What Can I Do about a Noisy Fan?
On _my_ mind, is "Whirr!" That is, as long-as my iMac is On, the fan makes a whirring sound. How bogus.
My iMac was built in mid-2011, in China. [I felt Amazed at the low price, unlike my previous Macintoshes, which were Made in America. Caution, please: the skeptic in-me thinks, "Could this be the reason to Buy a New iMac from those _same_ Chinese?" I don't like Built-in Obsolescence! :-( ]
What do you think? This board is a Good Place to express my feelings! :-) I thank you.
iMac, OS X Yosemite (10.10.3), 4 GB of RAM
