Going by the fact that you said the Milo only has around 80mm space, the later one you linked to would be too tall surely? It has a 92mm fan, and the specs say it's over 130mm tall!You also need to make sure the the cooler doesn't overhang the top of the board by more that a few millimetres - the zalman flower will.
Also the milo also has only ~80mm clearance (after standoffs and mobo are subtracted)
Might need someting like this or this both have good user reviews, but the Zalman is much better if you have the budget
and the specs say it's over 130mm tall!
Sorry
