Fans in a laptop play the role of an unsung hero because they work silently to keep the laptop shell cooler and deal with myriads of unknown problems. However, sometimes these unsung heroes start making an obnoxious noise without any apparent cause. 

Usually, the fan becomes louder when it has to spin faster. The dust and multitasking can be the two culprits for the terrible noise produced because it makes fans work harder. 

However, it’s better to pinpoint the exact cause of your louder fan and fix it immediately because it can hamper the working of your laptop.  

Reasons that make a Laptop Fan Loud

It becomes very disgusting when a laptop fan becomes louder than a lawnmower. Repulsive and contemptible noise diverts the concentration of users and urges them to smash down the laptop. The solution to this pressing issue is to figure out the underlying cause of the problem. So here are some causes of the potential factors that make the laptop fan loud.

  1. Dirty or Faulty Fans

Check for the cleanliness of the laptop fans by observing any unusual noise. When dust forms a thick layer on the fan surface, the quantity of air passing through the fan slits gets compromised. That’s why the fans spin faster to dissipate extra heat and become louder than usual. It means that more revolutions per minute will cause louder noise.

As the laptop becomes older, its mechanical parts undergo wear and tear. It means that the fan can become faulty due to aging. Due to excessive spinning, the ball bearings of the fan lose with time, and it produces a scornful sound. The large size of the fan can also be a factor in causing a hue and roar. 

  1. Blocked Vents

In addition to fans, the air vents of laptops also get clogged due to dust particles. Blockage causes poor ventilation and ultimately increases the RPMs. As a result, the fan gets louder. 

  1. Overheating CPU

When the central processing unit (CPU) of a laptop has to work hard, it gets overheated. Different factors contribute to the overheating of the CPU and ultimately to the loudness of the laptop fan. These factors include: 

  • Multitasking. 
  • The dried thermal paste on heatsinks of CPU & GPU. 
  • Faulty hard disk.
  • Poor ventilation.

By sorting out these issues, you can prevent overheating of the CPU. 

  1. Malware 

Malware is the viral software that hijacks your computer and assesses all the data on your drives. Spyware, Trojan horses, and worms fall under the category of malware. Due to a malware attack, the hard disk and memory of the CPU get overloaded and result in overheating. It ultimately puts the Laptop fan on its knees, and it had to work harder to dissipate the extra heat. 

  1. Outdated Drivers

If your installed drives get outdated, the hardware will not work efficiently. It produces an extra load on the laptop and makes it run heavier. The laptop fans will run fast to tackle this situation and ultimately cause a louder voice than actual. 

  1. Multiple background running programs

Sometimes we work with multiple programs on our laptops. Some other programs also get started working in the background during multitasking. All these programs take up extra space on the SSD. So, the over-consumption of memory will ultimately affect the performance of the CPU, which in turn puts a load on the laptop fans.
