How Can You Prevent a Laptop from Abnormal Fan Noise and Overheating:

Note: If you’re really serious about quietening your computing experience, you might also want to have a look at some of the quietest keyboards you can buy without burning a hole in your wallet.

1. Fix Internal Cooling

Firstly, you should check the temperature of your device. There is no possibility of doing this physically, but you can use an application do measure the temperature of your laptop. You can use Core Temp to do so. After checking the temperature you can start the process to cool your laptop.

Use Compressed Air

You can use either the canned air of an air compressor. When you open up your laptop from the back, you will find a big fan. This is usually where all the dust is accumulated. This dust is the real culprit. you can use canned air to clean the dust and further clean it with a microfiber cloth. This will clear the dust and thus reduce the noise to a large extent.

It is common to have these fan issues on laptops, so it is recommended to clean the dust off your laptop whenever you listen to even a slight buzz of the fan’s noise.

Invest in a Laptop Cooling Pad

A cooling pad is like a sheet that is kept under your laptop. It is built with material that externally cools the temperature of the laptop down to normal. You can choose between laptop coolers that have cooling baseplates and those that are clipped on the laptop to directly zap or suck out the hot air.

Use A Cooling Stand

Any elevated object can do the trick when it comes to acting as a cooling stand. If nothing, you can buy one.

A cooling stand will let the air from the fan go outside instead of hitting a carpet or a table. This will reduce overheating to a great extent.

2. Use Thermal Paste

What is Thermal Paste and what does it do?

Thermal paste is a very high heat conductive paste that is used between two objects (usually a heatsink and a CPU/GPU) to get better heat conduction. It will reduce the noise almost completely and prevents the CPU from heating. Many users have guaranteed that thermal paste replacement always helps. It not only reduces the noise, but the device also starts working better.

Here’s more information on how to use a thermal paste.

3. Get Rid Of That Dust

Dust is usually the main reason to create all the trouble with loud fan noise. Since it is complicated to open or disassemble a laptop, most people don’t open it. Most times, the dust is collected in the fan blades, You can clean the fan blades and make them dust-free using the following steps:

  1. Shut down your laptop and disconnect electricity
  2. Flip it to the backside and remove its battery
  3. You will find an air vent on the outer edge
  4. Unscrew that panel and open it up
  5. Now, you can see the fan underneath it
  6. The only thing that you need to do now is to blow out the dust. Preferably, you should do it outside because there is a lot of dust accumulated. Use another fan (for example, for your hair) to blow it even more
  7. Once the dust is cleaned, you can close the panel
  8. Try switching on the laptop after 15-30 minutes

4. Use A Mixture Of Methods

You can try different methods together- clean unnecessary tasks, change system settings, use a cooling pad, use an anti-virus, etc. These will help the system to cool down and work better.

5. Change System Settings

Go to the settings and click on the power and sleep settings. Further, choose “Additional power settings”.

After that, a dialogue box will appear. Choose “Change plan settings”.

Click on “Change advanced power settings”

Lastly, when this dialogue box below appears, click on “Processor power management”->”System cooling policy”–>Click to “Passive”.

This will cool down the fan and slow it down.

6. Seek and Destroy Malware

Its common knowledge that viruses and malware slow down the system of the laptop or PC. This leads to increasing problems with your laptop. It slows down your PC and makes your laptop inefficient. Not only will the malware not let your commands be completed properly, but it will also raise the temperature of the laptop.

7. Kill Unnecessary Tasks

For most of the working individuals, it’s not unusual to have too many opened procedures, tabs, and projects that they aren’t utilizing.

These procedures are taking a specific piece of your processor and smash memory too. They make the processor slow.

In spite of the fact that they are out of sight, they take an immense piece of your laptop’s memory and the effort to run them effectively.

What Does Your Laptop Fan Do?

The fan is the loudest part of your laptop. When you are using your laptop, it needs to dissipate heat, it does that by blowing out air. the job of the fan is to blow that heated air out of the laptop. It is possible that sometimes the fan may spin faster than usual, especially when you are using the GPU (Graphics Processing Unit).

When you hear noise coming from your laptop, first, inspect and find the source of the noise. If it is a loud whirring sound, it’s the fan. If it is a rattling noise, it can be some small loose parts that may have been dismantled.

