Might be obvious to us, but not to people like the topic starter — fans are just a part of the equation. I've got 2-fan Palit GTX 1080 cards (Super Jetstream and Gamerock) and 3-fan Gigabyte Windforce GTX 1080 cards — Palit are super quiet and cool, while Gigabytes are loud and hot. Gigabyte's coolers are so bad I'm not buying any of their higher-end Windforce cards ever again. So a triple-fan card might be a lot worse than a dual-fan card, the radiators are what matter the most.
