How To Quiet Computer Fans In Accurate Ways

If your Windows computer making noise like a fighter jet, it’s most likely due to its noisy fan. Fans may appear minor, yet they are critical PC elements that must be serviced regularly. Unless you use a liquid cooling system, you require your computer fans to take heat away from parts like the CPU to maintain them running. Therefore, you need to know how to quiet computer fans in the right ways to keep your PC running well all the time dirt, grime, and other pollutants in the air can affect the function of your fan, but other issues might arise, and that is why routine servicing is necessary. 

If your computer fans are becoming too noisy, here are six troubleshooting methods you may attempt to resolve the issue.

Introduction To The PC Fans

A computer fan is an equipment that circulates air to and from a computer or components to maintain the laptop or device cooler.

How To Quiet Computer Fans In Accurate Ways

A fan’s rate is given in revolutions per minute (RPM), and the greater the RPM number, the quicker the fan rotates. In many situations, nevertheless, the greater the RPM limit, the noisier the fan.

The list consists of the many types of fans found within a computer and the computer hardware parts that need fans to work effectively.

  • A case fan is a fan located on the computer case’s side, within the case. It aids in the circulation of air within the patient and the removal of hotter air from it.
  • A CPU fan is a fan that sits on top of a computer processor. It draws and blows heated air away from the CPU, keeping it cooler.
  • A power supply fan is a fan that is positioned within a power source. These electrical power fans exhaust hotter air from the power source and the computer.
  • A video card fan is a fan attached to a DVD drive. It prevents more powerful video cards from overheating, especially while playing video games, editing movies, and performing any GPU and graphics-intensive chores.

What’s The Deal With The PC Fan Being So Loud?

A noisy fan occurs whenever your computer generates lots of heat, causing your laptop’s fans to go into action, driving heated air off your PC and allowing cool air to come in. Laptop fan loud could also be triggered by dust accumulation in your PC, which reduces its performance.

In the computer lies a plethora of complex gear, including the CPU, power source, graphics card, and other components. All of them create a lot of heat. High temperatures are also dangerous to the sensitive electrical components inside your computer. To maintain heat levels in check, the fans within your laptop begin to spin, pushing hot air out and cooling away your PC.

While performing demanding tasks on the computer, including playing online games, editing big multimedia files, or running a CPU test program, it is common to hear noisy computer fans. This isn’t always a cause for concern as long as they settle down once you’re done. However, if you hear a lot of fan noise from your desktop computer under typical conditions, keep reading to figure out what’s wrong.

Your computer fan may be working overtime for a variety of reasons, including:

  • Your ceiling fans are filthy. Dust accumulates within your computer, particularly if you have a large desktop PC. When dust accumulates on your computer fans, they no longer function properly. Laptop fan noise is frequently caused by dust as well as other debris.
  • Your PC is incapable of dissipating heat. The term “laptop” is deceptive since when you sit on the lap, your legs simultaneously send heat to the computer and restrict cold air from flowing through to cool it down. Desktop PCs require access to cool air as well.
  • Your fans aren’t turning on. Moving components deteriorate with time and finally fail. Fans on desktops and laptops that are operating too loudly could be faulty. There could be a problem with the software for the hardware component that is powering the erroneous fan.
  • Your CPU is running too hard. Sometimes that’s not even a fan issue. If software consumes far above its fair portion of your CPU’s capabilities, your machine will quickly heat up. A quiet PC fan producing noise out of nowhere may signal a problem with high CPU utilization.

Step By Step Guideline To Quiet Computer Fans

Here is a detailed guide of 5 steps to make your computer fan quieter:

Examine The Software Running

Before you go for a screwdriver:

  1. Investigate what program is presently operating, what resource it is consuming, and if that fan sound is necessary.
  2. Open the Task Manager on a Windows system, press Ctrl+Shift+Esc and then select the More Details option.
  3. On a Mac, use Ctrl+Space and look for Activity Monitor.

It might be beneficial to download a tool such as Core Temp for Windows and Temp Monitor for Mac to determine whether your CPU has become overheated.

If you’re not doing anything demanding right now, your CPU use in Task Manager should be modest, about 20%. If your PC is inactive and the CPU uses all of its power, check via the list to discover what software is consuming those cycles. Perhaps you have something operating in the back which you are unaware of, or you’ve been hacked that is destroying your PC’s capabilities with no awareness.

If a fan sound only appears if you’re doing anything heavy, such as playing or downloading a huge video file, this is the expected behavior, and that it’s the right time to take a closer check at its hardware.

Allow Your PC To Breathe

Blade Runner has not yet become a reality. Your machine does not truly “breathe” like a human. However, if there isn’t enough space for air to circulate your PC, it will become hotter than required, requiring your fans to spin at full speed to cool it down. Don’t place your computer on top of a cushion or any soft surface. They will obstruct the vents that enable air to move in and out of the machine. Lap desks are a far superior option.

