Still using it, and still going strong! Since the picture, i've removed the PSU mounting so i had a bit more space, and squeezed the noctua 25mm in there, in place of the 14mm, gave a nice little boost in cooling and noise.
I've actually rebuild the PC yesterday, i'll post some pictures soon, i'm now using an HDPlex 500w DC-ATX underneath the gpu after my SF450 died, should be quite interesting.
This means i have now put the Alphacool 92mm rad on it's side so it has better acccess to fresh air. Wasn't able to get any benchmarks yet (also not sure anymore at what temps it ran before, but i know i wasn't able to sustain a 5ghz OC before, so interested to see how close i can get now.
Long story short, the cooler is doing great, still low noise, pump is barely audible, and cooling great! What CPU are you thinking about using it with?
