Proven methods to combat overheating computer
I love summer , I love when it’s warm and sunny. But our computers at this time begins to warm up and it is not good for them . And if now the computer does not overheat , it does not mean that the peak heat will not happen. So it is better to be prepared.
In this article we will talk about what terrible overheating why computers can be very warm and how to fight it .
1. sensor readings
Critical temperature sensor readings indicate overheating . For each piece of iron is its critical temperature. Offhand , temperature up to 70 degrees under load – it is almost always normal, with the exception of hard drives. Their heat better not to allow up to 50 degrees. Overheating of the hard drive is especially dangerous because you can lose all your data! With the overall heating of the computer , when working with hard drive (such as copying a large amount of information or continuous operation with a torrent tracker ) hard disk can be heated above the norm . Check the sensors by using the software supplied with the motherboard or using third-party software such as AIDA64.
If your computer has suddenly become slower to work , it does not necessarily mean that it is necessary to reinstall the system or to search for viruses , especially if slow performance coincided with the warming . When the CPU or motherboard chipset overheat , it is possible to reduce speed. Processor clock speed is underestimated , it starts less heated and you can continue working . But also possibly freezing the computer .
3 . A siren sounds
In the BIOS settings can be set from which temperatures will be published by the nasty tone. However, you will not hear if your motherboard is not connected ” Speaker .” But usually it is attached or built into the motherboard. If the siren screaming , then quickly turn off the computer better and start to understand what it is.
4 . The computer shuts down or restarts itself
Again because of the settings in the computer BIOS may itself off when it reaches a critical temperature. A siren may first begin to sound , and then turn off automatically. It is overheating the computer may reboot itself and hang.
5 . Fans have become stronger spin and make noise
Some fan speed can be controlled depending on the temperature. This works if the appropriate option in the BIOS and set up special software . Thus, above a certain temperature threshold fans will spin faster and more quiet.
6. ” Artifacts ” on the screen , or hang
If the video card is overheating , there may be “artifacts” on the screen or hovering. Basically, if the computer does not play, and work , the card should not overheat. I have already said that the video card are actively cooled (with fan) and passive (fanless ) . Unfortunately, the unfortunate circumstances passive cards can be very warm even just in Windows.
If no signs of overheating , it is useful at least once to run one of the diagnostic tools to check the “general temperature in the hospital .”
1. A weak or faulty cooling system
For each processor need a suitable cooling system , ie you can not take any suitable for attachment to the radiator fan and ” prisobachit ” it to the processor. For the budget processors fit small heat sinks , and for high-end , respectively , we need more radiators .
Cooling System Processor
The whole problem can be covered in a stopped or almost-dead fan. If they barely twisting , maybe it’s time to replace them with new ones. As shown, lubricate the fan does not make sense because it helps for a while. It’s better to just buy a new one, but if there is no store nearby , you can lubricate the existing fan. Well suited for this gear oil , which is used for transmission in cars. Conventional motor oil also can be lubricated , but it quickly spreads from the speed of the fan in the computer.
2 . Inadequate ventilation will
If the cooling system is working properly and appropriate and that the computer is overheating anyway , you should pay attention to ventilation of the enclosure . On the way the air flow must be unobstructed from thick cables. Modern computers stranded cables are not usually used , but you still need to carefully lay the wire.
On good in the body should be two fans , one blowing out the back wall , and one for intake on the front. This ensures a good flow of air from the front to the rear of the housing . The heated air is stagnant and not necessarily all happy to put two fans , because maybe one is enough. Especially more fans, the more noise computer. I adherent minimum noise from the system unit . Therefore the first set to a single exhaust fan on the rear panel and look what happened. In some system units can be installed two fans blowing out , or put the fan on the side cover. Experiment as in your case would be better.
Here ‘s a little trick : a larger fan at lower speed and noise level can provide the same performance as a smaller fan at high speed. That is, 120 millimeter cooler at 1000 rps , for example, can provide the same performance as 80 mm at 1500 rpm / s , while emitting less noise.
