I don't have tons of personal experience (can only physically confirm the HPL-815). I just read A LOT of articles and other people's experiences.
I'd go with an H60 or H80 though. Sure it is overkill but it keeps things much cooler and is sort of easier to deal with. Although if you are just sticking with stock speeds, anything will work really. The NT07 is the closest to a normal stock cooler. It accomplishes the same cooling at a much quieter level and is smaller than the stock cooler. The HPL can be a little loud with the stock fan so it's good to change that out. It's an 80mm for reference.
Armour you da man
I took your advice. I flipped the PSU over, flipped the top fan to intake and the side fan to exhaust and voila my cpu temps dropped around 10-12C. Previously I let the Heaven 3.0 bench run maxxed out for an hour and my cpu would get up in the high 70's and my gpu would hover around 75C. After making the changes, my cpu stays around 60-62 and my Gpu stays around 72C and that is whisper quiet, with a pretty good overclock on my GPU. Overall I am extremely happy with the results, I see no real reason to spend $$ on a new cooler. I think my temps are pretty damn good considering the size of my case and everything I have stuffed in it.
Thanks again for the advice Armour
