I just read this review on amazon and through it was worth posting: " UPDATE: (May 6th, 2011)..I started to notice my Macbook Air getting hot so installed iStat then ran some informal tests. As I suspected, the Speck Products Soft Touch Hard Shell case causes the MBA temps to rise. 04/12/2011 8pm CPU 56*C and GPU 59*C running Safari and iTunes without Speck Hard Shell 04/12/2011 9pm CPU 83*C and GPU 91*C running Safari and iTunes with Speck Hard Shell. that's a whopping 47% increase! --shutdown Macbook Air and removed Speck Hard Shell, stayed off all night until next morning 04/13/2011 8am CPU 31*C and GPU 33*C without Speck Hard Shell 04/13/2011 10am CPU 55*C and GPU 61*C with Speck Hard Shell added. That's a a HUGE increase 75% Bottom Line: I have removed the Speck Hard Shell permanently as I observed significant rise in CPU as well as GPU temps. Conversation with an Apple "Genius" named Austin revealed the Apple Macbook Air's aluminum Unibody chassis is partly responsible for some heat dissipation and Speck Hard Shell inhibits the escaping heat. " I used a see thru satin on my 11" c2d and always thought the fans came on as the processor was struggling causing the temp to go up. I now have one on my i5 and the fans were blazing away on the same tasks (normally if i stream something from the net) so I did a quick google and it seems that the case does cause a heat increase. I find it annoying this happens as I like to look after my high value items and protect them from any possible damage hence using the case (and moshi palm guards) Has anyone else experienced this?
