Wherefore art thou, oh Socket 1207/771 CPU cooler?

It seems that the choice in CPU cooling solutions for these two sockets (Opteron/Xeon) is slim at best. I guess they aren’t volume sellers.
What I don’t get is why the powers that be sought to invent yet-another-new-cooling-solution-requirement that does a good job of fragmenting the market, and insuring limited supply of reasonable cooling systems.

Well, the Intel boxed processors at least come with cpu fans and coolers. As of socket 1207, Opterons no longer do.
And that is a royal pain.
Anyone out there have recommendations for reasonable CPU coolers for socket F? I have used all of them that I am aware of (and have mentioned). I would prefer lower noise units. Would like to avoid water cooling. Which would not fit anyway.