Common Causes for Abnormal or Loud Fan Noise & Overheating:

1. Fans or Air Vents That Are Obstructed

Blocked air vents can cause genuine execution issues by limiting airflow, this can cause the processor, memory (RAM) and other equipment to overheat which may prompt potential hardware failure. This will, in turn, lead to overheating which will increase the fan’s spins and lead to a loud noise created by the fan.

2. Residue Collection on Vents or Fans

An accumulation of dust particles on the vents or fans will lead to blockage and prevent the proper passage of air. It is important that your laptop doesn’t have dust accumulated inside it to keep it over excessive heating.

3. Not Enough Ventilation

A laptop that doesn’t get enough ventilation will have a lower life span and also will work inefficiently. Adequate ventilation will keep the laptop from overheating and give better results.

4. Physical Damage

If a laptop is broken or has a part of it broken, it may ruin the whole laptop. The systems will slow down and will reduce performance to a huge extent.

5. Out-of-date BIOS

BIOS (basic input/output system) is the program a personal computer’s microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer’s operating system and attached devices such as the hard disk, video adapter, keyboard, mouse, and printer.

If the BIOS is out of date, it may slow down the laptop causing the laptop to overheat and thus increase the spinning- causing all the noise.

*Dell recommends updating the device drivers and BIOS as part of your scheduled update cycle.

Can It Be a Hardware Problem?

When was the last time you defragged your laptop?

If you have Windows 8 and 8.1, it’s done for you automatically. A lot of times the files you delete, switch around to new folders and change the names of leaving little traces of “original versions” behind. These bits and bobs of left-behind traces add up over time. Defragging your laptop will get rid of these tiny cache bits and pieces and will refresh your computer, making its software organized and in-line.

Defragging your computer once a month or so will give you the best results. Your laptop will run smoother and more efficiently than ever.

What is defragmentation?

Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file. If you don’t know what defragmentation is, in simple words- it is like a full-body cleaning of the laptop! Just like we keep our homes clean by dusting, defragging a PC keeps it clean.

What If It Is a Software Issue?

Software related problems might sometimes create that weird noise from your laptop. If an update is released and it’s not well optimized, it may put some stress on your laptop. This will lead to the heating of the device- increasing the fan speed.

Installing the latest patches may help you fix abnormal fan noise issues.

Which One Is Good for You: SSD or HDD?

Solid State Drives (SSDs) are storage devices that make use of integrated electrical circuits to store data. Also known as flash drives or solid-state disks. Hard Disk Drives have mechanical parts that move, unlike solid-state drives that are completely devoid of moving parts. On top of that, HDDs take up more space and make a lot of noise when they are working.

Since SSDs have better storage, are noise-free they are an obviously better option than HDDs. Although, SSDs may be a little pricey than the normal, cheap HDDs. Analyze your problem and decide if SSD is better for you or HDD.

What You Need to Know About Laptop Fan Noise: FAQs

What Happens If the Fan in the Laptop Stops Working?

If the fan in your laptop stops working, it may lead to damage to the processing unit and the laptop will get overheated in seconds. The laptop may get completely damaged too. If the fan in your computer stops even for a couple of minutes you’ll smoke coming out of your laptop and the screen goes blank in no time. It can lead to the whole desktop to be in ashes in a matter of minutes. This happens because your processor processes billions of cycles in a second, which results in generating a considerable amount of heat. It is a common problem in laptops and PCs. If the fan stops working you should get it repaired immediately.

Can a Laptop Function Without a Fan?

The more you use a laptop without a fan, the more heated it will get. It is not recommended to use a laptop without a cooling fan. You may totally kill your laptop if you do so.

My Laptop Fan Is Making Noise but It’s Not Overheating. What Could Be the Problem?

If the laptop is not overheating but is creating noise, there is a possibility that BIOS is not up-to-date. Another possibility could be that there is a little dust accumulated in the fan which is creating a buzz- but it is not enough for blockage and thus for overheating.

Fixing the Loud Laptop Fan Noise

Weird fan noises coming out of your laptop are not a new problem. These might indicate that something is wrong within the system. These problems can be detected and solved easily.

First, you need to identify where the chaos is creating- if its the fan or just some loose parts.

The noise made by the fan is usually because of dust. Once you follow the procedures and get rid of the dust, you will notice a remarkable decrease in the sound. If you are afraid of opening up your PC, you can always use external solutions- like, use a cooling pad or kill some unused processes.

Hybrids like Microsoft’s Surface range and the iPad Pro generate heat but use more efficient (and less powerful chips). So it always recommended using a cooler or a cooling stand. Another effective option is using the thermal paste- very effective.
