Easy Ways to Cut Computer Noise

1. Move the PC
First, try a simple solution. If your system is sitting on the desk next to you, move it onto the floor (assuming that its case is designed to sit vertically rather than horizontally). The vibration from the PC often sets up a sympathetic vibration with the desk surface, turning the case into a soundboard. Moving the computer under your desk can eliminate this problem.
You'll get the best results if the PC sits on a carpeted surface. If you have a tile or hardwood floor, try putting the system on a carpet scrap or a piece of packing foam. For a really "far out" solution, purchase keyboard, mouse, and monitor extension cables (available from any computer dealer) and move the PC farther away. This will, of course, make the CD or DVD drives harder to access.
2. Tighten up to reduce rattling
Sometimes, the biggest contributor of PC noise isn't so much the direct sound of fans and motors as it is the vibration of PC components. It can be as annoying as a rattle somewhere in your car. You can often solve these problems by unplugging your PC, removing its cover, and methodically tightening the mounting screws of parts such as the power supply, drives, motherboard, and cooling fans. Be careful, though: Overtightening screws is worse than leaving them too loose, since you could damage components. Some noise-reduction kits include screws with polymer or rubber washers to reduce vibrations further.
3. Install gaskets

Inexpensive polymer gasket kits can isolate vibrating fans and parts from the case, reducing noise. NoiseMagic's No-Vibes hard-drive suspension kit can do the same for your hard drives.
4. Install heat-sensitive case fans
Because of the heat generated by fast processors and other components, almost all PC cases have one or more fans dedicated to exhausting heat. The inexpensive fans that many manufacturers use can be noisy, but fans don't always have to work at full speed, since a PC produces much less heat when it's idling.
Thermostatically CPU fan use temperature sensors that slow the fans down when the internal case temperature drops.
Alternatively, some manufacturers supply single-speed fans that are designed to be quiet. Installing them is usually simple, though you may need to remove drives or add-in boards to take out the old fan and insert the new one. Note whether the fan power is connected on the motherboard or to a power-supply connector. If your new fan has an external temperature sensor, follow the manufacturer's directions to place the sensor in the optimum location.
5. Upgrade to a quiet power supply
Your computer's power supply may be one of the primary sources of noise. Many rely on two built-in fans to move large amounts of air. Switching to a power supply that is designed to be quiet can dramatically reduce your PC's overall noise level. Designs vary, but most units simply employ larger fans that can turn more slowly while delivering the same amount of cooling air. Some also use thermostatic controls to slow down or speed up the fans depending on the case temperature. For instructions on upgrading your power supply, see "Keep It Powered, Keep It Cool". Be sure to buy a power supply that has sufficient wattage to handle all of your PC's components.
6. Install a new CPU fan
Today's processors run very hot--often from 145 to 175 degrees Fahrenheit. At these temperatures, effective and continuous cooling is essential. In fact, an uncooled CPU can grow hot enough to damage itself in a matter of seconds. The CPU heat sink and fan that came with your PC are probably louder than you realize. You can lower the noise by installing a specially designed CPU fan. Most coolers include a larger, more efficient heat sink that can be paired with a much quieter fan. Buy a cooler that's designed for your processor, and follow the manufacturer's directions for installing it.

How to Reduce Computer Fan Noise

Instructions  Preparation

1.Save your work before closing programs that you are using on the computer. Shut down your computer before you begin cleaning dust from inside the CPU fan.

2.Observe the location of each device that is connected to the computer. Unplug each device from the computer, including the monitor, power cord and every peripheral device connected to the computer.

3.Move each disconnected peripheral device away from the work area. During the cleaning process, there will be dust flying, and it could get inside the peripheral devices and compromise the quality of performance.

4.Use an appropriate screwdriver. Remove the screws holding the top or side of the case in place. Set the case away from the work area to avoid flying dust particles collecting on it.

5.Gather the cleaning supplies near the work area. Gathering the cleaning supplies near the work area can save a significant amount of time because you don't have to keep going to another room to gather supplies.

Remove Dust from the Fans

6.Use a cotton swab. Remove as much caked-on dust from the fan blades of the CPU fan and the power supply fan with a cotton swab as you can. Caked-on dust is hard to remove with a can of compressed air.

7.Attach the spray nozzle to the can of compressed air. Be sure to hold the can of compressed air straight up. Make gentle sweeps across the blades of the CPU fan and power-supply fan to remove loose dust and cobwebs. Blow the dust to one empty corner of the computer where there are no devices connected.

