I'm happy with the 3x SW3 HF I bought at least, They are basically completely silent at half speed(50% ~1100rpm) and can have a little noise above but it isn't much compared to the old fans I had that are much louder at slower speeds.
Though I noticed they only spin ~2000rpm on the motherboards I've had (a gigabyte and a Biostar)
