I got a noise a bit like a pulse jet after a while. I had already had some hesitations.
I am rebuilding the system back to Mavericks (which I like less than Snow Leopard but that backup is too old) from yesterday's Time Machine backup.
7 hours to go...
No more software update/downgrades for me.
I did the same thing. I erased my Mac mini hard drive and Yosemite, reinstalled Mavericks and Air 2.1.2. Everything is fine now. No noise, no crackling. I tried Mavericks with Air 2.1.3. and the noise and crackling came back.
