Yes, it is a very tight fit. However, with a little massaging and the heat gun, I was able to get it to fit snugly. Those included blue USB cables are quite stiff and need a little heat for encouragement.
I would recommend bending the USB cables with heat, plugging them into the adapter, and then mounting the fan.
Funny, I bought one of these noctuas thinking it was the right size, and when I received it ended up not putting it in. After seeing this post, I ran and crammed mine in the case. A couple of things... (begin stream of consciousness)
First, I am really tempted to drill some new holes, either for the fan (to shift it over a bit to not block the front-most ssd slot) or for the ssd's (so that they can be positioned differently to not interfere with the fan, although I haven't laid it out or done the math).
It would be pretty sweet to see a version of this case with support for these fans. I think if you nudged things around a bit, you could get away with just adding 10mm to the top (above the motherboard) and then sliding the ssd's up a few mm, and you'd be able to use the 60x25's on both sides. Adding .2 liters isn't ideal... but it would be worth it for better cooling.
I'm sure there are serious flaws in this (especially wrt different configurations) but if it's viable I think it would eliminate my only gripe about this case.
Also, the position of this fan is slightly odd to me. It seems like it should be closer to the riser card. Couldn't you fit two of them if you had an angle connector and the first one was up against the riser? And does it make sense to have this fan pulling air into the gpu or should it be pushing? I assumed pull since it's on the bottom.
