How Loud Are Your Mac's Fans?

When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.

Send Article to a Friend

Apple has released MacBook Air and MacBook Pro Update 1.0 for the models introduced in June 2012: both 13- and 15-inch sizes of the MacBook Pro, the MacBook Pro with Retina Display, and both the 11- and 13-inch versions of the MacBook Air. The minimal release notes say that this release “fixes an issue that can lead to increased CPU power consumption, and it improves compatibility with some USB devices.” Requiring Mac OS X 10.7.4 Lion, the update should appear in Software Update for affected models, or you can download it directly from Apple’s Web site.
