I have had the 720 15" for almost a year and just recently been experiencing a problem with the fans. The fans are running even when I shut the lid of the computer and the computer is in sleep mode. The only way for me to stop the fans from running while the computer is in sleep mode is to manually power off the laptop. I am not sure why the fans just start to run even during sleep mode since this was not an issue previously.