8.Check for dust in other inside areas of the computer case such as on top of memory sticks and network cards, graphics cards and ports. If there is a significant amount of dust in other areas of the computer case, repeat the dusting process to blow the dust to one corner of the inside of the computer.

9.Use a vacuum cleaner crevice tool. Gently vacuum the dust from the corner of the inside of the computer case with a gentle sweeping motion.

10.Replace the top of the case. Be sure to tighten the screws snugly. Tightening the screws loosely leaves the case open to further dust buildup in the future.

11.Reconnect the peripheral devices and the power cord. Boot the computer normally and verify every device is in working order.

How To Troubleshoot a Noisy Computer Fan

1.Clean the CPU fan.

2.Clean the power supply fan.

3.If the noise persists and can be narrowed down to the CPU fan, replace the CPU fan.

4.If the noise persists and can be narrowed down to the fan inside of the power supply, replace the power supply.

Note: Due to safety concerns, it is never recommended to open the power supply and replace only the fan. I always recommend that the entire power supply be replaced instead.

5.Many fans in perfect working order will simply get louder as the system gets hotter. In this case, it may be necessary to move your PC to a cooler area.

6.If moving the PC is not an option, you may need to invest in more powerful CPU fan or in a more advanced cooling system like liquid cooling.

How to remove a computer CPU fan

Removing a computer processor fan from the computer is a relatively simple process and may be necessary to clean the fan or to replace a bad or noisy fan. Below, are the steps required for removing most computer processor heat sink fans.
Caution: While inside the computer, make sure it's off and that you're familiar with ElectroStatic Discharge (ESD) and its potential dangers.

Removing any covering
Before removing the heatsink from the processor make sure the processor is visible. If any duct or ventilation system is above the CPU it must be removed fist. In the below picture, is an example of a processor duct system in an OEM Dell XPS computer. The CPU fan for this computer's processor and the duct will not be visible until this is removed from the computer.
In the case of this computer, the duct system can be removed by pressing in on the clips and pulling the duct away from the case and the processor. After the duct has been removed the computer processor and the heat sink should be visible.

Disconnect the fan
Before disconnecting the heat sink fan from the computer it must be disconnected from the motherboard or its power source. A two, three, or four pin power cable should be connecting the fan to the computer motherboard. Locate where this cable is connected and disconnect it by grabbing on the connector end and pulling up on the connector.
Caution: If the connector is accessible, do not pull the wire by the cable. Instead, disconnect the cable by pulling on the connector end. Pulling on the wires may loosen them from the connector.

Unclip the heat sink from the processor
After the wire fan has been disconnected from the computer locate the clip holding the fan to the processor. In the picture to the right, is an example of what this clip may look like. In this example, inserting a screw driver into the small hole and gently pressing down and away from the processor will unlatch the heat sink.
Tip: With some computers the fan may also be screwed into the heat sink. If you see screws on the heat sink and you only wish to remove the CPU fan, unscrew any screws and disconnect the fan instead of unlatching the heatsink. All of the below steps can be skipped if the fan was able to be removed this way.
After the clip holding the heat sink in place has been unlatched the heat sink can be pulled away from the processor.
Caution: Do not pull hard, the heat sink should be able to be removed with very little upward force. In some situations the Thermal compound or thermal pad that allows the heat to be transferred to the heat sink may have a strong hold preventing the heat sink from being removed from the processor. This can almost always be overcome by gently twisting the heat sink while pulling up.

How to Troubleshoot a CPU Fan

As you use your computer, the hard drive and other devices in the computers central processing unit (CPU) can heat up and cause your computer to run very slow or even stop completely. To prevent this, a fan has been installed in your CPU, and is vented out the back of the case for your desktop computer. This allows the interior hardware to remain cool and continue working normally. Regular inspection and troubleshooting of your CPU fan will keep your computer running and may even extend the life of your system.

1.Check the location of your CPU to verify that the back of the case is not up against a wall or being covered up by and loose materials. If needed, relocate your computer to an area where it can vent out the back of the CPU properly.

2.Turn the computer off and remove the case from the CPU by undoing the screws in the back of the unit with a screwdriver. Slide the case forward and remove it from the CPU base.

3.Locate the CPU fan on the inside of the unit near the back and check for any dust or debris around the fan. Use a can of compressed air to remove the dust from around the fan. Check the back of the unit where the air is vented out for any signs of dust build up as well and use the compressed air to clean it away.

