Greetings folks I've read through quite a bit of posts around the interwebs, as well as looked through a couple of reviews for these products. I've picked up an Asus M5A97 for cheap to replace my current mATX, up-to-95W-only M5A78L-M LX motherboard. If I understand correctly from what I've read, the M5A97 is not really a known "beast" for OC'ing, but I'm thinking I will fare a great deal better in the overclocking department than I ever would/could have with the M5A78L-M LX. The point being, I'm looking to drop either a Phenom II X4 955 BE or 965 BE in there and try my hand at getting the best OC possible out of this board. I really like the looks of the Antec Kuhler H2O 620; and from what I've read in reviews, it performs about on par with the Corsair H70. So for the Corsair Hydro series, I would likely go to the H70 if I end up with that company's product. However, it seems that I could get the Antec 620 for cheaper than some places sell the H50's and even H40's for, so it really doesn't seem worth it to go with the Corsair unless I go with an H70 or higher, which is more expensive than the Antec 620. For what I'd pay for an H70, I could buy the Antec 620 plus an extra good quality second fan for push/pull on the radiator (which is what I ultimately want to do). I currently have a Hyper TX3 with a push/pull fan configuration (which really doesn't do much on this cooler), but I wouldn't mind going with a Hyper 212 Plus or Evo in push/pull if I ultimately decide to stick with air cooling. I could save a bit of money if I went with the 212+/Evo w/ a second fan over the Antec 620 or any Corsair Hydro cooler.... but I really like the sound of having a liquid cooler. The thing is, I don't know if the Hyper 212 series in push/pull would perform about the same, worse, or better than either of the liquid coolers with the same fan configuration. My question is: For what I'm looking to do, which would be the recommended buy? Like I said, I've read various posts and reviews already, but nothing really seems conclusive to me and I'd like to hear from people who have experience with these products to see what they have to say about them.
