Not fake news. Bad science. In a heat exchanger, the rate of heat transfer across the boundary is related in a fairly complicated way to the mass flow rates on both sides of the heat exchanger and the temperature difference. In simple terms, - no air flow and you overheat, no matter how fast the water goes through, and no water flow you overheat, no matter how fast the air flows. But there is no circumstance where higher flow on either side of the heat exchanger would reduce the heat transfer.
