Most of the time yes.

You're talking about fans on a gpu right?

GPU wise the dual fan versions usually have larger heatsinks meaning more surface area and thus better cooling, the two fans can usually run slower than the single fan to maintain the same temperature which means less noise as well.  I have the single fan 1060 card and it runs really well so I imagine the dual fan versions would be quieter and or cooler still.

Two fans should be quieter than a blower style fan (single fan) for sure.
