I was originally planning on getting an h100i, but decided the very small possibility of a leak is not worth it to me, so now I am trying to decide between the nh-u14s and the d14. I've read some reviews and all of them say that the u14s cools better, but a lot of people in forums say the d14 is better so I am kind of confused.. So which one is better? If I was to get the u14s I would get an extra fan.
