ASUS GeForce GTX 580 DirectCU II
 

The ASUS DirectCU II cooling solution implemented features five copper
heat pipes and dual aluminium radiators. Two 100mm cooling fans push a
massive amount of air with minimal noise. While it's great to see such a
beefy cooling solution paired with an over-engineered video card, it
does come at the cost of three slots. ASUS claim it takes up two and a
half slots, but in reality you need three slots spare.
