Whats a good heatsink that cools well and would fit on a ga-7dxr without any problems?

I have a swifttech on there but Its a bit of a pain in the ass to get on. Plus I don't think its seated proplerly because my temps on mbm are 47 c idle with two 120mm, one 80mm panaflows, swiftech and delta combo. The case temps are 23 c so I know I got good ventilation. I reseated it several times and yes I am using artic silver on the core. each time I reseated it I cleaned the old silver off and applied a thin coat with a razor. So I did all the right stuff to no avail. So I'll just get another hsf. I want to overclock this chip. Thanks for any help.
