Do not buy a case that causes any obvious obstructions to air flow. Rear and top fans should always be exhausts, expelling the rising warm air from the case. The radiator and fan combo itself can be mounted to the front or bottom for intake or the rear or top for exhaust, but it will be less efficient than a fan alone. How-To Geek is where you turn when you want experts to explain technology. The stock case doesn’t offer many options for placing the unused power supply cables out of the way, but you should still try to tuck them away somewhere as best you can. It does, however, stand out in terms of air and water cooling support. If you’re looking into a water cooled setup that uses liquid convention to draw heat directly from your CPU or GPU to a radiator, odds are that you’re already working on a pretty advanced build. Do not run your PC in any sort of enclosed box. Most cases include multiple mount points for case fans—sometimes even more mount points than included fans. It is united by the need for compactness, yet divided in the aim of different products. When heated, this liquid becomes a gas and travels up the heat pipe where the heat load is spread across the aluminum fins and dissipated by a fan. The easiest thing you can do to help keep your computer cool is to give it a little … In the past this simple air exchange was enough, but in modern systems with powerhouse (and often multiple) video cards, large banks of RAM, and overclocked CPUs, more thought needs to be put into how air travels through an enclosure. Dust accumulation is a major hazard to electronics, as it is an insulator and can clog up exhaust ports. Avoid running your PC directly on a carpeted surface in order to reduce the accumulation of dust and fibers. The liquid moves heat to the radiators, and efficiently blows it out of your case. The circuit boards were completely immersed in a non-conductive fluid called Fluorinert™ which was cleverly re-circulated throughout the entire system. Clean your PC on a regular basis! Air cooling is a simple but effective way to cool your processor. Fans force air to move, so the hot air is blown away from heat-generating components and expelled from the desktop or laptop PC‘s case. Having the ability to remove superfluous cables makes for a much cleaner system, and allows you to easily add cables for hardware acquired in the future. Thermaltake Core V31 is a modular case that can be used to build a water-cooled or air-cooled PC for gaming. Noctua has refreshed its visuals … He’s covered industry events like the Consumer Electronics Show (CES) and Mobile World Congress in person. He spent five years writing for Android Police and his work has appeared on Digital Trends and Lifehacker. Noctua NF-S12B redux-1200. Remember, case fans draw in air on the open side and expel air on the grille side. The first step in any PC build is to buy a good quality case that already comes with the fans that you need, and none that you don’t. By submitting your email, you agree to the Terms of Use and Privacy Policy. Allow for Air Flow. This fan is expelling heat directly from the CPU into the case’s main airflow lane. For example, side-mounted hard disk caddies are fantastic, but if they also require you to install the disks vertically, they are obviously going to seriously impede air flow. Ideally, you want to place an exhaust fan as close to the CPU as possible to quickly expel this hot air. In simple terms, a computer case can either have: Positive pressure – The case fans push more air into the case than then pull out, so there is more air pressure inside of the case. Both approaches have their advantages. Others mount the PSU at the bottom of the case, rather than at the top to avoid hot air from the working components passing through it before being expelled. It also includes two 5.25-inch bays, which can be used for an external optical drive and you can also fit a 5.25-inch Fan Controller to other. Your CPU has its own heatsink and fan, even if you haven’t added one yourself—it’s the only fan directly mounted onto a motherboard component. Air-Cooled. Cables, especially the large bundled rails from a power supply, can be especially troublesome. Ive had to buy some quieter fans in the past, but otherwise Ive always been fine with air cooling. A liquid cooling system uses water or another liquid to cool the CPU. Big air coolers tend to take up more internal space in your PC case, particularly when it comes to vertical clearance off your best motherboard. Air cooling Air cooling is the cheapest and most common cooling type. The case is simple in looks and is very spacious from inside. Where possible, choose big. Here’s a really nice example of a case with good cable management creating open airflow. All Rights Reserved. These variables shouldn’t have any significant negative effects on air flow, but could change your cable management plans. The top and rear fans are exhausts, expelling the warm air out of the case and away from the internal components. Other methods exist, but are generally reserved for enthusiasts. To keep your machine cooled down and happy, you need to invest in an appropriate CPU cooler. We strongly encourage you to read our updated PRIVACY POLICY and COOKIE POLICY. All of these fans work cohesively to keep the vital components in the system at an optimal temperature level. But there are a few basic principles you can apply to almost any build to get optimal airflow, and thus, optimal cooling. © 1996-2021 Ziff Davis, LLC. Air cooled computer’s all components are cooled with air, to make your air cooling efficient, follow the instructions below to achieve the best possible result. CPU air coolers, despite what you might assume, actually contain a liquid. Since the inside of the case is usually quite warm indeed, this isn’t really a problem, but if you use the PC in a particularly hot room (like an un-air-conditioned garage in the summer) you’ll see less effective cooling. This newsletter may contain advertising, deals, or affiliate links. See it on Walmart. This is marketed to the extreme overclock/high voltage/high temp types; these people don't use air. But the drawback is that the slight vacuum it creates inside the case tends to draw in air from all the unsealed areas: the vents, unused PCIe slots on the rear panel, even the seams of metal in the case itself. The above article may contain affiliate links, which help support How-To Geek. Most large cases include a system of holes and guides that allow users to thread these cables away from the main open area of the case, often behind the motherboard tray. Air coolers are very price friendly, and the best ones are usually <$100. While gaming, this heat causes air cooler fans to run at a very high speed, producing noise. But there are a lot of great fans out there, so dig around sites like Newegg to see what you can find. Any loop consists of … And it has a trick up its sleeve that makes enthusiasts really happy. The fans on the front of your PC’s case are typically intake fans, drawing in the relatively cool air of the surrounding room to lower the temperature inside the case. The CPU cooler is the fan and heatsink connected to the CPU. (It isn’t totally enclosed, and the airflow generally isn’t equal, but we’re talking in generalities here.)

