Yeah, it took me a while to figure out that ring too. It might not be hugely important, but it helps when mounting it. When you slide and twist the mounting bracket onto the cooler, the ring is supposed to be snapped on from the bottom, locking the bracket onto the cooler. Not an easy maneuver in itself (the bracket keeps sliding off the groves and the ring won't reach), but it makes the rest of the mounting a lot easier. But since the other cooling solutions often seem to be using the same cooler, I assume they have the same problem. It might explain the temps if it didn't get properly mounted.
I'm not surprised that it's worse than the H100, that beast has twice the radiator surface for cooling. Though, it really should be better (or at least quieter) than the stock cooler...
It was definitely installed improperly. I was able to figure out the right procedure from instructions on how to install an H70 the right way - lots of people seem to be doing/teaching the wrong way. But even knowing how to do it I couldn't get all three pieces together before finally giving up in disgust. So I'm just going with the stock cooler for now. It's quiet enough and the temps under load are no worse than a badly installed 620. Idles in the low to mid 30s in a 72 degree room.
Thanks for your help.
