Lowering the water temp 10F will help sometimes, but when the oil temp
decides to north of 260, lowering the water temp won't help much. In
addition, the heat from the oil is still being absorbed by the water
cooling system lowering it's available capacity. In extremely warm
weather, the the low temp t-stat and fan will accomplish little more
than running the fan more. Unless your stuck in slow moving traffic the
fan is a waste and does nothing more than help wear out the alternator.
If you really want to control the oil temps and add cooling capacity, an
external cooler with T-stat is the best choice.

If you have a cooler thermostat with a matched fan switch... then your
water
that does the cooling will be cooler...
