If you have a big wallet then the Thermalright heatsinks are good, almost any of the SLK series.
I would recommend for an easy budget something like the Coolermaster X-Dream (HAC-V81) which has an adjustable fan and works pretty well.
My next suggestions is the heatsink I have, the Coolermaster HHC-001 which is also very good and includes a heatpipe which is awesome. My CPU stays pretty cool and it isn't too noisey, isn't quiet either. This heatsink I would highly recommend.
