X1 DVR Box Fan Noise

I recently had my Xfinity service installed, and unfortunately the constant fan noise from the DVR is very loud and noticeable even in adjacent rooms - a constant high pitched whirring. The box is a PX013ANM. In reading through the forum it seems like this is an older box and that a newer/upgraded one solves this issue? Are there other alternatives to fix this?

Thanks in advance.
