I'm sittin here bored so I figured, why not try and make my pc cooler?
It will be the rear fan on my NZXT Phantom 630. Here are the options...

Which one should I use? Also, there is a place on the bottom of the case for 2 fans should I add any, as I have a lot of fans and even more time on my hands.
Thanks guys, all opinions/facts are accepted.

I have been impressed with my two Cougar 140mm fans. Saves a few bucks too.

TME, there are a lot of good fans out there. That said if you want to save some money pick up some medium or high speed Yate Loons, you really can't beat them for the price. I recently bought some BitFenix Spectre Led Pwm fans and they are really nice. They sound great at 100% and are almost equal to the Gentle Typhoons I have with sound quality.
