pc airflow guide reddit

Planning on building a computer but need some advice? The pink arrows represent slow, hot air. 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 … I believe this is mostly due to people not quite understanding the science and reasoning behind it all. I can't stand cleaning dust out of my system and PWM fans let me keep airflow (and therefore dust) to a minimum unless I'm really stressing it. Depending on the strength of the fans, this configuration may even be beneficial, but circulation cells should be avoided if possible. [–]ccampo[S] 2 points3 points4 points 9 years ago (1 child). Hopefully this helps when configuring the airflow of your system! I agree, except I would add that a good side panel fan will help also. Basically, a positive pressure system means that you have more air coming into your case than being exhausted out of your case. Is a lot quieter plus it looks better with lighting. The Cooler Master MasterBox Q300L TUF is a close relative of the Q300P, and they share the same chassis, and only a … The lower the impedance, the more actual airflow inside the case. 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. 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. 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. Edit: your radiator should ideally facing towards the top of the case with air coming through the radiator and exhausting towards outside air. But thanks for any suggestions :), [–]Calvus 0 points1 point2 points 9 years ago (0 children). © 2021 reddit inc. All rights reserved. Get an ad-free experience with special benefits, and directly support Reddit. Well lucky for you, I am a trained physicist, and I'm going to attempt to straighten it all out in this post. Meaning more intake fans than exhaust. Best Airflow Cases for Gaming and Work PC. Good airflow is critical; you want a good amount of space with a constant supply of fresh air. 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. (3D rendering). [–]mattattaxx 3 points4 points5 points 9 years ago (0 children), [–][deleted] 1 point2 points3 points 9 years ago (6 children), [–]ThoughtAPCPartPicker 4 points5 points6 points 9 years ago (0 children), [–]ccampo[S] 1 point2 points3 points 9 years ago (4 children), [–]drockers 1 point2 points3 points 9 years ago (1 child). The Silverstone link suggested that. I have a mid ATX case with two graphics cards that are producing a lot of heat. Best PC Airflow Cases for 2020 So Far: $60 Budget to $200 High-End By Patrick Lathan & Steve Burke Published July 17, 2020 at 9:00 am . sorry, but so I am clear, are you suggesting this fan configuration along with 2 side fans also as intakes? I definitely recommend using top fans as intake. ... High Airflow RGB LED Case Fan for PC Cases, CPU Coolers,Radiators System,6-Pack,SR12-06-6 is the suitable for you. To reduce dust in the case, ensure that the air going into the case first passes through a filter. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. [–][deleted] 2 points3 points4 points 9 years ago (1 child). It's not very open to airflow and needs more that just 2 fans to aerate properly. There’s obviously nothing fancy here… no sleeves, no sleek color scheme, no PSU shroud, etc. I wasn't sure if my case was currently positive or negative flow so I did a little test. A Fitting Choice: Combining innovative cable management, concentrated airflow, and proven Corsair build quality, choose the 4000D for an immaculate high-performance PC. You will have a "negative pressure" system if more of those fans are exhaust than intake. Has anyone got a guide for getting the air flow right. [–]ccampo[S] 1 point2 points3 points 9 years ago (0 children). Have you got any advice about when to cover grills? As far as negative pressure systems go, you are basically creating a vacuum cleaner. PC cases come in all shapes, sizes, and features—from fully loaded ATX towers to bare-bones small form factors. The positive aspect of this setup is that the system will more quickly cycle out hot air. So 2 on the front (intake), 1 top back(exhaust), 2 side panel (intake). This will allow air to flow freely through the case fan o… An intake fan’s airflow decreases fairly linearly as pressure increases. 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. Yea, they just released that the other day. More exhaust fans will create a vacuum like effect in your case. The red arrows represent fast, hot air. It is definitely reversible, just flip it (not rotate). Optimal results should be intake fans on the front of the case, the sides, and the bottom (if you have a case like that). On top of the high airflow, these fans push the air with 10.52mm H2O of static pressure, which is literally an order of magnitude more than most of the other fans on this list. This method will establish a wind tunnel-like effect. Edit: kinda like this image, not sure that's the same case, but you get the idea. 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). Top Best Airflow PC Case 2020 1. I drew out a positive pressure flow diagram to further demonstrate what is going on. The resulting air is "thinner", and less dense, and therefore requires less energy to move. Unless you have performed comparisons with the proper controls, you shouldn't grossly underestimate airflow. Putting a fan on the side panel in my PC lowered my CPU temperature by 5C. 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. Do you recommend changing my top fan to an intake to create positive pressure? 