How To Quiet Computer Fans 2021

If you can hardly hear yourself think over the din of your machine’s Quiet Computer Fans, it’s time to figure out why your computer sounds like a wind tunnel. It may be a big problem, a mild annoyance, or something in the middle.

Check What software is running

Look at what program is currently running, and whether the fan noise is necessary before grabbing your screwdriver. To open the Task Manager on a Windows computer, press Ctrl+Shift+Esc and then click the More Details button. If you’re using a Mac, press Ctrl+Space and type Activity Monitor into the search box. To see if your CPU is getting heavy, you can download a program like Core Temp (Windows) or Temp Monitor (Mac).

If you’re not doing anything intensive right now, your CPU use in Task Manager should be low—less than 20%. Look at the list to see what software is consuming those cycles if your machine is idle and your CPU is consuming 100% of its power.

If the fan noise comes on when you’re doing something intensive, such as gaming or converting a big video file, that’s normal behavior.  It’s time to check the hardware.

Give your PC Room to Breathe

Okay, your machine doesn’t “breathe” like a human—the future of Blade Runner hasn’t arrived yet. If there isn’t enough space for air to flow around your PC, it can become hotter than it needs to be, forcing your fans to spin at full speed to cool it down. If you use a laptop, don’t place it on top of a pillow or other plush surface because the vents that enable air to flow in and out of the device will be blocked. (Lap desks are a much better option.) Anything that blocks airflow can cause your PC to overheat. This will force your fans to spin faster to maintain the desired temperature.

Set Up Fan control

Some PCs have their fans running , which is particularly popular if you designed your PC and didn’t fine-tune the cooling hardware. If your fans are connected to the motherboard of your machine, you might be able to check them via the BIOS menu.

We can’t walk you through the exact steps because every BIOS is different. Some may only have simple “high” and “low” fan settings, while others might have sophisticated fan curves that let you adjust the fan speed at different CPU temperatures. Some motherboards can control all attached fans, while others may only be able to control fans with 4-pin PWM adapters (rather than cheaper 3-pin fan models). Experiment with the fan control settings to see what works best for you.

If your BIOS doesn’t have any fan control options, you can use software like SpeedFan, but only if your motherboard is capable of controlling those fans. When it comes to graphics cards, MSI Afterburner will assist you in adjusting the fan’s actions during a heavy gaming session.

Certain hardware adapters can help if you can’t watch the fans with software. Low-noise adapters from Noctua work like a resistor, lowering the voltage sent to the fan and, as a result, lowering its speed. Hardware fan control knobs function, but with more fine-grained control. Your gaming sessions will be a little more peaceful once you’ve dialed in the right tempo.

Clean out the Dust

When it comes to computers, dust is an unfortunate inevitability. You’ll run into it, as you’ll run into blue screens and dead hard drives. Excess dust means more heat, which means fans must spin faster to keep things cool. So grab a screwdriver, open your computer or laptop, and give it a thorough cleaning with an air duster (or an electric duster, if things are bad). If your fan is making a clicking or other unusual noise, check to see if the blades haven’t collided with a stray power cable or anything similar. If you have a desktop computer, consider installing filters on your intake fans to avoid potential dust accumulation.

Replace a Loud (or Failing) Fan entirely

If none of the above suggestions work, one (or more) of your fans can need to be replaced. Even if a fan is in good working order, it may be too noisy at times. If your CPU heatsink is small, replace it with a larger one. The larger fan will not only be quieter, but the increased surface area of the fins will better dissipate heat.

A clicking, ringing, or grinding noise can also be heard as a result of this. You will save your PC from sounding like a jet engine a few years down the road by using the right fan and doing some preventative maintenance.

How can I make my computer fan quieter?

There’s one major explanation why your Windows PC sounds like a jet engine: loud fans. Fans can seem unimportant, but they are critical PC components that must be maintained. Unless you’re using water cooling, you’ll need your PC fans to keep components like your CPU cool enough to keep them running.

Dust, dirt, and other pollutants in the air may affect the efficiency of your fan, but other issues can arise. If your computer fans are becoming too noisy, try these six troubleshooting tips to resolve the problem.

Give your PC fans a clean

When your fans pull air into your PC or laptop case, they also carry in other pollutants. Your computer fans will get louder if you don’t give them a complete clean now and then, much as a bookcase will if you don’t scrub and polish it now and then.

This is easier to do on a desktop PC, where removing the side panel and gaining access to your fans for cleaning is an easy operation. Keep a screwdriver ready since most case panels are held in place by a few screws. The method is a bit more difficult with laptops.

