I have recently been overclocking tremendously and really enjoy it, and I need to have my graphics cards and my processor on the lowest temp possible. I currently have my i5 2500k OC'd to 4.5 Ghz and its cooled by a Corsair H80i. Should I keep my H80i and just cool my gtx 660 ti's together without the i5, or cool them altogether. Also please suggest some water cooling kits to me that would work with my setup. Thank you.
