Siper the little concertine metal wafer in the rad corrodes. It might LOOK fine but if you give it a prod you may find that in areas it just falls away or crumbles.
Also check your thermostat. If faulty it should default to open but of course it could fail when jammed shut!
Water pump impellor could still be faulty. It could slip as easily at idle and be fine at speed as the other way round.
