC doesn't go all the way down to the bottom; only about 1/4 of the way down the PC, you just can't tell from the picture. Of course, dust filters should be over your intake fans. High airflow and static pressure fans blow air through your PC, but they do it in different ways. Checking the Flow of Air exiting your computer is not a difficult thing to do. There is a spot on the side for another fan, I just haven't installed one to keep noise down. Apologies, I did try looking (as it sounds like a basic question) but has anyone got a guide to getting the airflow right on cases? This setup assumes there is a side panel fan and there are two top fans, in addition to the ones pictured. [â]Azurphax 0 points1 point2 points 9 years ago (1 child), This really brings me back... about two weeks, [â]ccampo[S] 4 points5 points6 points 9 years ago (0 children). Air, as you should know, is a fluid, and its movement is therefore governed by the laws of fluid dynamics. If you tilt them at an angle, the water will fall out of the cup quite quickly while the syrup will crawl along. This guide will help you find the best PC case for your needs. This PC build guide puts together the best components available to make you a rock-solid high-end gaming PC that should keep you happy for a couple of years. [â]ccampo[S] 0 points1 point2 points 9 years ago (0 children). No submissions about memes, jokes, meta, or hypothetical / dream builds. All the above assumes that all fans are of identical performance, and that you are using a dual fan air cooler in the top. No self-promotion, advertising or surveys, No selling, trading or requests for valuation, No excessive posting (more than one submission in 24 hours), No intentionally harmful, misleading or joke advice. The pink arrows represent slow, hot air. Now open the side of your computer as you would if you were servicing the internal parts. The difference there is that I have formal education and hands on experience with physics, while they are just computer guys. Airflow is important in choosing the best PC case, especially when it comes to high-end components in tight spaces. did it not say thats bad because it blow the heat from the gpu onto the cpu ? The parts holding the motor centered should be on the exhausting side. Idle temps are around 36Â° when totally clean. Hopefully this helps when configuring the airflow of your system! In the case of a PC, the syrup is the cold air, while the water is the warm air! Building a modern desktop PC is surprisingly easy, thanks to modular parts and a lot of solid engineering. If you aren't careful, it can condense on your computer and it's parts, and that is a bad thing. But thanks for any suggestions :), [â]Calvus 0 points1 point2 points 9 years ago (0 children). Saving some money here and there on things like the case and the fans can lead to more room in your budget for a better GPU or CPU. So 2 on the front (intake), 1 top back(exhaust), 2 side panel (intake). [â]Grumpy007 0 points1 point2 points 9 years ago (2 children). You want to keep in mind whether any components are going to be stifled for air by any obstructions. Yea, they just released that the other day. Understanding case airflow and the physics behind it (xpost from r/gamingpc), This video demonstrates "positive pressure" airflow, This page has a few good diagrams that will help demonstrate the different setups, No submissions about hardware news, rumors, or reviews, No submissions about sales, deals or unauthorized giveaways, No submissions about retailer or customer service experiences, No submission titles that are all-caps, clickbait, PSAs, or pro-tips. For PC - Hardware Discussion on the PC, a GameFAQs message board topic titled "Guide to airflow? ... High Airflow RGB LED Case Fan for PC Cases, CPU Coolers,Radiators System,6-Pack，SR12-06-6 is the suitable for you. having 8 small 110mm fans at 10% speed instead of 2 120-140mm fans operating at 100%. and advice on how to improve it? Optimal results should be intake fans on the front of the case, the sides, and the bottom (if you have a case like that). That way, no dust gets inside your PC. These specs make these hands down the best PC cooling fans on the market, however, there is a catch. That being said, number of fans is not the most important part of that, CFM is. Remember your basic fluid dynamics to determine the direction of the airflow. For some fixed, permeable volume, there will be less particles present if the air is hot rather than cool. Exhaust fans should be on top and in the back. This will allow air to flow freely through the case fan o… It will most likely be this way for all systems. Most of the talk is about what is the best fan configuration, and everybody seems to have their own opinion without knowing any of the science behind it. I would actually close them if I had any open meshes, mainly to reduce noise. Most fans blow exhaust away from the open sides. If you have a top fan as intake, your CPU has even more fresh cool air, and the side fan is nothing to worry about. ". New comments cannot be posted and votes cannot be cast. On the other hand, if your case doesn’t provide you with proper airflow then you could damage your parts and a lackluster I/O can make using your rig a pain. Closed will allow your case to sustain more pressure, open will allow more places for air to come in/seep out. Top 10 Best Airflow Case Buyer’s Guide 2020.
