The FR2 is on par with the SLK800 (original) when both use the same fans. It's a very good heatsink especially if you use a more powerful fan. With the stock fan the FR2 is only adequate for stock speed CPUs and maybe some very moderate overclocking but it is extremely quiet. With a powerful fan it becomes real performer.
I suggest you just install the FR2 trying an assortment of 80mm fans. I think the stock one is 28cfm. Test it then try your other fan. Judge from there.
Maybe you'll want something more powerful, maybe less powerful.
I hear the Smartfan II is a good choice. It's adjustable and has good speed ranges.
