cooling system compatible with Alienware Aurora r4

first I apologize for my poor english.

secondly I hope this will be a reference for all those who wants to replace the cooling system in Aurora R4.

far away from all the problems we had with the original cooling system and the awful work that dell put it in this particular product. ( They didn't even send us an heads-up email about any potential problems with the cpu cooling system ! )

I actually lost faith in dell, so I decided to replace this awful cooling system before it's damage my $1000 cpu, and never use theirs cpu cooling ever again. 

so I want to ask you guys, those who replaced the cooling system with some other brands out there, what is the best choice?

because I am really confused, whether I take the
Corsair h80i, h80, h55 or
Cool Master 120v, 120m

and are they really compatible with the aurora ?