If you’re comfortable disassembling your laptop, this will allow you complete access to clean your fans. You may use an air duster, compressed air, or a special electric air duster vacuum to clear dust from your PC or laptop.

Your fans should have to work a little less hard to cool your machine now that the dust has been removed, resulting in a quieter PC overall.

Move your PC or Laptop for better airflow

It’s important to consider where you put your computer or laptop because it can affect whether your computer fans have enough airflow to keep your machine cool. You won’t put your PC fans near a heater or radiator, but you might put them in a desk cupboard with the fans in the back.

This is bad for your PC because it restricts the amount of air available to your fans, causing the air around it to heat up. Hotter air means a hotter machine, which means your fans will have to work harder to keep your computer cool, resulting in louder computer fans. A laptop mounted on surfaces that can obstruct your fans follows the same rule.

Allow enough air for your desktop PC or laptop fans to do their job, and you should notice a cooler machine (as well as quieter fans).

Laptop Users: Use a Laptop cooling pad

You can not have as much access to your fans on a laptop as you would on a desktop PC if you have fan problems. If you’re afraid of taking your laptop apart, there are several alternatives, like using an external laptop cooling pad.

A laptop cooling pad is a collection of external fans that you can put on top of your laptop to draw heat away from the motherboard and direct it underneath the laptop. It lifts your laptop, allowing enough airflow underneath it for your fans to cool it.

If you don’t want to deal with more serious repairs, this is a good way to keep your laptop cool.

Check Running Software

When your PC is running the most demanding programs, the computer fans kick in the most. If your computer fans are noisy even when your computer is turned off, it may be a sign of a software or malware issue.

Some malware (such as crypto miners) can, for example, use your idle PC for other purposes. Since you may not be aware of an infection, it’s important to search your Windows PC for malware.

If malware isn’t the issue, use the Windows Task Manager to look for any running processes by pressing Ctrl + Shift + Esc on your keyboard. You’ll find a list of active apps and background processes, as well as any resource use, in the Processes section.

If your CPU or memory percentages are stuck at 100%, your machine is in overdrive. You’ll need to interrupt, disable, or uninstall any overactive apps that are causing the issue.

Use Fan Control Software

You may use third-party fan control software to reduce the speed of your computer fans if they are too noisy. However, if your PC is overheating and your fans aren’t working, this isn’t a good idea, as a computer or laptop that is too hot can be harmed.

Some motherboard manufacturers, such as MSI, have their fan control software, but SpeedFan is a decent third-party app for Windows users. This app will show you your current PC temperatures and allow you to adjust your fan speeds based on your device’s requirements.

If you plan to slow down your fans, keep an eye on your computer’s temperature. If the temperatures continue to rise, you’ll need to revert to the previous settings to ensure that your fans will cool your PC.

Replace Your Fans

If you plan to slow down your fans, keep an eye on your computer’s temperature. If the temperatures continue to rise, you’ll need to revert to the previous settings to ensure that your fans will cool your PC.

The ball bearings used to transform the blades of older PC fans are one source of failure. These lose their lubrication over time, leading to the computer making buzzing noise.

Desktop PC fans, are easy to replace because they use standard sizing and plug into your motherboard or power supply. Laptop fans are more difficult to replace because they are made exclusively for some laptops to suit the smaller casing.

Also, keep in mind your warranty: If you are having laptop fan noise and your laptop is already under warranty, you might be able to get a free laptop fan replacement.

Regular Windows PC maintenance

Dust and dirt are the most common causes of a noisy computer fan, so break out the compressed air cans and clean your PC or laptop as part of your daily PC maintenance routine. Computer making noise is overworked fans, which can affect your PC’s overall performance.

Of course, the computer’s fans aren’t the only source of the noise. Components like your hard drive, particularly if it’s failing, are likely to be the source of other whirring fans making noise. Your PC won’t last indefinitely without any TLC, but with a little TLC now and then, it can last for several years.

Why is my computer fan so loud all of a sudden?

The fan is probably the loudest part of your machine, and this is amplified as the computer spins faster to dissipate more heat. However, if you hear a sudden rise in the volume of your computer’s voice, it may be due to program adjustments or something affecting the computer’s hardware. As a result, why is my computer fan loud but not hot?

If by loudly you mean a rise in the number of revolutions per minute, the main cause may be a defective heat sensor or heat. As a result, you should keep an eye on your memory, CPU, and disc use to see if the shift in fan speed is related to either of them. Restricted airflow, a dirty heat sink, and ambient temperatures may all contribute to this.

If there isn’t a noticeable temperature difference, it may be due to a defective fan control sensor. Furthermore, it may be the product of worn bearings, in which case the fan should be replaced. You may remove the sticker to reveal an opening for lubricant.

