If reliability issues start cropping up (due to, e.g., overclocking a processor very high and constantly running heavy loads), running the part at a lower performance level may eke out a bit more life before the system is no longer reliable. PC cooling is a major factor to consider when building a PC. Make sure there's nothing sitting right against any side of the computer, especially the back. Be sure to unplug everything, don't carry too much at once, and sit things down very carefully. How a CPU Cooler Works Both air and liquid CPU coolers operate on a similar principle, and both do essentially the same thing: absorb heat from the CPU and redistribute it away from the hardware. Moving your computer can cause damage to the sensitive parts inside if you're not careful. Compressed air cans can be purchased at most electronics stores, but a better investment if you clean often is to get an electric duster. This dunks most of the hardware into a liquid, usually mineral oil for its inability to conduct electricity. Before thinking about overhauling your cooling setup or assembling components for a new build, here are some considerations to keep in mind. To the rest of you: you're well aware that overclocking pushes your computer's capabilities to its limits. These are not user serviceable beyond installation and basic maintenance. Connecting a 4-pin fan to a 3-pin socket. Just shut your computer off, open up the case, and use canned air to remove the dirt from each fan. This is common knowledge for many PC builders, but exploring why cooling is an integral part of a build can be useful, as is applying these principles to new builds. Water transfers heat well and can drastically reduce the temperature of a CPU. You can set your PC up to be ridiculously fast or whisper-quiet, and in both cases, cooling is key. Keep in mind that open-loop systems require a lot of investment and it makes the components being cooled harder to change out, depending on the availability of heat blocks. Tim Fisher has 30+ years' professional technology support experience. If your computer is really dirty, take it outside to clean or all that dirt will just settle elsewhere in the room, eventually ending up back inside your PC! There's a fan on top the CPU, one inside the power supply, and usually one or more on the front and/or back of the case. The two most common types of PC cooling are air and water cooling. If moving your computer just isn't an option, keep reading for more tips. PC Gamer is part of Future US Inc, an international media group and leading digital publisher. Water has a high thermal conductivity, meaning it absorbs heat very easily—even moreso than air. If your graphics card is overheating during gameplay, upgrade to a larger graphics card fan. Pick the Best Fans for Your PC Any desktop PC with standard case fan mounts will work (80mm, 120mm, 140mm, 200mm—it doesn’t mater as long as they’re consistent). The drawback to that is condensation can build up and create an electrical short hazard. One of the most effective ways to cool your PC is to clean the internal fans. Most take up at least one fan slot with a thick radiator, and the most extreme systems take up two fan slots with a double-width radiator built for maximum performance. The humble PC fan has been in active service for decades and remains the primary cooling method used in PCs to this day. Phase change units are the most drastic of cooling technologies. Visit our corporate site. At some point, the material cracks and breaks. It all finds a way into your computer and much of it gets stuck in the several fans. If you want to avoid the dust bunnies or fan noise, avoid cases with lots of openings. Most of the hot air flows out of the back end of the computer case. Heat may cause performance degradation, but by way of the component throttling itself to prevent it from getting hotter. The idea is that hot air is exhausted quickly while cooler air gets sucked in throughout the holes of the case because the air pressure is lower inside. An air-cooling solution that consists of a heatsink, heat pipes, and a fan. By When the case is left open, dust and debris clog the cooling fans faster than when the case is closed. While the resistance of a semiconductor increases, at around 160° C, its resistance decreases. Sure, you've heard about keeping your computer cool, but have you ever wondered why it's such a great idea? If you want to cool your PC's parts even more than a liquid-cooling system will allow, you can use Peltier devices in place of standard water blocks. For example, you can start with a CPU cooling loop, but if you want to add the video card, you can do so down the road. Water cooling When you apply electricity to it, heat moves from one side to the other. Over time, high heat accelerates wear and decreases reliability of the components. Otherwise, heat doesn’t affect anything else to a noticeable degree. Computers get hot, and they must be cooled. The liquid may still be pumped out to a radiator for cooling. Do not use a hand duster, especially something like a Swiffer, as these can build up static charges that can damage the hardware. You should periodically dust your workspace