Just a few guesses based on your description so far would be undersized (aftermarket) electric fans, too much antifreeze in your coolant mixture, or a bad water pump.

What coolant mix are you using? Couldn't hurt to change the thermostat I guess...it's only a few bucks. Water pump could still be bad - just because it cools okay while idling doesn't mean it's working well enough to cool while putting out 700rwhp.
