Laptop Fan Making a Grinding Noise

Chris Campbell01 May 2022

It can be frightening to hear your laptop making a grinding sound when you switch it on, or even after it has been running for some time. Only mechanical moving parts within a laptop, such as cooling fans or disks and drives, could produce this level of noise. The exact part that is creating the noise might indicate a small or big problem, thus you must identify the cause of the noise as quickly as possible. Other indications of the noise include the laptop working slower than normal, freezing, or even crashing.

You must listen carefully to establish where the noise is coming from to figure out which among the components is making the noise. If possible, the laptop casing should be opened for a more precise evaluation.

  • In the case of an optical disc drive, you could just remove the disc fast and listen to whether the noise goes away upon opening.
  • The noise of a hard disk drive is more akin to a harsh ticking or crackling noise. The disk drive might be overheated and dangerous to touch. In this scenario, you need to back up your data as quickly as possible because the disk could fail.
  • The sound of a cooling fan is similar to a loud whirring or mini engine and is produced by a deficiency of oil, dust accumulated on the fan and within the case, the fan aligned improperly, or cables or other things hitting the fan blades.

Why Is My Laptop Fan Making a Grinding Noise?

Whenever it comes to getting work done in your preferred work environment, nothing beats a laptop. However, mobility comes with a price. Because of the small area inside and the high-capacity batteries, heat buildup is frequently an issue.  So why is your laptop fan making a loud, grinding noise?

Fans are included in laptops for one purpose: to disperse heat by moving air. When your fans turn on, it's usually because they are meant to. However, it may be disturbing and, in some situations, rather loud. When under tremendous pressure, even the most costly machine, such as the newest MacBook Pro, sounds just like a drone taking flight.

If the temperature outside is high, your laptop will have to work more to disperse heat, resulting in increased fan noise. Likewise, if the vents are blocked, as is often the case when using the laptop on soft surfaces, the laptop will become heated. Similarly, if you're enjoying a 3D game, utilizing WebGL, or producing video, heat will accumulate. The final cause is the age of your laptop. As the laptop ages, the fan would have to spin faster to handle newer versions of the present apps, which might be a clue that it's time to start budgeting for a new laptop.

Dell Laptop Fan Making Grinding Noise

Excessive heat might force the fans to spin faster and more frequently, possibly damaging internal components and lowering the performance of your Dell laptop. To keep the internal components cool, your laptop may include one or more fans. It is common for a laptop to create a good amount of heat and then become warm to the touch under regular working conditions. Fans that continue to rotate rapidly and generate unusually loud noises could signal a problem, however.

The following are some of the most common causes of fans creating loud, grinding noises:

  • Obstructions to fans or air vents
  • Dust buildup on vents or fans
  • Overheating
  • Physical Damage

Here's how to fix the problem:

Check and Clean Fans and Vents

Blocked fans or vents can cause the CPU, system memory, and other components to overheat, potentially leading to hardware failure. Excessive heat can also result in a considerable drop in performance since most CPUs immediately lower processing speed to counteract heat-related issues. If you observe the laptop fan running consistently and generating an unusual or loud noise, it might mean that the laptop is not functioning as effectively as it could be, and/or that the fans or vents are clogged. To help minimize heat, it is critical to avoid dust from building in your laptop and to maintain appropriate ventilation.

Ventilate Fans Properly

Proper ventilation is essential for improved airflow within and outside the laptop. Good ventilation could help fans function more effectively while also extending their life. When using your laptop, make sure you place it on a flat, firm surface with no obstructions to the bottom and side air vents. It's also best to use the laptop in a cool setting to avoid overheating.

Run Dell’s Support Assistant

Launching a hardware diagnostic test can assist you in identifying hardware-related issues and will provide you with troubleshooting steps to follow so you can resolve the issue. Run Dell's Support Assistant to identify if your laptop has a hardware problem. Dell laptops have both integrated and online diagnostics to help check if your laptop's hardware components are working properly.

Toshiba Laptop Fan Making Grinding Noise

If you've noticed that your laptop's fan making loud, grinding noises, it might be because the fan is revving up or running harder than normal.  Furthermore, although your Toshiba laptop is small, it is susceptible to dust buildup. Clogged dust may wreak havoc on your laptop's system, causing it to run hot and loud.

If your Toshiba fan makes a strange and loud grinding noise when turned on, here are some solutions:

Check the Running Processes and Close Unnecessary and Intensive Programs

When your laptop gets too loud, it can only signify one thing: it is overloaded. Check to see for any running programs which demand your CPU to work harder than normal. Check for processes that are close to operating at 100 percent since they might be the culprit. Open Task Manager and terminate these processes. If everything appears to be in order, then it's the fan itself that needs to be checked.

Clean Laptop Fan

Dust can accumulate and become stuck in your laptop fan, reducing airflow. If this is the case, cleaning the laptop fan would certainly fix the issue. 

Use a Laptop Cooler

Your laptop can only withstand so much heat before it burns out. Using a laptop cooler is recommended if you mainly use your laptop for work or gaming, as the laptop may be running intensively for a lengthy amount of time. You could select between laptop coolers with cooling baseplates or those that attach to the laptop to immediately blast or suck away excess heat.

With a loud laptop fan, you can't concentrate on what you're working on. A loud laptop fan is generally caused by one of two things: dust or overheating. If you've been hearing loud, grinding noises from your laptop and they're becoming a distraction, it's time to put a stop to it. Follow these tips and you'll have your laptop running smoothly without strange noises in no time.
