Hey guys I am having a customized home built system. I am using Windows Xp operating system, MSI P55-GD80 mother board with i5 760 4.0Ghz @ 1.26v.now I am thinking to purchase a new cooling system for my system. I am little bit confused between the two of them: Corsair Hydro Series H70 or Antec KUHLER H2O 920. I am really confused between those two. Can anyone kindly suggest me which one is better in closed water cooling system?
