Though I have no idea if they can be bought anymore, I can recommend
Mist Frostbite 120mm fans.
Else I'll most likely use these:

Yup, danish, so a few explanations; CFM/dBa.. should be understandable.
They feature SSO-bearings (Self Stabilizing Oil pressure bearings).
The dBa ratings are with/without the noise adaptor thingy.
I'm about shopping them for my G4 dual 800, plus doing something about
the noisy cpu fan/duct, which I believe is a mix of the actual fan plus
the hissing noise produced by the smallish duct ending in a grill on the
rear of the box. Had it been a PC I'd simply cut that grill off..
Dunno yet which fan I'll use for the PSU.
