I think that comment was in contrast to what they said about the fan: > This option does apply a decent amount of cooling at idle and under load, it also moves the heat away from the board unlike the heatsink. I think the comment makes sense with that context, compared to a fan, the heat from a heatsink will stay near the board and make future cooling less efficient.

But with or without a fan, the point of a heatsink is to increase surface area for convection. A fan also aids convection, but instead by maintaining a larger temperature difference between the surface (however large) and the surrounding air. Either alone is good; both together are better.
