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.

Excel 4 Upgrade -- Mark H. Anbinder writes, "Microsoft Excel customers who are stunned by the zippy release of Excel 4.0 and are interested in upgrading will be pleased to learn that they can upgrade for pseudo-free (there is a $7.50 shipping charge) if they purchased Excel 3.0 after 15-Feb-92. Customers should call 800/426-9400 and should have their registration information handy. (Please call after 25-Aug-92, as Microsoft's entire sales division has been partying hard at an annual sales meeting (we're talking Mr. Bill running around with a squirt gun, to judge from a second-hand eyewitness account) and will be swamped when they return to the normal routine on 24-Aug-92!)."
