MacBook Air 13" Mid 2012 AirPort/Bluetooth Card
Lewis: simply running the Macs Fan Control app will do it. Otherwise the fans run at full speed because they have no temperature measurement.
As a note, my Mid-2010 Unibody Macbook did not have this third screw, just two to remove the battery.
Thanks for that warning, Andrew.
