Best Silent 140mm for Radiators

I need some suggestions for the best 140mm fans for a few radiators.  I threw in a few NZXT fans and they are super loud.  I just need something quite and good static pressure capabilities. 

 Noiseblocker NB-BlackSilentPRO's, they were the quietest 140mm fans Ive used on rads especially at 5v or 7v. Decent enough static pressue to boot.