And for the love of everything sacred, please do not cover the computer with the blanket. You might gawk, but someone did this since ” its lights were just too harsh.” Anything that restricts airflow can cause your computer to overheat, forcing your fan to spin faster and faster to attain desired temperatures.

Configure Fan Control

Several PCs have their fans running at full speed all of the time. This is frequent when you built your personal computer and did not fine-tune the cooling gear. Whether the fans are connected to a motherboard of the computer, you may manage them through the BIOS. When your computer boots, hit a key, generally DEL, F2, or something similar, to access the BIOS panel. Next, check for the chapter on hardware monitors or similar things.

Because each BIOS is unique, we can’t guide you via precise procedures. Some will give simple “high” and “low” fan settings, whereas others may include sophisticated fan curves that allow you to control the fan’s speed at various CPU temps. Certain motherboards may handle all attached fans, whereas others may have only managed fans with 4-pin PWM converters rather than the cheap 3-pin fan models. Experiment only with the fan settings tab to find what works best for you.

If your BIOS lacks fan control choices, software like SpeedFan will work as well, but only until the motherboard is technically capable of handling those fans. MSI Afterburner for graphics processors might let you modify the fan’s behavior during a heavy play session.

Various hardware attachments can assist if you cannot manage the fans via software, for example, when the fans are hooked directly into the power source instead of into the board. Noctua manufactures low-noise adapters that function effectively as a resistor, lowering the power delivered to the fan and therefore lowering its speed. Hardware control panel knobs provide a similar function but provide more excellent fine-grained manipulation. Once you’ve dialed in at the proper place, your playing experiences should be a little more tranquil.

Get Rid of the Dust

Whenever it comes to PCs, dust seems like one of those unpleasant inevitabilities that make your computer fan loud but not hot much. You’ll run across it at some time, just like blue screens or dead hard disks. Excess dust equals heat energy, which requires fans to spin quickly to keep things settled, and the issue may get very serious if you are smoking or having pets inside your home.

Then take a screwdriver, start opening your desktop or laptop, giving it a thorough once-over with an air duster or, if conditions are nasty, an electric duster. When your fan creates a clicking or some other unusual noise, check to see if the blades aren’t colliding with a stray power wire or anything similar. Lastly, if you’ve got a desktop, try installing filters on the intake fans to avoid further dust accumulation.

Replace A Noisy Or Failing Fan Completely

When none of the previous solutions work, it could be necessary to update one or even more of your fans. Even though a fan has been in good operating order, it might not be quiet at times. Smaller fans are generally louder, so if you have a 90mm loud fan that you can replace with anything more significant or remove entirely without harming temps, start there. If the CPU heatsink is little, replace it with a bigger one. The bigger fan would not only be silent, but really, the greater surface area of the fins will disperse heat better.

Sometimes a fan is on its way to the dusty cemetery. This frequently results in your computer making buzzing noise or crunching noise that is difficult to ignore. You could remedy this by putting a bit of sewing machine oils in the bearings, but it is usually done before symptoms appear. When that doesn’t work, it’s time to replace the fan. When searching, keep an eye out for the “CFM” and “dBA” values in the specifications. The former represents airflow, whereas the latter represents noise intensity. With the appropriate fan and some rust proofing, you could protect your PC from noisy sounds in the next few years.

Frequently Asked Questions About Computer Fans

What Is The Number Of Fans On A Computer?

There is no standard for the number of fans that can be installed on a computer. Most desktop PCs feature at least four fans: CPU heatsink fan, case fan, power supply fan, and video card fan. It also is relatively unusual for PCs to include a second front casing fan to aid with ventilation. A computer, on the other hand, can have no fans if it employs fluid cooling.

Do No-Fan Computers Have Any Harm?

Due to their tiny size, laptop computers generally only feature between modest one to two fans. A laptop with no fans or poor fans might cause several of the hardware to overheat unless it is intended to function without fans. Overheating a component might result in physical damages. Most modern technology turns off or restarts immediately to help avoid injury.

Is It A Problem If My Pc Fan Is Too Loud?

Noisy laptops and computer fans might be an indication of an issue, particularly if the sounds persist for an extended length of time. A quiet computer fans objective is to maintain your system cool, and excess fan sound indicates that they are trying harder than how they ought to.

If your fans are unable to adequately lower the temperature within your computer, you may begin to notice a variety of problems. The CPU may self-regulate its performance in an attempt to reduce energy output, resulting in a significant decrease in quality and efficiency.

When the heat levels of your PC become high, the CPU may shut down to prevent irreparable harm. It’s why your system crashes and displays the dreaded blue screen of death. You may also have issues with your computer’s initialization, including a dark startup display or an unending sequence of reboots.

Final Thought

Here are some more considerations to ponder when purchasing a new computer. You must also keep an ear out for any odd sounds coming from your PC.
