During cruise; we received a FWD Equip OVHT message. We ran the QRH for the issue. While that was being resolved; we received a Cabin Altitude Master Warning. We donned oxygen masks; attempted to control the cabin altitude. That didn't work; so we executed an [expedited] descent and [advised] ATC. They vectored us to the nearest suitable airport. Attempts to contact company in the air were unsuccessful due to high terrain. We landed without incident.Equipment cooling checklist should discuss going to OVRD in single pack operations and the possibility of a cabin altitude warning.
