EVGA M020, Noctua NH-U9B or Corsair H100?

The layout of my new motherboard has forced me to rethink my cooling situation as the sheer size of the heat sink I'm using now blocks access to some of the critical ports on the board including the CPU fan and the 4-pin power connector. And my system temps are through the roof with it idle at 45'C (my SB build idles at 21'C) and on full use generates a lot of heat at 55'C (SB heats at 30'C).

I chose the EVGA and Noctua coolers because they're significantly smaller than the one I'm using now and way more efficient, and they both perform the same as a single 120mm radiator like the H80 would.

I really want to get a smaller air cooler, or possibly go H100 (my case is a Corsair and has the mounts for it), what would be my best course of action here? Cooler must be AM3 compatible.

Personally I think the Corsair is the best, I have used Corsair alot in the past and use it in most of my other rigs, as do my friends.

I don't think you will see much difference in temps between the 3 and as you have Corsair case, the cooler will mount better and probably look better.

What did you choose in the end?
