Is there a general consensus regarding two v/s three cooler fan (air cooled) setups? From what I've seen, it sounds like :

2-fan setups have larger physical fans than 3-fan setups, so they can push more air at lower RPMs and are therefore quieter.

Card thickness has a lot to do with cooling, as thicker means more heatsink / fin area.

So, my questions are, is the noise difference that bad, or are we talking minor differences that are drowned out by other factors? especially such as hashrate.

Also, am I right about the above?
