princejoe, the SK6 should still be quite a bit better than a Volcano7, plus the reviews of the Volcano7 are very conflicting: some say it's good, some say it's bad. Given my experience with ThermalTake products I think it would be decent, but NOT an oc hsf.
I've owned a DragonOrb3+ myself, and while it performed well (although not as well as some reviewa said, and they placed behind the SK6, which means that it's surely worse, but still okay) it was VERY noisy, the fan on it is a 7000rpm Delta Screamer copy, and Anands september heatsink round-up said it was louder than that! A final thing about the DO3 is that it's got a very tight install, while it's nice it uses a 6 "hands" on the socket, it's hard to get on (if your hand slips it'll be quite easy to crush the core) and it's very heavy.
You cannot use a heatsink without a fan on the faster cpus, even though it's a good sink the cpu makes so much heat that need to get away fast and to do that you need a fan. There's quite a few people who have replaced the Delta Screamer on the SK6 with a slower fan and still get good results, you could try that.
