It looks better, but still slightly curved. There's a pretty good write-up over at HardOCP

Don't mean to barge in, but I think it's funny that this site advertises a Lapping kit with that heatsink.. LOL I've heard a lot about that contact patch not being exactly TRUE... lol

I really like Thermalright Heatsinks and I'm sure the Venomous X will be a Solid Performer. However, after reading the link you supplied I found this.

They just won't learn, Lapping will still be required.

It's when you smooth the surface of a heatsink or processor using varying grits of sandpaper so they make better contact. Better contact means better heat transfer and lower temps . Here are a few vids so you can see what it entails (thanks to Slay for posting them):

Here's a 2-part video on lapping your cpu. It's easy to do, you just have to be delicate

Thanks a lot. By the way, does the NOCTUA NH-U12P SE2 needs lapping?

It shouldn't. You can check it for flatness with a good Straight-Edge (a new utility knife razor blade).

If it's flat, but lacks a mirrored finished, you can always just polish it up with some 1500-2000 grit sand paper. But it's not necessary
