I'm putting a second computer together with a 3770k and intend to use a Noctua NH-D9L. I have all the parts at this point. I currently have the CPU at 4.4Ghz at 1.35v and it gets in the 70s (if I video edit, it gets in the 90s). It currently has an H80i v1 which is over 4 years old which is why I am moving over to a new cooler. Any ideas on what might work for OC'ing? What should I expect for OC'ing on air? Is 4.2Ghz on 1.3v a reasonable expectation? Any tips for OC'ing on air?
