single fan o dual fan?

[MiRai]

this is the card I´m reffering to:

EVGA GeForce GTX 1060 GAMING

is it more air flow better for multiboxing?

Well, if the card was made with a single fan, then they felt that it was capable of cooling the components on the PCB with only a single fan. EVGA didn't release the GPU with a single fan in hopes that people would never exceed 50% load or something like that. So, if you want to use that GPU, it's going to operate in the same way that any other reference GTX 1060 is going to.

That particular GPU has been out for over a year now, and EVGA was able to engineer the base 1060 into a small enough PCB where only a single fan was required, whereas two fans are required to cool a larger PCB.

I mean, it obviously consumes more power, I would like to know if it´s worth to go dual

I can't imagine that an additional fan uses more than, say... 10 watts, at most—something completely negligible, and nothing that anyone would ever budget their PSU around.

The two different fan setups are rated to run at the same base and boost clock speeds, so there should be no difference between them.
