I bought the 410 after realising the X41 would not fit in my Fractal R3. NZXT state, "The Kraken x40 and x41s will fit into the case without any problems at all." I tried and failed. No matter what fans you remove, which way you try to fit the X41, it will not fit. I posted a comment on the NZXT site about this and it is still "awaiting approval", and that was 9 days ago. Way to go NZXT! I now have a Fractal R4 with the X41 fitted on the rear. My brief interlude with the 410 was both frustrating and disappointing, and my experience with NZXT customer services is best described as mediocre. As a cooler, the X41 is awesome.
In the below picture, the rad is pushed to the rear as far as it will go and the rad is pushed to the left so you see where the corresponding hole on the case is and the distance from each. Unless you are happy with making new holes in your case then it will not fit in the pre drilled ones.