4.Follow the electrical wires from your CPU fan to the power supply and remove any dust from around the electrical connectors in the power supply with the compressed air. Unplug the connectors and check for any signs of decay or anything that would prevent their normal operation. Once you have inspected the electrical connectors, reattach them to the power supply.

5.Turn the computer back on with the top of the case still removed and check to see if the fan is working normally. If the fan is still not functioning, you will have to replace it by unscrewing it from the back of the CPU and installing a new CPU fan.

6.Slide the CPU cover back over the top of the base when you have completed your troubleshooting of the CPU fan. Secure the cover by reattaching the screws in the back of the unit with a screwdriver.

How to Choose and Mount a CPU Fan: Everything You Need To Know

Are you looking to mount a new CPU fan? Finding the right CPU fan requires a great deal of research. Not only do different fan sizes populate the market, a byzantine maze of CPU socket types, bearing technologies, fan speeds and more greatly complicate the selection process. Fortunately, you’ve come to the right place.

This how-to guide explains the nitty-gritty of getting the right fan and mounting it to your PC’s CPU. Additionally, it explains my favorite method for applying thermal compound to a CPU.

If you’re simply looking for installation instructions on how to mount a CPU fan, skip to the second part of this article.

What Kind of CPU Fan Do You Need?

The PC component that keeps your CPU cool consists of two separate parts – the heat sink, which is typically a block of metal, designed to maximize airflow and surface area. The second part is the fan. Together they’re commonly referred to as the heat-sink/fan combo or HSF, for short. Lots of technologies and aftermarket products exist. Some are designed to reduce noise while others are designed for maximum cooling. All of them, however, require you know a few things about your computer.

Determining what sort of CPU fan you need takes five steps.

• First, find your motherboard’s CPU socket.
• Second, measure the available height in your case between the top of the CPU and the panel of the computer’s chassis.
• Third, inspect the area on your motherboard surrounding the CPU socket.
• Fourth, determine how fast you want the fan to run.
• Fifth, find the Thermal Design Power (TDP) of your CPU, if you are not using the stock (the one that comes with the CPU) HSF combo. TDP is the heat output of your CPU, measured in watts.

How to Install CPU Fan

The Central Processing Unit or CPU is the component of a computer that processes all information and also known as the computer processor. The processor tends to heat up when being used. The processor tends to melt or break down when the heat produced is not dissipated. The CPU fan cools the computer’s processor and prevents it from breaking down. For better cooling function, the CPU fan is installed with a heat sink. A heat sink is a metallic device that attaches directly to the CPU, drawing away the heat of the CPU through its aluminum fin-like structure. CPU fans, along with heat sinks, come in a wide variety of designs and sizes. Most new processors come with their own CPU fan and heat sink.

Step 1

Choose an appropriate CPU fan and heat sink. If the processor does not come with its own CPU fan and heat sink, a fan appropriate for the processor must be bought. The fan appropriate to the computer may be seen on the computer’s manual. The available space inside the computer’s casing must be taken into consideration when installing a CPU fan.

Step 2

Shut down the computer and open the casing so that the CPU is exposed. Set aside screws, clips, and the cover for the CPU.

Step 3

Affix the CPU fan to its heat sink. This may have already been done. If the fan has not been attached, carefully fasten the fan and heat sink together by using the screws that came with the device.

Step 4

Attach the heat sink and fan to the CPU. The method of attaching the heat sink and fan to your CPU differs for CPU, CPU fan, and heat sink. A thin layer of heat sink compound may be spread on the CPU’s surface to ensure contact. Some fans and heat sinks attach to the CPU chip with a number of clips. Attach the fan gently with an even amount of force. Make sure not to damage the CPU and the motherboard of the computer.

Step 5

Connect the power cable of the heat sink and fan combination to the 3-pin power lead found on the computer’s motherboard. Search for a label 'fan' or 'CPU fan.'

Step 6

Replace computer cover and test the CPU fan.

What is a CPU Fan?

A Central Processing Unit (CPU) is the main microchip in a computer, while a CPU fan is the dedicated fan that helps keep the processor cool. Processors generate heat from internal electrical energy. The more demand placed on a CPU, the harder it works, and the warmer it gets. If the CPU gets too warm it can make errors and eventually ‘melt’ becoming completely inoperable. A CPU fan works in conjunction with a heat sink to prevent this.

