Does it matter if a GPU has 1 fan or multiple ones on OC'ing?

So I'm getting a 7950, but I need it to be on Amazon (Since I live in PR and shipping is $20 more on any other website) and I want the 3 free games, but I'm planning on OC'ing. Does it matter if the card has 1 fan or multiples when I'm going to OC?


NOTE: This is a gaming only PC.
