Any price range or performance range you had in mind cause i can think of a lot of heatsinks and water coolers.
eg. what speed are you trying to hit?
as for quiet and efficent cooling that is easy to instal and reliable i would suggest looking at noctua all the heatsinks come with thermal paste in a tube and have lots of mounting brackets so you wont need to buy new things to move CPU'shttp://www.noctua.at/main.php?show=start
their site contains all the info you need and a varying price range with a list of compatible motherboards and RAM Etc.
there are also closed loop water coolers like the corsair h50 and h70. and for lower budget heatsinks i would suggest coolermaster.
for thermal paste if you ever need to buy any because your moving mobo's and or CPU's i would suggest Arctic silver 5.
