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.

Adobe has released Lightroom 4.3 with support for 20 cameras and 42 lens profiles (including the iPhone 5) and fixes for a variety of bugs. Amongst the highlights, the professional photo cataloging and editing application fixes a problem with uploading to Flickr if the photo’s filename contained an apostrophe, ensures that Catalogs from Photoshop Elements 11 are updated, properly imports AVCHD video, fixes an issue where TIFF images could experience a tonal shift, and fixes a flickering problem with videos created on the iPhone 4. Additionally, Lightroom 4.3 now supports Retina displays when using either the Library or Develop modules. ($149 new, free update, 419 MB, release notes)
