MacBook Air Software Update 1.0 [updated]

Available via the software update or from the following address:
http://www.apple.com/support/downloads/macbookairupdate.htmlr
This update is recommended for all MacBook Air computers, and addresses issues with video playback and processor core idling.
Third-party software that modifies processor operating characteristics such as frequency and voltage is not supported and should be removed before installing this update.
[Update] This update regulates two recurring problems encountered by certain owners of this machine, the unexpected shutdown and high speed running of the fans. The fact that this update is incompatible with software such as CoolBook leads us to think that Apple, in agreement with Intel, modifies the voltage of the CPU according to the demand. Lowering the voltage by some hundredths of a Volt has a very important impact on the temperature of the CPU.
