New Corsair Fans run pretty loud

Hey guys, just got some Corsair Quiet Edtion AF120's they seem to be extremely loud in comparison to my NZXT fans which i've had for about 3 weeks now, which got me thinking, do fans take a while to kind of break in (or what ever the term is). I could lower the RPM however I don't have anything to do that with until my fan controller comes.

Thanks 

Yeah, mine are pretty loud too. I have 4 sp120's in push/pull and 2 af120's as exhausts at the top. It seriously sounds like a jet engine when i turn it on. Thankfully it dies down a bit after posting.

Running full speed , the sp 120's are jets .

I *had* mine running at 5V .

If your mobo can , lower the RPM or use the included fan speed lowering extension ( should be a pair of 12 to 7 or 5 v adapters ) .

Do you know if they sell those extensions separately? I only have two of those for my af120's and NONE for my sp120's 

Ill get some fan speed lowering extensions, thanks!

Any low noise adapters, or even make your own .

Just avoid running two fans off one adapter , as the adapter can get quite hot .
