So 2 on the front (intake), 1 top back(exhaust), 2 side panel (intake). It's not very open to airflow and needs more that just 2 fans to aerate properly. I definitely recommend using top fans as intake. Cut a piece of paper towel about one inch wide and six inches long. The difference there is that I have formal education and hands on experience with physics, while they are just computer guys. It has 3 x 180mm intake fans and 1 x 120mm exhaust fan so in terms of positive pressure, it has plenty. I am getting a 400R tomorrow and have been looking for suggestions on airlfow. [–]vcarl 1 point2 points3 points 9 years ago (0 children). Your floor or carpet can simply block the airflow of your pc, especially if your power supply is placed in the bottom part of your pc and if your case only supports 1-2 fan slots. Maybe without the rear fan. The red arrows represent fast, hot air. No submissions about memes, jokes, meta, or hypothetical / dream builds. 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. Therefore, top fans do not always have to be exhaust, and can even be detrimental to airflow in some cases. You will have a "negative pressure" system if more of those fans are exhaust than intake. That way, no dust gets inside your PC. Has anyone got a guide for getting the air flow right. This means that equivalent fans on intake (with a dust filter, thus lower CFM) and exhaust will give you negative pressure because your intake fan has to deal with the filter while the exhaust fan does not. This setup assumes there is a side panel fan and there are two top fans, in addition to the ones pictured. This page has a few good diagrams that will help demonstrate the different setups. I don't know if you saw this, but it's pretty much what you're talking about. pretty much, just the top-rear fan should be an exhaust instead. Have you got any advice about when to cover grills? In a static system, yes. Exhaust fans don't need covers. In the 780t (and most similar cases with two front, two top and one rear fan) I would run the front and rear as intakes and the top as exhaust, but to do that you would really want to have a dust filter for the rear fan, as you want to have a dust filter on any air intake. Only on intake. As you may be able to tell there is some dust there, albeit pronounced by the flash of the camera. Would you say this diagram is ideal, if instead of 2 optional fans behind the HDDs they be installed on the side panel? Additionally, warm air is easier to move than cool air. Whatever configuration will accomplish this for you is what you should use. This will work as a great dust filter and you can clean it by running it through the wash or vacuuming it. To avoid any confusions, we are only going to look at the 5 best airflow pc cases available in the market. Meaning more intake fans than exhaust. (3D rendering). [–]Grumpy007 0 points1 point2 points 9 years ago (4 children). [–]vcarl 1 point2 points3 points 9 years ago (2 children). 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 … For dust do this. In the pictured setup, the top left fan is exhaust while the top right fan is intake. Choosing a good cooler for your CPU and doing a good job with your thermal paste is 1000x more important. I agree, except I would add that a good side panel fan will help also. [–]ccampo[S] 0 points1 point2 points 9 years ago (0 children). use the following search parameters to narrow your results: Please keep in mind that we are here to help you build a computer, not to build it for you. Conversely, a negative pressure system does just the opposite as a positive pressure system. Trying to get the best possible airflow for the system, I have the CoolerMaster MasterLiquid Lite 240 attached in the front with a push and pull airflow going (4 Fans attached) acting as Exhaust 2 Fans on top acting as exhaust, And rear as exhuast only one intake which is the bottom beside the PSU going full power. Rendered by PID 842 on r2-app-0c86560e31d3c7463 at 2021-01-07 22:17:30.911830+00:00 running 22f414d country code: US. 1 fan in the back is good, add 1 fan in the front and it's better. [–][deleted] -3 points-2 points-1 points 9 years ago (0 children). This provides positive pressure to reduce the dust taken in through cracks and non-fan vents in the chassis. I agree that that is a fantastic case for airflow, as everything OS perfectly laminar and obstruction free. 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. The resulting air is "thinner", and less dense, and therefore requires less energy to move. For some fixed, permeable volume, there will be less particles present if the air is hot rather than cool. having 8 small 110mm fans at 10% speed instead of 2 120-140mm fans operating at 100%. Here's my PC. which comes with amazing features you’ve never heard before. Remember your basic fluid dynamics to determine the direction of the airflow. There are dust filters on each of the intake fans and one over the PSU intake grill so the case is always dust free. ". Positive and Negative Pressures - What Are They? Because of this, you should configure your system based off how powerful your fans are and also the layout of your case. The blue arrows represent fast, cool air. High airflow computer cases keep the temperature of your internal components lower compared to other cases with a solid front panel or tempered glass front panel. How to check if fans are intake or exhaust? However, if you have multiple fans directing the direction of airflow, as you do in a PC, then the heat will go in whichever direction you push it. No Comments on 7 Best PC cases for Airflow in 2020 Posted in PC Components By pc Posted on 2020-05-08 2020-05-20. [–]Ender11 0 points1 point2 points 9 years ago (1 child). Building a custom PC is a delicate balancing act. The theory behind this is that having more fans (or more powerful fans) blowing air in creates a positive pressure gradient between the inside of the case and its surroundings. I recently dusted my pc and it was pretty damn dusty. How To Build A Gaming PC: Step-By-Step Guide (2020) Putting together a gaming PC build can be an intimidating process, but it doesn't have to be … A Brief Overview of the Physics of Airflow (for dummies). [–]ccampo[S] 1 point2 points3 points 9 years ago (0 children). It’s on version 3.0 so I’m not sure if it has more features/ big fixes. The pink arrows represent slow, hot air. Cooler Master H500M – View on Amazon. I drew out a positive pressure flow diagram to further demonstrate what is going on. Speaking of dust, you want to make sure that your computer remains as dust free as possible. The intake and top exhaust are speed controlled (switches by the 5.25 bay). Press question mark to learn the rest of the keyboard shortcuts. All of our components are housed in the Corsair 4000D Airflow edition case. I have the front three fans of my H440 set to intake with the rear fan and two fans on my radiator set up to exhaust. Getting the air flow right is an imprecise science at best. 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. Do you ever lean next to the box fan and go, "computer...I am your father"? These specs make these hands down the best PC cooling fans on the market, however, there is a catch. To reduce dust in the case, ensure that the air going into the case first passes through a filter. Sadly there are only so many hours I have to piss away at work. I have a mid ATX case with two graphics cards that are producing a lot of heat. [–][deleted] 2 points3 points4 points 9 years ago (1 child). [–]funktion 1 point2 points3 points 9 years ago (1 child). Is a lot quieter plus it looks better with lighting. I wasn't sure if my case was currently positive or negative flow so I did a little test. The air inside will be sucked out, and therefore the air inside will be less dense than outside. 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). I currently don't have a fan mounted on the side panel (when I get a second GPU I will definitely add a side fan) and I wondered if that opening was pushing or pulling air. A Brief Overview of the Physics of Airflow (for dummies) Airflow, or more specifically fluid flow, is governed by the laws of fluid dynamics, which are simply just restatements of physical principles such as conservation of energy and Newton's laws, applied to fluids.Air, as you should know, is a fluid, and its movement is therefore governed by the laws of fluid dynamics. 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. This post is so I remember to come back and read this. Checking the Flow of Air exiting your computer is not a difficult thing to do. With the mesh front, LANCOOL II MESH making great airflow in the chasis, Packing three ARGB PWM 120mm fans effectively cooling the component in user's PC build and able to control by the botton on the I/O port.
