Hey guys, long time lurker here. So I finally bought a DP > HDMI adapter, so i can use my Macbook Air 2012 (i5, 128Gb SSD) at home with keyboard, mouse and external monitor as my main computer. But I can't get over one thing - it gets really hot when I'm streaming video online (Youtube for example), fan starts spinning like crazy, especially if this is HD video and upper left corner is really hot. Now i've tried a lot of things, tried different browsers, even clean installed OS X to make sure this is not a software issue, lifted it up from my desk with a makeshift stand, but result is still the same - fan is really loud. Is my Mac working as intended? Does your Mac get really hot when streaming flash video, while using external display? I'd really love to use my notebook as my main device, but i'm really disappointed with its' performance right now.
