I have just retrieved the acx3 along with a nh-d14 thursday evening. My first coolers ever!!! Let the virgin alerts bellow aloud. Some tl;dr - Installed the nh-d4 on my 1100t yesterday, 'twas more rook-friendly than I could ever have hoped, this despite it being my first time removing/installing any stock/aftermarket cooler. Hardware still lives! My new temp highs are now lower than my previous-stock lows, and what an amazing feeling it is! =) Also loving the silence!
Now my hd 6970 is up! My second virgin voyage in 48 hours! If everything doesn't explode I'll be happy a happy lad. =)
