I knew that, and probably could've chosen my words better. Higher wattage cards with better coolers can still run at equal (or lower) temperatures than lower wattage cards with weaker coolers, especially in some niche situations like tight cases or poor ventilation. This is what I was trying to allude to with the word "often" rather than "always." Perhaps I should've said that higher wattage cards will produce more heat, and the coolers may or may not do a good job at compensating adequately for every situation.
