Your question has many answers depending on several factors. Is the C4/LT5 modified in any way that would affect power output or normal operation? What type of driving are you doing? Is the exhaust system modified? Do you ever go faster than the speed limit? Do you use the C4/LT5 for off road driving or racing?

I believe that a stock C4/LT5 with a stock radiator and fans that has no debris in the air flow path will operate in the normal temperature range.

If you make any modifications that increase power, you will have to modify the cooling capability to keep up. Or, as a minimum you will have to ensure that the air flow through the radiator is not reduced by debris.
