Humming Sound from Lenovo yoga?

I got a brand new Lenovo yoga, And there's a humming sound, and the fan is always on. Always. Is there any way to turn down the fan noise. Its quiet for a fan, but its always on. And to the humming noise, its different than the fan. Maybe the hard drive. Whatever it is its annoying. Other than that its a pretty good computer.

Do you turn off the PC properly and if you do, do you close lid before its done shutting down. That may be it. The fan should not be running if the machine is off.
