Probably careful monitoring of oil level and regular changes are critical to the long term health of the engine. An oil cooler would be nice but they are as rare as rocking horse s**t and many, many people get away with abusing their DRs without them. If you could locate one, it is a bolt-on addition to the outside of the engine (but also another potential failure point.)
Possible oil cooler options.
