Noctua nh-d14 questions

[amuffin]

How well does this perform in the case of overclocking a 2600k (4-4.4ghz)? Also will this fit in my case (cooler master haf 912)?

4.4ghz is no sweat at all with a D14. I have one on my 2500k at 4.8ghz and I could go higher.

It will fit.

4.4GHz is no sweat with the stock cooler.
Anything above that requires an aftermarket cooler.
But lozz08 answered your question.