More dust means less efficient cooling…not to mention looking totally gross. This article will answer your liquid cooling vs air cooling dilemma by looking at how each works. Every six months or so, or more often if you live in a particularly dusty area, open up your computer and blow it out with some compressed air to get rid of any lingering dust. The central concept of air cooling is very simple. Deciding on a cooling approach that matches your case and your components before you go shopping for fans and coolers can be helpful. Cooler Master MasterLiquid ML240L RGB V2, Close-Loop AIO CPU Liquid Cooler, 240 Radiator, Du… The humble PC fan has been in active service for decades and remains the primary cooling method used in PCs to this day. Air coolers are great for lower-to-moderate overclocking (and even higher in some cases). This might seem obvious, but an air cooling setup relies on cooler air outside the case than inside. Liquid cooling a PC is a lot like a liquid cooled motor in a car or motorcycle. If you can, move your desk and your PC to a cooler room. The key to understanding air cooling is very simple – fans. It utilizes air to transfer heat away from the processor unlike AIO’s and custom loops. Fans mounted on the side of the case can be useful, but they often cause problems. Similarly, be sure to make use of all of the spacers that came with your case for unused PCIe slots, 5.25″ drive bays, and so on. Do not mount exhaust fans on the bottom of the case; since hot air rises, a bottom-firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. Fans on the rear and of the case are usually exhaust fans, expelling the hot air warmed up by the components back into the room. The Intake-exhaust direction should go front-to-back and bottom-to-top. If you’re seeing too much dust buildup, move one of your output fans to an input position. Most cases sold for system builders come with some kind of dust filter, but if you need more, you can buy some nice magnetic ones in different sizes for your intake fans. Fans on the rear and of the case are usually exhaust fans, expelling the hot air warmed up by the components back into the room. If you are a smoker, it is highly recommended that you do so away from your PC. How to Manage Your PC’s Fans for Optimal Airflow and Cooling, adjust your fans’ speed for the perfect balance, coupled with a “tricked out” overall build, How to Quickly Open Apps in Split View from Search on iPad, How to Set Up Customizable Motion Zones on Ring Security Cameras, How to Save and Download Apple Fitness+ Workouts, How to Put Your Xbox Controller Into Pairing Mode, How to Turn Off Read Receipts in Signal (or Turn Them On), © 2021 LifeSavvy Media. From the radiator, it flows into a block on a component that produces a lot of heat. This is best achieved by using a larger, low RPM fan. It is very difficult to remove from components, and causes them to fail much faster than they would otherwise. Cases that use three fans aligned vertically on the front are a great place to start, as they draw in air evenly across the entire face of the enclosure. …And a not-so-nice example. Most people opt for a more balanced approach, leaning slightly toward negative air pressure (for theoretical cooling) or positive air pressure (for less dust buildup), and we’d probably recommend something in the middle there. If you’re desperate or frugal, you can even make them yourself with some panty hose. PCMag Digital GroupExtremeTech is among the federally registered trademarks of Ziff Davis, LLC and may not be used by third parties without explicit permission. Corsair … Exhaust fans go on the rear or the top. Building a modern desktop PC is surprisingly easy, thanks to modular parts and a lot of solid engineering. That means you should mount your intake fans on the front of the case, or occasionally (if you have a multi-fan setup or the front mounting brackets are blocked) on the bottom. This site may earn affiliate commissions from the links on this page. On Amazon. Air cooling is ideal if you are hoping to build a PC quickly at a lower cost. Small form factor (SFF) PC cases is a unique market. Please, throw away your floppy drive. That many intake fans will most likely contribute to positive air pressure within the case, though (See the advanced section at the end of this guide for details on case air pressure). Think of a PC case as an enclosed box, and the air going in or out of each fan as roughly equal. Even the most carefully-constructed build will accumulate dust from the surrounding room, and if you live in an especially dry, dusty environment, (or you smoke, or have pets, etc.) Cleaning will be a important measure to take, at least until we are are all running coolers that de-dust themselves. Larger, lower RPM fans are generally far quieter and more efficient than their smaller, faster counterparts. The first is an air cooler, which comes with a big metal heat sink that pulls heat away from the CPU, which is then blown away by a … There is little point in putting thought into the thermal design of your PC build, only to then place it somewhere that won’t allow the warm air to dissipate. Im getting ready to build a new computer with an i9-7900X 10 core CPU, not overclocking at all, Ive always used air cooling as Ive been concerned with issues such as possible leaks and things. Consider spending extra on a modular PSU. As the components in your computer operate, they build up heat, which can lower performance and eventually damage the hardware if it goes unchecked. you’ll need to be extra vigilant. Do not install unnecessary hardware: Remove those old PCI cards that never get used anymore, leave the RAM module extra fan kit in it’s packaging, and consolidate small hard disks onto a single larger replacement. A water cooling kit will reduce the need to use more than one fan in your PC case. Because the liquid creates a much more efficient heat transfer, liquid cooling systems tend to be more effective and quieter. Since we launched in 2006, our articles have been read more than 1 billion times. Fans are generally mounted in the following locations: front, rear, top, and side.
