From the limited knowledge I have about the LS platform, the way I understand it, they perform better at a higher temperature.
I do know that, looking at the factory fan settings on my LS1 (stock thermostat I assume), they were set to come on at 226º which seems a little high (to me).
I adjusted mine for 195º and 205º (fan1, fan2)
I bought the Entropy LS swap radiator and when I was test running it, fan 1 came on at 195º so I know it's getting to that tempº (at least at an idle)
it will be a while before it gets on the road but I'm anxious to see how it behaves then.
