Best NVIDIA GTX 980?

Solution
The reference cooler is great for removing the heat from your case. With the reduced wattage of the GTX 980, you get the benefits of an overspec'ed cooler running slower for even less noise.
heard good things about the acx2.0 cooler on the evga, other than that the reference blower designs would allow easier water cooling if that is your thing down the road... the asus reference design is also tempting.
