Hello everyone. Firstly I'd just like to thank everyone who commented in my refurbished macbook air thread, the responses were valuable and I am only waiting to see if the price drops on refurbs if there is a refresh. This question is from a friend of mine with an ultimate 13 inch, and he was wondering if its possible to underclock the 2.13 ghz processor down to 2 flat. He said its getting hot while using video editing programs. Is this possible?
