That HS/F looks very similar to the SVC GC68/69 with a big clip for those that aren't too handy with a screwdriver.

That's what I use on everything from a Duron 750 that I have to a XP2000+. I just picked up a few when they were on sale for $1.99 each with fan. The stock fan is a little noisy, but not bad. For the slower chips, I replaced the fan with a NMB fan that's about 15db and 19 cfm. Those systems are pretty much silent. For you, I'd grab something like this Speeze hs or the GC68/69 and then run a quieter fan like the Panaflo L1a. I'd suggest the NMB, but it might be a little light for a 1.6 and besides, I think it's discontinued at this point unfortunately because they make fantastic case fans.
If you wanted to spend a few bucks more, any large hs with a slow speed fan would do the trick. Too bad SVC isn't running the deals on the Thermalright SLK900A. When they were $20, I should've picked up a few more. You could almost run that hs on your chip without a fan.