and clean your laptop with cotton swabs or compressed air - while it’s turned off - to prevent build up and excessive heat. If the door is closed all day, hot air tends to recycle inside the desk, getting hotter and hotter the longer the computer is running. You will receive a verification email shortly. TDP is not the same as power consumption. Case fans are even easier to install than CPU fans, so don't be afraid to get inside your computer to tackle this project. Smaller cases can be worked with, but components that need airflow (usually the processor and video card) should have vents closeby. This big boy houses twin cooling towers, seven heat pipes, and a pair of quiet 140mm fans. Sure, you could take the “maximum power” approach of shoving as many fans as possible into and onto the case, but that’s far from ideal. What Is Overclocking and How Does It Impact Your PC? Ensuring your computer receives sufficient cooling with PC case fans isn’t rocket science but it can be tricky. (Maximum PC) 14 September 2015. That doesn't sound safe!" Is There a Cheaper Alternative to Air Conditioning? When you apply electricity to a Peltier cooling module, one side becomes hot while the other side becomes cold. Some parts, like the CPU and graphics card, can get so hot you could cook on them. The idea is that this creates a clean-room environment in the case. Similar enterprise-level PC cooling products can be $10,000 USD or more! Liquid cooling kits are easy to install, even if you've never upgraded a computer before. This also prevents any hot exhaust air from being drawn back in. A clogged up fan does a terrible job at cooling your expensive computer components. Cool air enters from the front and sometimes from the sides of the case. Air cooling uses the case’s air as the primary cooling medium. Home Made PC Water Cooling: One of the most enjoyable things to do in your spare time is to make gadgets and mods to your computer. A Peltier device is a thermoelectric device. Liquid Cooling a PC. Similarly for the CPU cooling, the heat sink with a fan fixed to it is attached to the flat area of the CPU in order to cover maximum surface area. As far as noise is concerned, anything below 40dB will be very quiet, but start creeping up to 50dB and it’ll be loud. There are two properties of fans to consider: airflow (measured in CFM) and noise (measured in dB). Thank you for signing up to PC Gamer. In a gaming computer, this is usually air or when liquid-cooled water. Just to clear up some misconceptions though, here are two things about TDP you can take away: Lower TDP usually means both lower power consumption and lower heat generated. Your computer can heat up quickly if this fan isn't working. The parts inside most computers are cooled by air moving through the case. For the past three years, I've been water cooling my computer for ultra cool, ultra quiet performance. Each differ by what kind of physics magic they employ to do so. The power supply in your computer has a large fan built into it. How positive and negative case pressure works (from SilverStone). Liquid cooling should be considered if you plan on overclocking heavily or if the computer is constantly doing heavy lifting in hot environments. Most case fans also have three pins to connect to the motherboard or controller. An appropriate type of oil will typically be used for this. Dirt—in the form of dust, pet hair, etc. There is also active cooling where an additional device such as a fan is used, that with the help of a coolant transfers heat from one place to another. If your computer isn't removing the hot air fast enough, the temperature can get so hot that you risk serious damage to your PC. "Water inside a computer? The easiest thing you can do to help keep your computer cool is to give it a little breathing room by removing any obstacles to airflow. Just shut your computer off, open up the case, and use canned air to remove the dirt from each fan. Many companies sell large CPU fans that help keep CPU temperature lower than a factory installed fan ever could. Liquid-based CPU coolers often appear to be large and bulky systems at first glance. It does seem logical—if the case is open, there would be more airflow which would help keep the computer cooler. We’ll cover what generates heat and what effects heat has, ways to cool off components that need it, and tidbits of information to consider when setting up your cooling system. A phase change unit can be thought of as a refrigerator for your CPU. While all electronics give off some amount of heat, for many of them it is a negligible amount and doesn’t require any special attention. An example of a phase change cooler, from LDCooling. NY 10036. Your average store-bought PC uses a system of fans to pull heat off major … It’s also very expensive; you won’t have any use for one unless you’re in overclocking competitions. In very high-end computers, heat buildup can become such a problem that even the fastest and most efficient fans can't cool the PC. Another point is that hot exhaust air may be drawn back into the case. The hot side is cooled off by one of the other methods. As such, it's a great candidate for cooling your system.