A heat sink is a metallic device that sits directly on the CPU, drawing heat away from the chip into its cooler, aluminum, fin-like structure. The CPU fan attaches to the heat sink, pulling air through the fins. By dissipating heat drawn into the heat sink, the CPU fan indirectly cools the processor.

A CPU fan can come in a variety of sizes and is normally sold with a copper and/or aluminum heat sink. Specifications include diameter and whether the CPU fan uses ball bearings, thought to be quieter than non-bearing fans. The CPU fan and heat sink will also indicate which processors it is compatible with, or rated to cool.

Processors that are sold with a heat sink and CPU fan normally carry a 5-year warranty, while those sold without commonly (but not always) carry a warranty of one year. While the processors might be identical, manufacturers know that inadequate cooling can drastically shorten the life of a CPU. In the case of a CPU sold without a heat sink and CPU fan, the manufacturer has no guarantee that a customer will provide proper cooling.

Overclockers are computer enthusiasts that “push” CPUs, making them work faster than their marketed specifications. This causes the chips to run hotter than normal. Many overclockers prefer to provide their own advanced, aftermarket heat sinks and fans to protect overclocked CPUs. These heat sinks are normally taller than average, and the CPU fans are often more powerful while being quieter, adding less noise to the system than many commercial fans.

If you would like to purchase a CPU fan and heat sink, measure the available space inside your computer case before shopping, particularly if you plan to buy online. Advanced heat sink designs are often very tall, and not all computer cases can accommodate all models. Customer reviews, available at many online retailers, can give you a good idea of which CPUfans and heat sinks are most popular.

Computer parts drop noise of the CPU fan

Core tip: many friends are reaction own computer too much noise noise. Actually the biggest culprit is CPU fan. Generally speaking, the new buy fan always noise is small, and the use of a period of time will be significantly bigger. In fact, the dust caused by fan noise is one of the important reasons cpu fan for rising, because all-pervasive dust can always

A lot of friends reaction own computer too much noise noise. Actually the biggest culprit is CPU fan. Generally speaking, the new buy fan always noise is small, and the use of a period of time will be significantly bigger. In fact, the dust caused by fan noise is one of the important reasons for rising, because all-pervasive dust can always drilling incomplete airtight case. When the CPU fan high speed rotates, the whirlpool effect makes the dust is easy to adhere to the fan on. There is no doubt that at this time will CPU fan tear open come down to clean a is very necessary, and in the dust out, we should pay attention to fan back and fin of crack, here is the most easily forgotten.

Fan back and fin of crack don't forget to clean up, here is very easy to accumulate dust

For oil bearing fan is concerned, motor  cpu fan drive shaft after a long time work less flexible is often the things. Therefore, suggest that we in this position add lubricating oil, recommend mechanical lubricating oil or gasoline engine oil. Of course, in the add lubricating oil must be careful, do not let it overflow.

In addition, the vibration problem is also need our attention, usually high speed rotating fan and cooling fin occurred high frequency collision, if the fan and cooling fin then stable appropriate, collisions vibration noise can be greatly reduced. Such as the high speed rotating CPU fan take in hand, the noise is far less than the fixed in the radiator, this is because the soft hands absorbed a large number of vibration. According to this principle, in the fan corners and fin between contact with 1 ~ 2 mm thick soft gasket (such as leather, rubber), can effectively reduce the fan and cooling fin vibration produced by the noise.

Special fan governor, some fans  cpu fan have the speed regulating function

In the summer, many users can choose to stop overclocking, the high power fan obviously is unnecessary. Lead to fan sound too much the most main reason is that it extremely high speed. If we will fan droop down, so the noise problem will be further ease. In fact, even if we use the CPU fan can't adjust speed, we can also through the special fan governor and make up. ZALMAN company launched FAN MATE1 FAN governor in the domestic market is very popular, kyushu Aeolus have similar products. The use of this kind of fan governor is very simple, you only need to will CPU fan power interface on fan governor, and then fan governor connection on the mainboard CPU fan power interface can be.

As for the beginning ability strong user, you can try to reduce the working voltage of the series resistance method. As for the resistance value, we can use the CPU fan on the nameplate calculation (remember P = UI, R = U/I can), and at this time we can get any voltage. Want to remind everybody  cpu fan finally, reduce the CPU fan speed after, must in the BIOS open the corresponding temperature monitoring function, to ensure safety. Of course, when that can put the alarm temperature and shutdown temperature setting a few higher.
