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.

Free Book for TidBITS Readers -- All right, so this is a bit odd. A couple of TidBITS readers, Audri and Jim Lanford, run a Web site called, where they publish information aimed at busy people in a variety of different formats, including PDF-based electronic books, or ebooks. To create a promotion aimed at introducing people to their ebooks, Audri asked a bunch of experts (a category Audri evidently thinks I'm in) to contribute a short piece of advice on how to improve one's business. Being an agreeable sort, I sent her the main piece of advice I offer based on how I've run TidBITS. Audri and Jim have now compiled all the experts' advice into a 104-page ebook - 43 Specific Ways to Make 2002 Your Best, Most Profitable Year Ever - and are offering it for free to TidBITS readers via the URL below. The promotional text is a bit breathless, which sets off my warning bells, but they avoid dubious stuff: Audri told me downloading the ebook sets only a session cookie, and you're told ahead of time that you'll receive a companion newsletter, from which you can unsubscribe easily. The real question is, apart from my insightful words of wisdom, is the content of the book is any good? After reading the entire ebook, I'm happy to say that most of the advice, though concise, makes important points that could be useful to anyone. Don't be fooled by the brevity of each piece - many require more thought than can happen while you read. (Full disclosure: if you were to buy other ebooks from after downloading this free one, TidBITS would receive some small affiliate fee.) [ACE]
