Cooler is OK but the real reason coolers are needed is that oil oxidizes at a high rate as peak temperatures approach 250 F. For every 15-20 degrees additional- oil life is cut in half. A more practical solution to the problem (and cheaper) would be to use a pure synthetic oil. You could run forever at 300F and higher.
