Why is MacBook Pro Fan Loud: Causes, Solution to Solve the Problem

macbook pro fan loud

MacBook pro fan loud? If your device’s processor is working on intensive tasks—such as compressing HD video, playing a graphics-heavy game, or indexing the hard drive with Spotlight after you migrate data—the fans run faster to provide additional airflow. You might hear fan noise when this happens, especially if you’re in a quiet environment.

About MacBook Pro Fan Loud and Fan Noise 

Learn how your Apple product monitors internal temperatures and uses fans to cool critical components.

Some Apple products contain sensors that respond when they detect temperature changes inside your system or device, turning on fans to bring cooling airflow to critical components.

About Fan Noise

If your device’s processor is working on intensive tasks—such as compressing HD video, playing a graphics-heavy game, or indexing the hard drive with Spotlight after you migrate data—the fans run faster to provide additional airflow. You might hear fan noise when this happens, especially if you’re in a quiet environment. Macbook pro fan loud. This rushing-air sound is a normal part of the cooling process.

Ambient temperature, the temperature outside the device, also plays a role in the fans’ responsiveness. If the ambient temperature is high, the fans turn on sooner and run faster. 

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. If you use your device on a soft surface like a couch, pillow, bed, or your lap, its fans might run more.

Check for unexpected heavy fan use

If the fans in your device run fast even when it isn’t experiencing heavy usage and is properly ventilated, follow the steps for your device:

Check your apps and tabs

The more apps and browser tabs you’ve got running, the greater the odds are that your Mac will need to employ its fan to keep things cool. Cut down on your multitasking by closing apps when you are done using them, especially when you are using graphics-intensive apps like Photoshop and iMovie.

To see which apps are using the most CPU resources, open the Activity Monitor and click on the CPU tab. In my experience, Chrome is more of a resource hog than Safari, so you might try switching browsers for a quieter Web browsing experience. I also use my iPhone to play music and podcasts with iTunes and Spotify instead of keeping those apps running on my MacBook Pro.

 

Keep vents clear

The MacBook Pro has vents on its sides and back edge, and the MacBook Air has vents along its back edge. 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.

If it looks like a bunch of grime has collected along the vents, you can try blowing it away with a can of compressed air. Of course, you run the risk of just blowing the debris further into your Mac. If that appears to be the case, then you will need to open up your Mac to get under the hood.

Open up and clean

Get yourself a tiny Phillips-head screwdriver and you can remove the bottom panel of your MacBook to clean out any dirt, dust and grime that may have collected over the years. Use your can of compressed air to blow away any debris or a lint-free cloth to wipe it away. Pay particular attention to the cooling fan itself and its vents, along with the entire back edge of your MacBook. The goal here is clean passageways for maximum airflow.

Test your fans

There is a chance that the reason your MacBook is overheating is there’s something wrong with the cooling fan itself. Baked into your Mac is a hardware diagnostic tool. If it was made prior to June 2013, you’ll use the Apple hardware test. After that date, you’ll use Apple Diagonistic. These tools operate in a similar fashion. With your MacBook plugged in and all external peripherals removed, restart it and hold down the D key to start either diagnostic program.

Follow the onscreen instructions to start the test. The standard test takes only a minute or two to complete and will report any hardware issues. For a more thorough investigation, you can check a box to run an extended test that will take an hour or more to complete.

Check out this Apple page of reference codes that may appear in the Test Results section after the test completes. There are three codes, all starting with “PPF,” related to the cooling fan. If you get one of the results that indicates there may be an issue with your fan, it’s time to contact Apple. Support or visit your nearest Genius Bar for a repair.

Reset the SMC

If your Mac is clean and grime-free and you are keeping your apps and tabs in check and the fan is still spinning frequently and loudly, then try resetting the System Management Controller (SMC). The SMC is responsible for controlling low-level functions on your Mac including “thermal management,” aka the cooling fan.
