Reference vs Aftermarket for SLI

[EpIcPoNaGe]

If I were to get a second 780ti to SLI with my 780ti Direct CUII, should I get the reference cooler or the ACX cooler? I normally would go with the ACX cooler but the problem is that I have a mATX case meaning the cards will literally be 5 mm away from each other if not less. 

 

If someone wants to buy my current 780TI, that'd solve my situation too

I'd say reference is better as there is the blower style fan, but get ACX if OC'ing. The reason blower style is better, is that it doesn't push air down the card, it goes through the  card out to the back of your case.

Yea try reference or an after market cooler that comes with a blower fan

Hm... What configuration should I put it in then? Bottom -> Top: Blower -> Aftermarket or Aftermarket -> Blower
