Is Retail Duron HSF quiet?

[theplanb]

I was just wondering,
how noisy are those lil fans that comes with retail durons?
1 can't hear a thing
2 barely audiable
3 sounds like a breeze
4 starts to get on your nerves
5 very irritating

It'd fit around #2-3. Nice and quiet. It depends on how loud the PS and other compenents are.