What could be the cause of this condition?

There may be two main explanations for your computer fan to sound like it’s running at a higher speed the majority of the time or laptop fan making noise.

  • It may be the result of a background process that causes the machine to become hotter. In this situation, it’s ideal if you know how to reach your monitor, which is normally built-in.
  • The second explanation may be that it is filthy, especially in situations where the machine is exposed to filth. You may need to open up your computer to clean it in this case.

The following is a list of potential reasons for the irritating noise coming from your computer:

The software angle

When you make changes to your operating system or install software that runs in the background, you can experience a case of system overload. When you put too much strain on your machine, it becomes overheated, causing the fan to work harder. As a result, you must pay attention to what you’re doing before the fan begins making a loud noise.

Blocked vents and dirty fans

The older a machine gets, the more it overheats, particularly if the vents aren’t cleaned. It may also be a function of how you use the machine. Placing your machine on your lap or a flat surface can block the air vents, resulting in reduced airflow and faster fan rotation.

Hard disk failure

It’s also possible that the noise is coming from an imminent hard drive malfunction rather than the fan. If you hear a whirring noise near your hard drive, for example, you may need to back up your files. When a mechanical part inside an HDD begins to fail, the hard drive can become noisier. When faced with this scenario, the safest course of action is to back up the data while the hard drive is being replaced.

Tips to help you fix the loud noise from your computer

You’re aware that a noisy and consistent noise coming from your machine may be the product of a malfunctioning fan. Other factors may include the processor and graphics card. When a computer generates too much heat, the computer can become damaged. If you want to solve your fan’s noise problem, follow these simple steps:

Clean the computer’s fans

Cleaning your computer’s fans could take up to 30 minutes. When working with a tablet or laptop, this time is shorter; but, when working with a desktop computer, it takes longer. Cleaning the CPU fan, as well as the graphics card fan and any other fans, will be the first move. In the case of tablets and laptops, the CPU and other components may or may not be cooled by a fan.

If you’re having trouble determining which panels should be removed to gain access to the fan and CPU, you might need to consult your computer’s manual online. In the case of a laptop, however, the chances of your machine having both a CPU and GPU fan are very high.

Cleaning the power fan, as well as any other fans, is the second move. If you have a tablet or a laptop, the odds are that you only have one fan. In this case, avoid blowing the dust back into your computer, as this could amplify the noise produced by the computer.

As a result, blowing the air created by the fan at an angle is recommended. This will assist in blowing the dust away from the fan grates. Desktop computers usually have a power supply fan and, as a result, do not have outflow and inflow case fans. You can use the fans on both the inside and outside of the house until no more dust is visible.

If the fan still does not move after you’ve followed the above steps, you will need to replace it. But, make sure the fan is plugged into the motherboard for the power supply before proceeding.

What can I do to ensure that my computer does not get hot?

This means that despite the fans running at full speed, your machine is still hot. When this occurs, it means that they are unable to cool the hardware enough to slow it down, resulting in the noise.

Here are a few helpful hints for keeping your machine cool:

  • Continuous airflow

This is the simplest and most efficient way to keep your machine from overheating. In this case, what you need to do is give your machine some extra breathing room while also removing any barriers to airflow. Often, make sure nothing is blocking the computer’s sides.

  • Move your computer

The area where your machine is located may be dirty or hot. The best course of action, in this case, is to relocate the machine. This might imply removing the machine from the room.

  • Get a case fan

A case fan is a small fan that is connected from the inside to the back or front of a computer case. They are very effective at moving air inside the device, which is the best way to keep the computer’s critical components cool. Installing two case fans is one way to keep your machine cool all the time. Case fans are usually much easier to install than CPU fans.

  • Get an upgrade of the CPU fan

Any expert can tell you that the CPU is likely the most costly and delicate component in your machine. Furthermore, it has the greatest risk of overheating. Unless you’ve recently replaced it, the fan in your CPU is most likely one of those that do enough to keep it running. Several companies offer big CPU fans that can hold the CPU temperature much lower than the built-in fans.

  • Quit overlocking

If you don’t know what overclocking is, it’s safe to assume you don’t do it. Overlocking is a technique for pushing the machine to its limits. However, the temperature of the system is affected by the changes made during this process. It is dangerous to overclock your device without taking the necessary precautions to ensure that the hardware is cool. You may have to revert to factory default settings.

Conclusion

It’s important to emphasize that the way you handle your machine affects its overall health and well-being. Something is wrong with your machine if it begins making a loud noise. In this case, you’ll need to follow the advice and guidance given in this post.