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. I know this is a exception to the rule I have a silent case, the Fractal Define R3. Consequently, since air will want to move towards the lower pressure system, outside air will seep through any nooks and crannies. 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. Speaking of dust, you want to make sure that your computer remains as dust free as possible. They are also various spacious and are best for building a high-performance PC. heh i am just showing you a pic from my pc that the airflow is totally different because there is a watercooling system on the cpu, i hope that the picture is self explanatory for all. Despite the huge number of discussions, there does not seem to be any agreement on which is the best. Beamer app (paid app) does the same thing. Hardware Guides. We have already received the Corsair Crystal 280X airflow case in this article previously, but the MasterBox Q300L TUF from Cooler Master’s Q series is also a great alternative choice from our recommendation of the best mATX airflow PC case of the micro-ATX form factor. Since you keep getting dust, you'll want positive pressure. 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. pretty much, just the top-rear fan should be an exhaust instead. /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. Maybe they saw my original post! New comments cannot be posted and votes cannot be cast. Most fans blow exhaust away from the open sides. Sadly there are only so many hours I have to piss away at work. 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. This PC is designed to deliver high performance on all of today's most popular games without being complicated to build or costing too much. You can see that this creates a convection cell which possibly recirculates warm air into the case. Building a custom PC is a delicate balancing act. In the pictured setup, the top left fan is exhaust while the top right fan is intake. Yea, figured it deserved reaching a wider audience, as I have recently seen a bunch of questions on here regarding cooling and airflow, etc.. [–]sime 0 points1 point2 points 9 years ago (1 child). Since there is more air inside the case than outside, the density of particles is greater inside, and therefore the pressure is greater inside. I literally just thinking out loud on text. oddly it says the opposite in the manual - states the fan at the top should be intake. 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. This is an example of a budget gaming PC that has very good cable management. The intake and top exhaust are speed controlled (switches by the 5.25 bay). 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. 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. Honestly, I'm not even sure the fan is reversible. which comes with amazing features you’ve never heard before. In a static system, yes. Press question mark to learn the rest of the keyboard shortcuts. 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. Now open the side of your computer as you would if you were servicing the internal parts. When Cooler Master released the airflow oriented H500P, everyone was excited because airflow oriented cases were making a … I don't know if you saw this, but it's pretty much what you're talking about. [–]pktgumby 4 points5 points6 points 9 years ago (1 child). Of course, fan dust filters help in this aspect. Dust filter wise? 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. What would be a good ratio? Clean your PC on a regular basis! The parts holding the motor centered should be on the exhausting side. The house does seem to be rather dusty, no matter how often we sweep/vacuum/mop. Temps inside this cubby and out are practically the same. This gives rise to the fact that air moves from high pressure to low pressure. You want to keep in mind whether any components are going to be stifled for air by any obstructions. Understanding case airflow and the physics behind it (xpost from r/gamingpc) (self.buildapc). 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. Without dust filters however, you will be blowing all sorts of dust onto your components. Imagine that there is an intake fan in the 5.25" drive bays in the above picture, and both top fans were exhaust. For dust do this. Whatever configuration will accomplish this for you is what you should use. Finally, the white arrows represent slow, system temperature air. So in order for a system to cool effectively, we must keep the pressure impedance on intake fans as low as possible. [–]ccampo[S] 0 points1 point2 points 9 years ago (0 children). Yeah, you've definitely got the theoretical aspect of it down, while they have experimental data. 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. 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… 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. 