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.

Two Corrections in TidBITS 827

Send Article to a Friend

Two Corrections in TidBITS 827 -- Alert readers pointed out two corrections in last week's issue. In Mark Anbinder's article "MacBook Pro Line Adds 17-inch Size," the specification for the new laptop's SuperDrive should be 8x speed, not 4x (which Mark correctly wrote in his ExtraBITS post on the day the computer was announced, but got mangled when editing the issue).

And in "Tools We Use: Backdrop," I incorrectly wrote that one could take a screenshot in Mac OS X using the keyboard combinations Command-3 or Command-4. Since I (along with the rest of the staff) use Snapz Pro X to capture screenshots, I rarely use the Mac OS X shortcuts, which are Command-Shift-3 and Command-Shift-4. Thanks for keeping us (me) on our (my) toes! [JLC]
