It does fit if you want that case. If you tight these 4 screws around it shouldn't have any problem.

Water Coolers are not that easy sometimes when it comes to case compatibility. Usually, to be safe, make sure the case manufacturer says 240mm radiator mounting. Also, sometimes the holes may be there but there is no space between the mobo and the top of the case to fit properly one. That's the case with my...case for example.