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). [–]Grumpy007 0 points1 point2 points 9 years ago (2 children). After years using only mac, finally realized the dream of having my own PC, Is a 850w gold psu enough for a 2080s and 2060s? The downside is that all the air seeping in through the nooks and crannies will not be dust filtered, and your system is more likely to build up dust. I have the Corsair 600T and I can add more fans on the side. It all depends on the setup. After Jayz and GN's recent vids I decided to grab a surplus Aeron. [–]Grumpy007 0 points1 point2 points 9 years ago (0 children), [–][deleted] 2 points3 points4 points 9 years ago (0 children). I would, yes. This is the place to ask! I would actually close them if I had any open meshes, mainly to reduce noise. In this case with two big cards that are hindering net air flow (two 580s) and adding a significant amount of heat to the system, air flow through the case becomes much more important. Well, in theory, a positive pressure scenario SHOULD (and the keyword here is SHOULD) work better, due to the following reasoning: in this setup, your system should pull cool air inwards through the intake fans and exhaust air out through the exhaust fans and the nooks and crannies in your case (extra vents, expansion slots, etc.). Imagine having a cup of water and cup of sludge (and pretend that it isn't sticky). They were right. Here is a pic with some badly drawn arrows: http://i.imgur.com/sQcNc.jpg. edit: Corsair confirm for performance do the opposite of above. [–]vcarl 1 point2 points3 points 9 years ago (0 children). turn the front top exhaust into an intake and yer golden. 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. I have an annoying dust allergy (allergic to life it seems) and keep getting this wrong and ending up with cases that just clog up with dust. Thanks! and join one of thousands of communities. Otherwise, all the airflow in the world won’t help much to cool down your components. The local pressure gradients however, will be decently large near each fan. Hmmm This is really interesting. It’s on version 3.0 so I’m not sure if it has more features/ big fixes. As air heats up, the air particles vibrate and move faster and spread out (the air expands; basic thermodynamics at work here). [–]knullcon 0 points1 point2 points 9 years ago (2 children). [–]ccampo[S] 10 points11 points12 points 9 years ago* (5 children). Maybe the addition of a side fan would be enough to create the positive pressure without reversing the large 200mm top fan. I can put my hand anywhere over the top of the case and I can feel all the warm air moving upwards even with the fans at a quiet 600 rpm. It will have an i5-2500K with Hyper 212+ cooler and an MSI Twin Frozr II GTX 560 Ti. There's about 4" clearance on the rear, 4-6" on the side, and maybe 6" on top. Probably doesn't mean anything. [–][deleted] -3 points-2 points-1 points 9 years ago (0 children). Do you ever lean next to the box fan and go, "computer...I am your father"? [–]Grumpy007 0 points1 point2 points 9 years ago (4 children). As you may be able to tell there is some dust there, albeit pronounced by the flash of the camera. 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. [–]spasysheep 0 points1 point2 points 9 years ago (0 children). [–][deleted] 0 points1 point2 points 9 years ago (0 children). If you can create a strong flow over your CPU using an exhaust fan, do that. As a rule of thumb I usually use around 150% of the exhaust fan displacement on the intake. Building a modern desktop PC is surprisingly easy, thanks to modular parts and a lot of solid engineering. Do your back and ass a favor and ditch the gaming chair. [–]vcarl 1 point2 points3 points 9 years ago (2 children). Airflow is important in choosing the best PC case, especially when it comes to high-end components in tight spaces. Great read. As an added step, I would filter the fan if you make it intake. In the negative pressure setup pictured here, assume the top right fan is non-existent, and replaced by a vent or grill. 1 fan in the back is good, add 1 fan in the front and it's better. 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. If your fans all have the same CFM rating, then you will have a "positive pressure" system if you have more intake fans than exhaust fans. Because of this, you should configure your system based off how powerful your fans are and also the layout of your case. Would you say this diagram is ideal, if instead of 2 optional fans behind the HDDs they be installed on the side panel? CFM is cubic feet per minute and is how fans are rated, but is not always the most reliable stat, hence the imprecise science part. For less dust in your case, try to have positive pressure. having 8 small 110mm fans at 10% speed instead of 2 120-140mm fans operating at 100%. This video demonstrates "positive pressure" airflow, but please take it with a grain of salt, since the pressure gradient is most likely tiny (and ignore the YouTube comments). How to check if fans are intake or exhaust? If you aren't careful, it can condense on your computer and it's parts, and that is a bad thing. We’re talking about physics, thermodynamics, all sorts of fun stuff. 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? Just because you don’t have a super-high-end system doesn’t mean you should forego doing cable management. 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 … would that be enough? This is because the syrup is more dense! This post is so I remember to come back and read this. Otherwise, the cases airflow isn’t very good and the cooling of the components isn’t efficient. 