Hi im planning to replace 5 fans on a htpc, 3 case fans 1 psu fan and one cpu fan,

in the above pic you see the psu fan is the same size as the case ones, with 2 differences, the depth and the connector is 2 pin instead of molex format.
questions: 1.)does someone know where to get a low profile (80mm?) with a 2pin connector?
2.) which silent case fans would people recommend?
3.) which cpu fans or, hs+fan replacement (for AM2), ive seen a scythe mini ninja shuriken, which fits the 65mm gap, but is that worth it?
im looking for "silent" fans ofc, case is a antec nsk1480 btw, thanks for your help.
