Narrative:

[En route on an overwater flight] the EICAS 'fwd equip ovht' (forward equipment overheat) message illuminated along with the overhead 'overheat' light. The captain ran the forward equipment overheat checklist. The light re-illuminated after 5 minutes and the system had to be run in 'override'. After reviewing the systems and discussing the situation with dispatch/maintenance a return was elected. An emergency was declared and we diverted direct to [nearest suitable airport]. Once with the next center the emergency was canceled; followed by a normal approach and landing.
