Why does my mac sound like a jet engine? (2023)

How do I stop my Mac from making a sound like a jet engine?

Make sure the vents on your Apple product aren't blocked

Some Apple products have vents that let fans bring in cool air and expel hot air. Make sure that the vents aren't blocked to allow your device to perform at its best. Use your device on a hard, flat surface like a table or desk for optimal temperature control.

Your Mac fan may kickstart when you're running intensive tasks or resource-heavy apps that make your Mac overheat. With MacBooks in particular, fan noise can sound as though your Mac wants to take off. By the way, in case of overheating, your Mac usually slows down.

Check your Mac's vents aren't blocked

So if your MacBook is running loudly, try moving it to a hard, flat surface, like a table or desk. With all types of Macs, you should also make sure the vents aren't clogged up with anything. If they are, use a brush to clean them out.

Keep vents clear

These vents draw in cool air and expel hot air. If you block these vents by resting your laptop on a lap, couch cushion, pillow, bed or blanket, then your Mac is sure to heat up quick. I use a coffee table book to keep my MacBook Pro's vents unobstructed when sitting on a couch or lying in bed.

Your computer fan gets loud because of high internal temps caused by 100% disk usage, high RAM usage, dust and dirt in the vents, or lack of airflow. It's normal for your fan to get loud sometimes, but if it makes a loud rattle for a while, you should investigate.

Use compressed air to blast the dust out and clean your iMac fan and iMac air vents. Again, don't use a vacuum because the static electricity can fry the electronic components. Use compressed air only!

Your Macbook's cooling system, including fan and rear vents pull cool air in from the back and (in the case of the Macbook pro) also from the left ports bringing this air around the processor, GPU, and heat sync and blow it out the back, as such your Macbook acts like a little vacuum cleaner of the air around you.

Why is my Mac making a weird sound?

Strange sounds coming from your MacBook Pro's speakers can be caused by damaged or blown speakers, audio settings or a temporary problem that can be resolved by resetting the SMC and PRAM.

If you notice the computer fan running constantly and making an abnormal or loud noise, this might indicate that the computer is not running as efficiently as possible, and/or clogged air vents. It is important to keep dust from accumulating in your computer and ensure adequate ventilation to help reduce heat.

The two biggest culprits for excess noise in computers are fans and the hard disk. Fans are used to move the heat produced by the processor, motherboard, and graphics card out of the computer. If the fans are loose, too small, or not powerful enough, they can create noise.

Put one of your finger in the middle of the fan so it can't turn anymore. Take your brush and gently try to loosen up the dust particles with the bristles of the brush. This might take a while but you'll see that there's quite a lot of dust hidden in that fan. Gently blow the dust away once it's out of the fan.

1. Can a MacBook break from overheating? Yes, overheating can damage sensitive internal parts of your MacBook. However, many built-in safeguards will slow down or shut off your Mac before it overheats.

An overheating Mac is loud, hot to the touch, and often slow or unresponsive. Heat is notoriously bad for computer hardware, so keeping things cool might help prolong the life of your MacBook, iMac, or Mac Pro.

Runaway apps, in other words, are third-party apps that demand more system resources (especially CPUs) than they should. These apps are either poorly developed or caught in a loop, which can drain battery power and CPU resources. When that happens, it's just a matter of time before your MacBook starts overheating.

Poor ventilation

Perhaps the most common cause of laptop overheating is poor ventilation. If you use your laptop on soft surfaces such as pillows, blankets, couches and your lap, you may be inadvertently blocking fan vents and obstructing your laptop's air flow. Solution: Always use your laptop on a hard, flat surface.

Is it bad if my computer fan is loud? Loud computer fans and loud laptop fans can indicate problems, especially if the noise persists for a long period of time. A computer fan's job is to keep your computer cool, and excessive fan noise means they're working harder than they normally need to.

The components inside a computer generate a lot of heat. When the internal temerature of the computer reaches a certain point fans begin blowing to push the hot air out and bring cooler air into the computer. The higher the temperature the harder the fans run.

Why are my fans running so high?

A fan running at high speed means the CPU is hot and trying to cool itself down. It could before several reasons: It's unable to cool due to clogged air vents or failing fans. The computer is legitimately working on something CPU-intensive.

