Stop The Hungry Possessing Apps

When your PC starts making loud noise from the fans, check any software issues before opening the hood for a hardware check-up. It implies whether you’re having any software issues like overconsumption of CPU.

The CPU’s sole purpose indeed is to control all the programs on your computer. But sometimes, a few software tends to consume a large portion of your disk without any reason, such as OS updates, module installer, etc. 

These programs are naturally processor and disk hungry and tend to make the processor busy. Thus making the computer fan rotate faster, which makes it noisy.

In such cases, you can shut down the programs from the task manager. After that, you’ll see your PC/laptop fan’s rotations are back to normal, and the noise is quieter now.

Clean The PC Thoroughly

If the earlier tip didn’t work, then it’s a hardware issue. One particular issue is dust accumulation on your computer fan. First thing you should know, if you clean your PC once a week, dust won’t be able to build up over the computer fans. 

As it happens, you didn’t, and your computer fans are dusty. For such reason, it’s hard for the fans to rotate properly, thus making noise. An easy way to clean those dusty fans is to use an air compressor. With an air compressor, you’ll be able to clear out all the dirt from the fans with ease.   

Clear Out The Air Vents & Heat Sinks

Your PC and laptop manufacturers provide an air vent and heat sinks to maintain the proper airflow, which helps reduce the heat it generates while running.

If you don’t keep them clean, the heat and air won’t be able to flow in their natural order. If the heat build-up inside your pc, your fans have to work harder, which means making a lot of noise.

Clean those air vents, and heat sinks regularly so that your computer fans don’t make any loud sound while rotating. 

Use A Software or BIOS To Control The Fans

To reduce your computer fan’s loud noise, you can use exterior software to control their usage. With this software, you’ll be able to control the fan’s speed and which section to focus on cooling.

Some PC/laptops have the fan controlling software in-build with BIOS. It allows you to control the computer fans for the BIOS settings. You can enter the BIOS function by pressing the delete key several times while your PC is starting. Sometimes for different motherboard systems, you need to press F12. 

You’ll need the fan controlling software, especially when your PC doesn’t have any other cooling system like water-cooling.

Replace Faulty Fans

Despite how good the machines are, every device gives out with time. Yes, with good maintenance, your product can last longer than its usual time. But eventually, it’ll break.

The computer fans are not any different, and it’s a fact faulty fans will make a loud noise. In such cases, replacing the old fans with new ones is the ideal choice.

Provide A better Air Flow

PC/Laptop placement is also a factor in making the fans noisy. As you know, your computer’s fans don’t produce air by themselves; instead, they suck the surrounding air inwards from your computer. So, a cooler environment helps your computer fan to provide cold air to the PC and vice-versa.

Limited airflow is not ideal for your computer. The limited ventilation makes your computer heats up quickly. Thus, making your PC/laptop’s fan work faster than its usual rate, following up with making a loud noise.    

Last Words
