pc airflow guide reddit

Since you keep getting dust, you'll want positive pressure. [–]funktion 2 points3 points4 points 9 years ago (3 children). This is the place to ask! How to check if fans are intake or exhaust? Imagine that there is an intake fan in the 5.25" drive bays in the above picture, and both top fans were exhaust. The parts holding the motor centered should be on the exhausting side. 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 . I am getting a 400R tomorrow and have been looking for suggestions on airlfow.

It will most likely be this way for all systems. This provides positive pressure to reduce the dust taken in through cracks and non-fan vents in the chassis. 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 … The Silverstone link suggested that. Most fans blow exhaust away from the open sides. Looks like you're using new Reddit on an old browser. I recently dusted my pc and it was pretty damn dusty. 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). [–]funktion 1 point2 points3 points 9 years ago (1 child). And then move the PC over to the right? Realistically, the positive pressure and negative pressure systems will be very similar. Exhaust fans don't need covers. Exhaust fans should be on top and in the back. did it not say thats bad because it blow the heat from the gpu onto the cpu ? I agree, except I would add that a good side panel fan will help also. 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? I definitely recommend using top fans as intake. [–]ccampo[S] 1 point2 points3 points 9 years ago (0 children). Because of this, you should configure your system based off how powerful your fans are and also the layout of your case. Yeah, you've definitely got the theoretical aspect of it down, while they have experimental data. 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. 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. Anyone is welcome to seek the input of our helpful community as they piece together their desktop. When are we going to be able to build PCs Again? Posted by Reddit user u/sourcekappie here. 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. 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’s often explained as “LEGO for adults.” But managing the air cooling system within a PC is considerably more complex. Therefore, top fans do not always have to be exhaust, and can even be detrimental to airflow in some cases. It is a great idea if your air is moisture free. [–]vcarl 1 point2 points3 points 9 years ago (2 children). 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). 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. Understanding case airflow and the physics behind it (xpost from r/gamingpc) (self.buildapc). 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 … Press question mark to learn the rest of the keyboard shortcuts. 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. Should I? For PC - Hardware Discussion on the PC, a GameFAQs message board topic titled "Guide to airflow? You want to get rid of the hot air and not let it stay inside longer than it has to. Planning on building a computer but need some advice? Have you got any advice about when to cover grills? I would, yes. Would you say this diagram is ideal, if instead of 2 optional fans behind the HDDs they be installed on the side panel? In this case, the top right fan would actually suck out the cool air brought in from the fan in the 5.25" bays, depriving the CPU cooler of fresh, cool air. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. 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. edit: Corsair confirm for performance do the opposite of above. Consequently, since air will want to move towards the lower pressure system, outside air will seep through any nooks and crannies. [–]ccampo[S] 10 points11 points12 points 9 years ago* (5 children). Since there is more air inside the case than outside, the density of particles is greater inside, and therefore the pressure is greater inside. 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. ... High Airflow RGB LED Case Fan for PC Cases, CPU Coolers,Radiators System,6-Pack,SR12-06-6 is the suitable for you. Dust filter wise? I know this is a exception to the rule I have a silent case, the Fractal Define R3. I agree that that is a fantastic case for airflow, as everything OS perfectly laminar and obstruction free. The house does seem to be rather dusty, no matter how often we sweep/vacuum/mop. 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. It is definitely reversible, just flip it (not rotate). No submissions about memes, jokes, meta, or hypothetical / dream builds. 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. 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. What would be a good ratio? If you aren't careful, it can condense on your computer and it's parts, and that is a bad thing. [–]Grumpy007 0 points1 point2 points 9 years ago (2 children). [–][deleted] -3 points-2 points-1 points 9 years ago (0 children). 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. A Fitting Choice: Combining innovative cable management, concentrated airflow, and proven Corsair build quality, choose the 4000D for an immaculate high-performance PC. That in conjunction with the thermal armour on my Sabertooth motherboard and the dust filters on the case means I get almost no dust build up at all. 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. Conversely, a negative pressure system does just the opposite as a positive pressure system. 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. 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. [–][deleted] 2 points3 points4 points 9 years ago (1 child). You want to keep in mind whether any components are going to be stifled for air by any obstructions. The positive aspect of this setup is that the system will more quickly cycle out hot air. I drew out a positive pressure flow diagram to further demonstrate what is going on. In the negative pressure setup pictured here, assume the top right fan is non-existent, and replaced by a vent or grill. I would actually close them if I had any open meshes, mainly to reduce noise. 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). 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. As you may be able to tell there is some dust there, albeit pronounced by the flash of the camera. 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. I literally just thinking out loud on text. Do you recommend changing my top fan to an intake to create positive pressure? You can see that this creates a convection cell which possibly recirculates warm air into 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 PC is designed to deliver high performance on all of today's most popular games without being complicated to build or costing too much. Only on intake. pretty much, just the top-rear fan should be an exhaust instead. Just because you don’t have a super-high-end system doesn’t mean you should forego doing cable management.