And sometimes quite bluntly – the fan does not spin because the blades hit the wire ! Perhaps someone is very hurry , gathering system unit
In order to cool the hard disk, you can use special fans directly to the hard drive. Or just install a hard drive directly above the fan on the front panel , if any.
The fan in the power supply also plays an important role in heat transfer of the entire computer . If you notice , the common power supply units are of two types: a 80 mm fan on the rear panel and a 120 mm fan inside of the processor. Power supplies with 120 mm fan takes hot air out of the computer and throw it out. That is, they are better for good heat transfer. There are also models with both fans , and generally without them.
Some people resolve all issues with overheating the computer using the open side cover just remove it and sit so the summer or even all the time. A good way of course , if the noise does not bother . But there is the danger . Passive radiators (no fans ) in this case are heated much stronger, up to a critical overheating. This may be a passive graphics card or motherboard chipset radiator . This is because the exhaust fan is idle , ie, does not take away the hot air . It sounds strange, but tested more than once on their own experience . For example , I have a video card with the lid open, basking in the body up to 85 degrees! Only had to lean against the cap , as the temperature dropped to 75 degrees.
3 . heavy dust
It’s no secret that at least once a year to take a look inside the system unit for dust. Clogged with dust radiators poorly cooled. If that is the case , then just clean this up properly inside the system , but only CAUTION Try not to touch anything .
4 . Improper attachment radiator
• Improperly tightened radiator forget to normal work . Whether it is a heatsink on the CPU, the graphics card or chipset on the motherboard. If the radiator is not firmly pressed to cover the processor core or chip , then what kind of cooling, can we talk?
To identify improper mounting the radiator try its temperature to the touch. If the temperature sensors are going through the roof , and the radiator just warm , then it is clear – it is not tight . You need to reinstall the radiator and / or clean up the processor cover zero sandpaper to shine and change the thermal paste .
5 . Marriage or frayed processor
Rarely , but it happens that the heatsink fits perfectly, but the problem remains. This can happen because of the processor with brachkom or if the processor is ” worn out “. The fact that the processor with a metal top cover has a special gasket , which acts as a thermal grease . This removes heat from the processor chip to the cover and the cover transfers the heat to the radiator. If the lid is not tight to the processor , it will overheat and the radiator will remain lukewarm. It is treated by removing the cover or replacing the gasket.
6. excess voltage
With excess voltage from the power supply hard drive can be very warm. In this case, the right to replace the power supply to the normal , or apply a special stabilizer that is inserted into the supply gap HDD. But there is no such stabilizers in the open market , and are used more for data protection. I was told about them just for information
You can check the voltage in special programs , but they often tell lies . Better to take the tester and measure up himself.
Because of the high voltage power supply of low-quality can bask not only the hard drive, but whatever. So the power supply must be of high quality , period.
7. BIOS and operating system
This is the easiest way to solve the problem of overheating the computer , and the most fun is that it does not require physical effort and investment Luckily , has long been a technology that allows you to reduce the frequency of the processor while it is idle . For AMD processor technology is called Cool’n’Quite, and for Intel – Enhanced SpeedStep Technology. This is a very powerful thing that helps to reduce the temperature. Now go and check quickly turned on the use of these technologies.
In Windows 7, go to “Control Panel – > Power Options ” and see what power plan is active . Usually, you can choose ” Balanced “, ” High Performance ” and ” Saving energy “. To work Cool’n’Quite technology Enhanced SpeedStep Technology , or select any other than ” high performance “. Do not be afraid , the performance will not suffer .
Energy saving technologies should be included in the BIOS. Usually it is, but if not, then go into the BIOS and load the default settings.
To check whether the power-saving technology , we need not require the installation free utility CPU Rightmark. How to use it to view the short video below article .
I must mention that when troubled or overclocked hardware failures can occur when the activation energy-saving technologies .
In good motherboards incorporated additional cooling technology chipset. For their work to study the instructions and software for a particular model. Who’s supposed to – understand.
