AMD Phenom II x4 955 or 965 cpu fan help

[wasabi91]

Hi guys, i just bought a new motherboard
ASUS AMD Socket AM3 790X/SB750 New Generation 8+2 Phase Power Design ATX DDR3 1066 Motherboard M4A79XTD EVO
and i plan on buying the AMD Phenom II x4 955 or 965 and i was wondering if anyone could help me find a cpu fan that will keep my cpu cool, has a 4 pin plugin, isnt over 6.5 inches in height, and i would like one that i can install without removing the backplate off my motherboard.

Feel free to post any suggestions
Thanks

That last request is the killer. Most decent heatsinks need their own backplate to apply sufficient pressure. I think you may just end up taking that backplate off (unless your case, like mine, has a nasty cable system in the backplate: I just unscrewed my mobo, got the sink on and screwed it back in).
I got a Xigmatek SD963 because of height; it's 5.3 inches.
