Why Does My Computer Sound Like a Jet Engine? No More Noises

Any electronic devices have the tendency to make noise with time and use. A common device we complain about is our very own computer. We all come to that point where we have wondered, “why does my computer sound like a jet engine?”

If you have the same question in mind, you’re at the right place. The computers will normally sound like a jet engine taking off when there are issues with the hard drive, the cooling fan, the power supply, or any other hardware inside the system unit. Let us dive into the article to find out more about this.

Why is My Computer Making So Much Noise?

Why is your computer making so much noise? It is because of some underlying problem with the hardware or a component of your system unit. The problem can be in the cooling fan.

When the cooling fan is collected with a lot of dust, hair, or other tints, the fan has to work even harder to exhaust heat to keep the system cool.

Sometimes the wear and tear of the blades make weird noises too. If the fan isn’t the problem, look for the noise in the hard disk because when the HDD is processing data, the head spins, making a low-key vibrating noise.

In addition, other uncommon parts include the processor that heats quickly due to faults, loose parts, or a damaged power supply and motor.

How Loud Should a PC Be?

It is pretty normal for a computer to make noise, as long as it isn’t too loud and unusual.

If your computer is making noise as loud as 30 to 50 dB (A), it isn’t a problem at all. It is the standard level of noise in the system.

If the noise level exceeds the point, it vibrates loud, screeching, or like a jet engine that, causes annoyance. You have a problem to solve.

Is It Normal for a Computer to Be Loud?

It is totally normal for a computer to make noise, but not too loud enough to be a concern. Suppose the noise is so loud that it distracts you from doing your tasks. It may be time to give the system a check.

The noise can be due to a broken, clogged, loose, or damaged fan. Or it can be that your computer is overused, with the power supply and processor acting up on excessive heat production. Try shutting down the PC for some time and check again if the noise still persists. If it does, you better take a look at the hardware components. Sometimes the speakers make weird noises too when not working properly.

How Can I Identify Which Component is Causing the Noise Inside the Computer?

If you have a hard time finding out which component is making noise, look into the following components and the nature of noise produced in normal circumstances and abnormal circumstances. The computer produces many kinds of noise over the period of use.

If the sound you hear is somewhat like a pattern, with long beeps or simple, quick noises, it is an indication of a problem inside the PC.

If the noise produced is external and persists the whole time your computer is on, it might be a hardware issue. For example:

  • Power Supply Issues: when the power supply produces noise that is more than the usual humming, there is a problem with the power supply or its fan. There may be dust, dirt, lint, or hair stuck in the supply and the fan blades. Clean the power supply and check for the noise again. If the noise still persists, replace it with a new one.
  • The System Fans: there are three main fans in the system. If the case fan is damaged, it will produce a loud pitch or a click when operating. This is an indication of loose blades or damage in the fan. If the noise is a loud vibration that persists as long as the PC is on, it can be the heat sink or processor fan. The issue can be a broken, damaged, loose, or clogged fan. The third one is the power supply fan we mentioned above.
  • Hard Drive or Disk: if the noise coming from the system unit is a loud thud, click, or knock, it usually is the hard drive. It may indicate that it’s time to clean or replace it.
  • Speakers and Monitor: if the noise produced is a loud popping or cracking sound, it could be the speaker turning on.

How Can We Fix the Noise Issue Caused by a Computer Fan?

A noisy fan is an annoying and disturbing problem., especially if the noise is continued as long as the PC is on.

We use these fans for ventilation and for cooling the system at times of rise in internal temperature.

The fan is an important part of the PC. It promotes the longevity of the hardware inside.

Suppose the noise is too obvious from the fans. It can be due to clogging by dirt, dust, hair, or other lint and threads.

The simplest form of getting rid of the noise is by cleaning the fan. Check and remove the dust and dirt clogging it.

The fan will reduce its noise to a hum. If it is a rattling noise, it can be a broken or loose blade that needs to be removed and replaced to work properly.

How Can We Fix the Noise Issue Caused by a Hard Drive

How Can We Fix the Noise Issue Caused by a Hard Drive?

You can fix the noise coming from the hard drive by first backing up all your important files to a USB. Then try to defragment the disk, update the windows or use a built-in check software (windows +R) or do a CHKDSK (windows + X) to check and eliminate the noise.

Sometimes the noise can be due to a damaged PCB, read/write head, disk platter, other dislodges, or physical damages.

In that case, you will have to remove the hard disk drive and replace it with a new one. You can also try fixing it with the help of an expert before buying a new one.

Do More Fans Make your PC Quieter?

Having more fans doesn’t reduce the noise. In fact, it will only increase the noise. The more fans more noise produced. We already have three fans in the PC that hum and vibrate.

Adding extra fans will be a benefit for cooling and ventilation, but the noise level will not be reduced.
