Green, silent 140mm fan?

Hi,can someone recommend me a 140mm fan with green LEDs? It has to be silent and pull some air into my case (for the front). I guess it also needs a four pin connector for the motherboard to control it in the bios.

Thanks in advance. First post ftw! Great site. 

Welcome to the forum! Deleted your duplicate post for you; site messed up, not you.

How much are you willing to spend?

Ty. Up to 20$ is ok, more or less.

Cougar Dual-X Green

Bitfenix Spectre Pro

Those two are the quietest afaik.

+1. I have 2 betfix spectre pro fans, those things are so damn quiet and pull a lot of air for their price. 

Thanks alot! Just ordered the Bitfenix, looks awesome. Got it for 20$, too. :)
