[Solved] I7 aftermarket cooler without backplate

I have a zerotherm zen cooler sitting around and I'm just about to get around to overvolting my cpu. When I overvolted using the stock cooler, the temp got up to 80c using prime 95, so I shut it down and started looking at aftermarket coolers. I have a zerotherm zen (which actually does perform pretty well) but what I'm worried about is the fact that the available bracket for LGA 1366 has no backplate. It's intel's spec pretty straightforwardly, and I'm wondering about the weight and if anyone has any similar experiece with x58 mobo's aftermarket coolers who have no backplate (that are about the same size and weight).

I already own the zerotherm zen, I've had it for a while now. It's not that I don't want to, but that the attachment mechanism for the zerotherm zen has no backplate for it's i7 bracket. I'm wondering if anyone has used a large cooler like this with no backplate and had it fail or succeed. That's what I'm asking.

EZ, have you gotten urs yet?
