As you can see in the picture the radiator on the Enermax Liqtech 240 is not small, at 273mm x 27mm x 120mm you should ensure that it is compatible with your case or be willing to dig out the dremel to mod said enclosure.  The large fans run almost silently at lower temperatures and even when going full out this AIO cooler really does not produce a lot of noise.  As to its performance, [H]ard|OCP found it to be significantly better than the smaller 120 version though the price is higher than some of the competition however for some the quiet performance will be worth the price.  Check the full review here.
