I think its just a FOP32-1 with a YS-Tech Fan (according to ad) and I don't think it will leave you with any room to overclock. Its not that high end of a heatsink.
Lot of people been having success with the Golden Gate (Gladiator)heatsink, never tried it myself. Not sure where to get it but if you do a search there has been tons of people using it and I think its only like $25 dollars if money is your problem.