If you see any blockages, the best option is to contact a local Apple Store or an Authorized Apple Service Provider via Genius Bar. However, not every Apple Store may be able to offer cleaning services. Regular MacBook cleaning can help your laptop looking great but also function at its best.

Using a 70 percent isopropyl alcohol wipe, 75 percent ethyl alcohol wipe, or Clorox Disinfecting Wipes, you may gently wipe the hard, nonporous surfaces of your Apple product, such as the display, keyboard, or other exterior surfaces. Don't use products containing bleach or hydrogen peroxide.

Dust is the most common cause of laptop noises. Dust damages your system in various ways including obstructing your laptops fan, which causes it to make loud noises. Your laptop's processor is essentially its brain; hence, we advise that you clean the processor's cooler from time to time.

When a computer fan spins loudly for a long period of time, there might be an issue with a fan, or the computer might be overheating. Adjust the power settings, clean the fan vents, update the graphics driver, and then update the BIOS to help reduce the internal temperature.

CleanMyMac is safe to download and install from the App Store because Apple does not host malicious software. Some CleanMyMac functionalities, however, may not be suitable for beginning users.

Turn on your Mac, then immediately press and hold the D key on your keyboard as your Mac starts up. Release when you see a progress bar or you're asked to choose a language.

How do I know if my Mac speakers are broken?

You can do so by going to System Preferences -> Sound -> Output tab. Then try to switch the balance slider between the right and left speaker. If one of the speakers is clear and the second is rattling, then you'll know which one is likely blown.

Apple says it costs about $600 to replace the speaker because they glued to the top case and can't be replaced individually.

Laptop fans expel air and make a soft to moderate audible sound under normal use. If your laptop's fan is silent, the air near the vents is calm and the laptop is very hot, it's likely that the fan is not working.

Reasons for loud PC fans when they're idle include dust accumulation, poor ventilation, malware attacks, corrupt processes, and incorrect placement. Sometimes, faulty or smaller fans tend to be noisy. Upgrade your PC's software, move the computer, or change some hardware to fix these issues.

Most causes of the Laptop fan running constantly can be traced down to high CPU utilization caused by Windows updates or other applications. When CPU utilization runs high the CPU gets warm and the fan will run to control the thermal temperature of the CPU.

Vacuum the vents with a handheld vac or dusting attachment on a household vacuum cleaner. Blow the dust out of the vents using compressed air (available at most computer and electronics stores). Be careful to angle the air flow away from the computer to ensure you do not blow the dust further into the computer case.

The MacBook Air Retina generation does not include intake vents along the side, and instead includes a single intake vent at one end of the back screen hinge and a single exhaust vent at the other end of the back screen hinge.

However, if you opt for the compressed air option, it will be better to keep the can at an angle of fewer than 45 degrees. This way, you can prevent the dust particles from getting back into the fan. Just clean your Macbook Pro's fan once or twice a year to increase your device's longevity and enhance its performance.

An easy way to clean your fan in your laptop is to remove the cover, blow away loose dust, and wipe the fan blades with a soft cloth.

When your desktop computer sounds like a jet taking off, there are a couple of likely culprits: fans and the hard disk. These components are more likely to be loud if they're older, when wear and tear and dust settles in.

Why does my Mac keep overheating?

MacBooks can overheat for many reasons: software that strains your processor, too many open browser tabs, and setting your device near external heat sources are common reasons why a Mac can get hot. To avoid MacBook overheating, consider what programs you run and where you place your Mac.

Just heard the noise towards the end, it may actually be that you have left a cable or wire in the proximity of the blades of the fan and they are touching either all the time or just occasionally.

1. Remove dust. Dust is the most common cause of laptop noises. Dust damages your system in various ways including obstructing your laptops fan, which causes it to make loud noises.

It might have been knocked loose or there may be an obstruction in the fan. If the hard drive were failing, it would more likely have a clicking sound.

Use compressed air to blast the dust out and clean your iMac fan and iMac air vents. Again, don't use a vacuum because the static electricity can fry the electronic components. Use compressed air only!

So, in answer to the question: How long do Macs last? We'd say five to eight years, but beware that you probably won't be able to replace any faulty parts in a Mac when more than five years has passed since Apple last sold it.