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. The most important thing is that your system is constantly supplied with cool, fresh, dust free air. It depends on whether you care about noise and dust. This guide will help you find the best PC case for your needs. [–][deleted] -3 points-2 points-1 points 9 years ago (11 children). There are dust filters on each of the intake fans and one over the PSU intake grill so the case is always dust free. [–]drockers 0 points1 point2 points 9 years ago (0 children). All the above assumes that all fans are of identical performance, and that you are using a dual fan air cooler in the top. Like, if you dont have top slots for fans, I probably shouldnt max out intake in the front and bottom with only 1 exhaust right? Choosing a good cooler for your CPU and doing a good job with your thermal paste is 1000x more important. Good. The performance doesn’t just cater to airflow fanatics, however. Positive airflow Make sure you're using some canned air on your pc quite regularly if you're gonna do that. If you have a grill or mesh without a fan on it, you can leave it open or closed. In the case of a PC, the syrup is the cold air, while the water is the warm air! After I installed the second card, the average CPU temperature rose ~10 degrees, which isn't much but it tells me that there is a build-up of warm air in the case. I wouldn't say 1000x because I don't spit out numbers unless I can substantiate them. [–]mckirkus 0 points1 point2 points 9 years ago* (0 children). Also note that filters only need to be placed on intake fans. Top 10 Best Airflow Case Buyer’s Guide 2020. High airflow and static pressure fans blow air through your PC, but they do it in different ways. Posted by Reddit user u/sourcekappie here. Exhaust fans don't need covers. 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. I recently dusted my pc and it was pretty damn dusty. As for thermal paste, less is more, and they're all basically equivalent. I've seen a lot of talk around the internet regarding PC airflow. I just leave the side of my case off and occasionally point a box fan into it. Here's my PC. 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. You can make a cheap filter by using women's pantyhose/tights and wrapping them around your fans (stay tuned for this!). My computer is near a window and when it is cool outside (around 60 F), my temperatures are NOTICEABLY lower, especially the CPU, which may drop by ~8 C on idle (this comes with a 10 C drop in ambient temperature). Besides, anyone with modern graphics card pretty much need a side intake fan to cool them. REDDIT and the ALIEN Logo are registered trademarks of reddit inc. π Rendered by PID 842 on r2-app-0c86560e31d3c7463 at 2021-01-07 22:17:30.911830+00:00 running 22f414d country code: US. These high airflow PC cases come with mesh front panel, plenty of fan mount points and good ventilation. The direction of the fans push the cool air from the bottom in the same direction as hot air would normally rise and there are no obstructions to air flow, all the cables are tucked away neatly. For PC - Hardware Discussion on the PC, a GameFAQs message board topic titled "Guide to airflow? Closed will allow your case to sustain more pressure, open will allow more places for air to come in/seep out. This can be fixed by removing the left fan, moving the fans further apart, or flipping the direction of the left fan. If you tilt them at an angle, the water will fall out of the cup quite quickly while the syrup will crawl along. [–]dopamean 1 point2 points3 points 9 years ago (1 child), I have a Silverstone FT02, I think it has the best air flow out of any case I've ever used. Has anyone got a guide for getting the air flow right. It has 3 x 180mm intake fans and 1 x 120mm exhaust fan so in terms of positive pressure, it has plenty. Conversely, a negative pressure system does just the opposite as a positive pressure system. 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. To avoid any confusions, we are only going to look at the 5 best airflow pc cases available in the market. Cut a piece of paper towel about one inch wide and six inches long. And then move the PC over to the right? Air, as you should know, is a fluid, and its movement is therefore governed by the laws of fluid dynamics. I am getting a 400R tomorrow and have been looking for suggestions on airlfow. It is a great idea if your air is moisture free. You will also notice that there is a circulation cell near the graphics cards, which is hard to avoid with this setup. You could also run one of the top fans as an exhaust and one as an intake, but this could also adversely affect cooling due to the top intake fan drawing in air that was just echausted, as there is open space between top fans and the top fan filter. Realistically, the positive pressure and negative pressure systems will be very similar. Rendered by PID 842 on r2-app-0c86560e31d3c7463 at 2021-01-07 22:17:30.911830+00:00 running 22f414d country code: US. 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.. Maybe without the rear fan. Larger fans tend to have higher CFM ratings, and anything obstructing a fan will lower it's CFM. [–]Ender11 0 points1 point2 points 9 years ago (1 child). did it not say thats bad because it blow the heat from the gpu onto the cpu ? Cooler Master H500M – View on Amazon. It’s often explained as “LEGO for adults.” But managing the air cooling system within a PC is considerably more complex. This page has a few good diagrams that will help demonstrate the different setups. I guess I would have to factor my current fan configuration and possibly moving stuff around. 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. Maybe this is the right place to ask what the logistics would be behind wanting to run cold air from outside and use it to keep my computer cooler.
