Hi guys, I really need help with which fan to buy? What I have right now is just a stock fan of an AM3 phenom II X6 1090T processor. It goes with my ASUS crosshair formula IV mobo. The stock fan is getting really noisy and my core temp elevates up when playing games such as battlefield etc. I am in the verge of buying Corsair h50 or h70, or Zalman 9900, but I really need the majorities opinion first. Maybe you could start with the things I need to consider as well. Please enlighten me on some things I might want to consider getting. Thanks
