Why computer noisy

The first step to fixing excess noise is to pinpoint the issue. The two biggest culprits for excess noise in computers are fans and the hard disk. Fans are used to move the heat produced by the processor, motherboard, and graphics card out of the computer.

If the fans are loose, too small, or not powerful enough, they can create noise. Hard disks can also make noise as the platters spin and the head seeks data. Loud noise is generally a very bad sign and should be dealt with immediately. Computers can also make noise if any components have come loose and are vibrating against the frame of the computer. If the computer is in the wrong area, any noise from inside the computer can become amplified.

As computers age, they acquire dust, pet hair, and lint, which can block fans from running efficiently. Parts can also come loose, or just wear out, increasing vibrations and noise. If you have a particularly powerful computer, there will be more fans inside the case and some components, such as the graphics card will have their own fans.

More fans mean more noise, especially as those fans get older. There are three levels of steps you can take to quiet your computer, depending on what part is making the noise. Make sure there are rubber feet on the bottom of the computer and that they are resting on a flat surface.

If the rubber feet are missing, you can get replacements, or put the computer on a piece of carpet or another soft surface. If the room is warm or the computer is otherwise overheating, there are cooling pads that can help cool the computer and absorb some of the sound and vibrations.

If the fans are the source of the noise, then this will aggravate the problem. Take the back off your computer and check all the attachments; screws, gaskets, and grommets. CD-ROM and other disc drives may generate noises when the drive is accessed. If any of the issues above occur, the drive is likely defective, and we recommend it be replaced.

Many computers have several fans to help provide ventilation to the computer's components. Below is a listing of the fans that cause noises in your computer. Case fans are fans commonly attached to the front or back of a computer. It is normal for most additional case fans to generate additional noise usually a low hum.

However, any clicking noise or high pitched noise from any of the case fans should not be heard. When this occurs, it's a good indication that the fan is failing or has already failed. Although not installed on all computers, some computer heat sinks may also contain a fan to help with keeping the processor cool.

It's also not uncommon for a fan to go from quiet to loud while you're working on the laptop. Most computers and laptops adjust the fan speeds when the processor is working more, or the computer is getting too hot. You should only expect to hear a slight hum from the CPU fan. Below are some issues that may cause additional noise from your CPU fan. The computer hard drive is a common issue for additional noise. Before cleaning your computer, turn it off and unplug all cables and connections, especially the power cable.

Cooling fans and other hardware inside a PC case. If you can, open up your computer to directly clean your CPU fan. To remove any dust build-up, spray the fans in short bursts with your canned air, then wipe down the fans with a microfiber cloth to finish the job. If your desktop computer has a dust filter inside, clean this out as well.

Do not open your power supply , but clean it as best you can from the outside. Finally, inspect the thermal paste on your CPU and any other units that have some. Thermal paste helps your CPU and GPU transfer heat to their heat sinks, and this paste can wear down over time, becoming less effective. If you notice any aging or worn down thermal paste, replace it. Now that your computer fans are nice and clean, put everything back together and turn on your computer.

Cracking open the power supply can be dangerous. Also, an overheating power supply may be unable to sufficiently power all the components in your computer. So rather than replace the fan, upgrade to a more powerful power supply instead. Older and less-powerful computers may struggle to keep up with modern video games — such as GTA V , Dark Souls , and Ark: Survival Evolved — as well as other complex applications, like multimedia editing software.

But if you notice certain programs consistently sitting at the top and consuming double-digit CPU resources, make a note and conduct further research. Updating or reinstalling the troublesome program might help calm things down and reduce your fan noise. This especially applies to your graphics driver.

If your GPU fan is making a lot of noise, update your drivers and see if the fans quiet down. AVG Driver Updater makes updating your drivers incredibly easy by scanning your computer and automatically updating any outdated or malfunctioning drivers.

Switch to the Disk tab. This will show you which programs are taking up the most storage space. Disk usage problems can often be resolved by updating Windows, removing malware, disabling the Windows Superfetch service , or clearing out junk files with a performance optimizer like AVG TuneUp. Viruses and worms will hog both as they replicate and store copies of themselves in your computer.

A malware detection and removal tool from a reputable provider is your strongest ally in the fight against resource-hogging malware. Without malware gobbling up your CPU power and disk space, your fans will have a much easier job.
