I've got a 2011 i5 Macbook Air, 256GB Hard Drive 4GB of ram. This things heat and the fan spins even running light apps. I'm thinking I may need a 2010/2011 or current Macbook Pro based on my usage. For the record, it's hooked up to 27" Cinema Display. All i have running is Dropbox, chrome, spotify, transmission, and excel. Is this normal? Using my previous Macbook Pro I almost never heard the fans unless doing something extremely CPU intensive. Here's a screenshot of iStatPro.
