Known as the finest fan ever made for the compact Macintosh. Very quiet, much quieter than Kensington's copycat version and better looking since it fits flush to the top of your Mac.
Draws air through the top of the compact case to give your Mac a breather, and keep it an alleged 20 percent cooler. It kept my 4MB Macintosh Plus working in south Florida for years, with no part burnouts whatsoever. Also serves as a mini-surge protector, though that's a minor point.
The Fanny Mac plugs into your Macintosh power port and a separate cable goes to the power outlet. Standard cables as shown. All-in-one, quality unit. Lastly, this major solution product allows you to put your Mac in a cabinet or closed environment because the power on switch is now on top of your compact not behind it. Worth it's weight in platinum: Fanny Mac. Still working fine with typical quiet efficiency.
