Jet engine or X1 DVR box?



I have noticed a constant whirring sound from my X1 DVR box for some time. I have had occassion to relocate the box to a wood surface and the whirring is now amplified to jet engine level of decibels. I have read on here that it is the internal cooling fan. How do I get this replaced and ensure the replacement is the latest version? Corrollary question - any way to resynch the new box to the cloud copies of the recordings so they then reside on the new box?

Thanks in advance.
