Which 140mm PWM FANS to choose for my new NZXT switch 810??

Hello guys,

I have a problem with chooseing fans for my new NZXT switch 810 as the stock ones make grinding noise and are loud and probably not that great in matter of performance. I m looking for something like Thermalright TY 140 - quiet and high CFM + nice price (thermalright wont fit in the case since its 160x140 not 140x140 fan unfortunately) . Im gonna use it with my new rig which is already built - Rampage IV Extreme , i7 3930K - gonna use Corssair H100 with dual Cougar Vortex 120mm PWM fans and the last thing which keeps me from doing perfect cable management and close the case is the fans. I checked alot of sites and my mind os overrun for all those suggestions and things . So , what fans (the best would be PWM - in fact im interested mostly in PWM fans - i dont want to use fan controller) would You guys recommend ?
