cpu and noctua d14 will work fine together. Iono if you can fit it in the case though, dont have one. Just make sure you have clearance on your motherboard with the memory you are using.
 
One of the best heatsinks out there, though not the best value. If all you want is a moderate overclock like 3.6 to 3.8 ghz which that cpu will be able to do with stock voltage, I would just get this.

Buy a second fan for 5 bucks and with stock voltage and a clock around 3.8 the difference between those heatsinks will only be a degree.

I have put that heatsink in the Antec 900 several times and the noctua is 2 mm taller so they will both fit.
 
Hyper 212 Plus is supposedly a good heatsink - I've not used it but I think it's considered the best for the money for mild overclocks. I can tell you my hyper n520+ couldn't handle a 4.0ghz overclock at 1.35 voltage to save it's life. It would go to the 100*C throttle temp in about 15 seconds after starting prime95 with eight threads. I tried mounting it twice to ensure it wasn't just a bumbled mount job. Then I read on other sources that the heatsink just was not up to the task and that others have had the same heat experiences. The hyper n520 is more expensive than the hyper 212 plus and both are made by coolermaster, but I never found a review comparing the two heatsinks directly. I ended up with the n520 because they were the same price at microcenter and I figured the more expensive at retail price one was surely better. That may not have been the case. I ended up buying a corsair h70 which works great to cool my 4.0ghz overclock never really breaking low 70's in any normal task and staying within high 70's on prime95 for the most part. That's with a single fan as compared to the stock configuration of dual fans which I find too loud.

So I would not recommend the hyper N520 for a bold I7 920 overclock. I'm not sure how the Hyper 221 Plus compares - but I do know the Hyper gets lots of positive reviews.
 
Here is a chart that has them both on a test bed designed for repeatable results with a specific heat output. Also this test is with only one fan on the 212+ and two on the Noctua. Temps will improve a couple of degrees with another fan attached.

Also I7's tend to run pretty cool (for an i7) up to about 3.8 ghz or so. After that you start needing more voltage and you get much higher temps to get into the 4ghz range. So if all you are looking for is 3.8 get the 212+ which is probably the best HSF out there for the price right now. If you are looking to go to 4ghz+ get the Noctua to try to eek out your best overclock.

Also take into consideration what motherboard you have and the north bridge heatsink and the ram. That Noctua heat sink is absolutely huge. It will fit in that case, but it might not fit on your motherboard.
